The difference between Earthing and Grounding

 The difference between Earthing and Grounding:

🔹 Earthing (Preventive Landing)

• Purpose: Protect Man

• Non-current metal parts are delivered to the ground

• A current does not pass in the normal situation

• A current only passes when there is an outage

• Prevents electric shock and reduces touch and step effort

🔹 Grounding

• Goal: protect system and equipment

• A current bearing connector (neutral) is delivered to the ground

• A current may pass while on normal

• Controls effort and behavior of breakdowns

• Reduces electric arch and transient efforts

A quick recap:

Earthing is Protecting the People

Grounding protects systems and equipment

First up: How to implement Earthing (Protective Earthing – PE)

Goal: Protect people

🔧 Simplified implementation steps:

1️⃣ Identify the parts required to be grounded

• Body / Enclosure

• Metal structures

• Electrical Panels

• stairs, barriers, cable trays

2️⃣ Metal parts delivery

• Using a Grounding Conductor (PE Conductor)

• Standard color : Green / Yellow

Touchdown point delivery 3️⃣

• Landing Rod (Earth Rod)

• Earth Grid at stations

• Earth Pit

4️⃣ Achieving proper ground resistance

• Usually :

• • 5 umm (general building)

• ( 1 ohm (stations and adapters)

• وم 0.5 ohm (Substations – Oil & Gas)

5️⃣ grounding tests

 • Earth Resistance Test (Fall of Potential)

 • Continuity Test

📌 IMPORTANT:

A current is not allowed to pass through the Earthing cable during normal operation.

Secondly: Method of implementing Grounding (System / Neutral Grounding)

Goal: system stability and equipment protection

🔧 Simplified implementation steps:

1️⃣ Spot the Order

 • Neutral Transformer

• Star Point in the alternator or adapter

Grounding method choices 2️⃣

Depending on effort and nature of the facility:

 • Solid

 • Resistance

 • Reactance

 • Ungrounded

3️⃣ Neutrals delivered to the ground

• Direct (Solid)

• or via:

 • Neutral Grounding Resistor (NGR)

 • Neutral Grounding Reactor

4️⃣ Tie in to the grounding system

 • نفس Earth Grid / Earth Pit

• With a clear functional division between:

 • PE

 • Neutral

5️⃣ system test

 • Ground Fault Current

 • Relay Sensitivity

• Touch Voltage (In The Stations)

📌 IMPORTANT:

At Grounding a current may pass while normal is on.

⚠️ Critical HSE point (a common mistake)

❌ Connecting Neutral with Body stomach

✔️ Neutral → Grounding

✔️ Body → Earthing

(Separation between them is mandatory after the point of source)

Reference codes and criteria

🔹 Earthing:

 • IEC 60364

• BS 7430

• IEEE 80 (Substations)

 • OSHA 1910.304 / 305

🔹 Grounding:

 • IEC 60364-5-54

 • IEEE 142 (Green Book)

 • IEEE 32 / IEEE 80

 • NFPA 70 (NEC)

🔹 Oil & Gas:

 • ADNOC HSE-OS-ST-06

 • ADNOC HSE-OS-ST-17

• API RP 14F / 14E

Executive summary (excellent for scrutiny)

Earthing: Attaching Exposed Metal Particles To Prevent Collision

Grounding: Connecting the system's point to the ground to control effort and malfunction behavior

SAFETY-STONES LAID IN A SWITCHYARD

 

In electrical substations for a variety of safety and maintenance reasons. They act as a non-conductive layer, reducing the risk of electric shock by minimizing step and touch potentials during fault conditions. Additionally, they help prevent the growth of vegetation, absorb spilled oil, and improve drainage, contributing to a safer and more easily maintained environment.

Safety:

Step and Touch Potential Reduction:

During ground faults, electricity can flow through the ground, creating voltage differences between points where a person might be standing or touching equipment. Stones, with their higher resistivity compared to soil, help limit the current flow through a person's body, reducing the severity of potential shocks.

Insulation:

The layer of stones acts as an additional layer of insulation between the ground and equipment, further minimizing the risk of electrical hazards.

Fire Prevention:

In case of oil leaks from transformers, the stones can help absorb the spilled oil, preventing it from spreading and creating a fire hazard.

Maintenance:

Vegetation Control:

Stones inhibit the growth of grass, weeds, and other plants, reducing the need for regular vegetation management and preventing potential interference with equipment or personnel.

Drainage:

The porous nature of gravel allows for good drainage, preventing the accumulation of water and reducing the risk of corrosion or other issues associated with moisture.

Accessibility:

The presence of stones provides a relatively clean and stable surface for workers to walk on, improving accessibility for maintenance and inspections.

Heat Dissipation:

Stones can also help with heat dissipation from transformers, further contributing to a stable operating environment, according to a voltage lab article.

By following this SOP, you can effectively maintain and clean your solar modules, thus improving their performance and extending their lifespan.

 Cleaning of Solar PV Modules is a very important O&M practice to keep the module efficiency up and ensure high output from the plant, here is the SOP for PV Module cleaning:

By following this SOP, you can effectively maintain and clean your solar modules, thus improving their performance and extending their lifespan.

Safety Precautions: Before starting any cleaning activity, ensure to take necessary safety precautions to avoid any hazards. Wear protective equipment, such as gloves and safety glasses.

Identify the cleaning schedule: The cleaning schedule can vary based on the site location, weather conditions, and the level of soiling. Develop a cleaning schedule based on the site-specific needs and environmental factors. 

Water quality: The quality of water is crucial when cleaning solar modules. High mineral content water may cause mineral deposits on the glass surface, reducing the module's performance. Water must be free from grit and physical contaminants that could damage the panel surface. Use deionized, or reverse osmosis and natural pH water to prevent mineral deposits. If RO is not available, rainwater or tap water with low mineral content and a total hardness that is less than 75mg/L may be used. As per various research the TDS should not be greater than 30mg/L. 

Cleaning solution/agents: Dilute a non-abrasive cleaning solution in water according to the manufacturer's instructions. The cleaning solution should be specifically designed for solar modules and should not contain any harsh chemicals.

Equipment Preparation: Before cleaning the modules, ensure that all the cleaning equipment, including brushes, sponges, and squeegees, are clean and free of dirt, debris, and other contaminants. Don't use metal objects or harsh abrasive products for removing caked on materials – scratching the glass on a solar panel can affect its performance as scratches will cast shadows.

Cleaning Time: The recommended time for cleaning modules is during low light conditions when generation is lowest. However, when sun shines during the day, the temperature of the PV panel rises and cleaning solar panels with cold water in evening may result in thermal shock/crack for panel which can permanently damage them. Hence, the best time to clean Solar Panels is early morning, when the plant is not in operation, risk of electrical shock hazard is minimum and also temperature of solar panels is not high. i.e. the temperature difference of cleaning water and the panel is less.

Water Pressure: Water pressure should not exceed 35 bar at the nozzle. Use of high pressure hoses for cleaning may exert excess pressure and damage the modules.

Module Cleaning: Start cleaning from the top row and work downwards. Use a soft-bristled brush or sponge to remove loose dirt, debris, or bird droppings. Wet the surface of the modules with water and then apply the cleaning solution using a soft-bristled brush or sponge. Allow the solution to soak for a few minutes, then scrub the surface lightly. Finally, rinse the modules with water.

Drying the modules: After rinsing the modules, use a squeegee or a lint-free cloth to remove excess water from the surface. Let the modules air dry completely before reconnecting them.

 🔍 Qualitative vs Quantitative Risk Assessment – Know the Difference.

Risk assessment is the backbone of an effective HSE system. Understanding when and how to apply qualitative and quantitative methods helps in making safer and smarter decisions.

🟢 Qualitative Risk Assessment

▪ Based on experience, judgment, and descriptive scales.

▪ Uses tools like Risk Matrix, JSA, HIRA, Toolbox Talks.

▪ Likelihood and severity ranked as Low / Medium / High.

✅ Simple, quick, and ideal for routine activities.

⚠️ Subjective and less precise.

🔵 Quantitative Risk Assessment.

▪ Based on numerical data, statistics, and probabilities.

▪ Uses FTA, ETA, Bow-Tie Analysis, Monte Carlo simulations.

▪ Risk expressed in numbers or percentages.

✅ More accurate and objective.

⚠️ Requires reliable data and technical expertise.

📌 Key takeaway:

• Qualitative methods help us identify and prioritize risks. 

• Quantitative methods help us measure and justify risk-related decisions.

—especially in high-risk industries like oil & gas, construction, and manufacturing.

The best HSE practice is not choosing one over the other, but knowing when to use both

Operation of a new utility-scale solar plant, such as the Trinity project, involves significant hazards related to high-voltage electricity, environmental conditions, and mechanical systems. The primary risks during the operational phase include electrical shocks, fire hazards, and environmental factors like extreme weather. 

Here is a list of operational hazards for a new solar plant:

1. Electrical Hazards 

High-Voltage Shock/Electrocution: Exposure to energized conductors, particularly in combiner boxes and inverters (up to 1,500 V DC), poses a lethal risk.

Arc Flash/Arc Faults: High-power discharges between conductors can cause fires or explosions, especially when checking energized equipment.

Persistent Energy Production: PV arrays generate electricity whenever exposed to light, making it difficult to fully isolate the system for maintenance.

Faulty Grounding: Improperly grounded components can lead to electrifying the support structures. 

2. Fire and Explosion Hazards

Electrical Fires: Caused by arcing, short circuits, or loose connections in inverters, combiner boxes, and cabling.

Battery Energy Storage Systems (BESS): If included, these pose fire and thermal runaway risks.

Toxic Fumes: Burning solar components and materials can release hazardous smoke.

Grass/Brush Fires: Dry vegetation under panels increases fire risks. 

3. Site and Environmental Hazards

Lightning Strikes: The large, metallic, elevated surface area of the solar array makes the site more prone to lightning during storms.

Slips, Trips, and Falls: Uneven terrain, mud, and cables pose risks, especially in winter or wet conditions.

Weather-Related Illnesses: Exposure to high heat, causing dehydration, sunstroke, or heat exhaustion, is a major concern.

Wildlife and Livestock: Potential for venomous snake bites, spider bites, or insect stings. 

4. Mechanical and Maintenance Hazards

Moving Machinery: Risk of collision with maintenance vehicles, trackers, or automated equipment.

Mechanical Injuries: Hand tools, power tools, and unsecured equipment can cause injuries.

Falling Panels/Debris: Improperly secured panels or structural failure, particularly in windy conditions. 

5. Chemical Hazards

Cleaning Agents: Chemicals or detergents used to clean panels can contaminate the ground, necessitating proper containment.

Hazardous Materials: Older or damaged panels may leak toxic materials like cadmium or lead, though this is less common with new panels. 

6. Operational/Human Factors

Complacency: O&M technicians becoming too comfortable and overlooking dangers in an operating plant.

Ineffective Lockout/Tagout: Failure to properly isolate equipment before performing maintenance. 

Key Mitigation Strategies

Rapid Shutdown Systems: Required to reduce voltage within 30 seconds.

PPE & Tools: Use of CAT III/IV rated multimeters and arc-rated clothing.

Training & Safety Protocols: Regular training, adherence to O&M procedures, and, if applicable, using drones for inspection to reduce human exposure. 

For a 33kV line, minimum safe distances vary, but generally, expect at least 5.2 meters (around 17 feet) vertical clearance from the ground and a significant horizontal buffer for construction, often around 2.2 meters (7 feet) from poles, with larger distances (6-9 meters/20-30 feet) required for working near towers or with heavy machinery, and 10 feet (3 meters) is a common general safety practice for personnel. Always maintain a much larger distance for downed lines (35+ ft) and contact the utility company. 

Minimum Clearances (Varies by Region/Rule) 

Vertical (Ground): Around 5.2 meters (17 ft) for the lowest conductor, increasing with height or across streets (e.g., 6.1m/20ft).

Horizontal (Construction/Excavation):

Near Poles: ~2.2 meters (7 ft) for 11-33kV lines.

Near Towers: ~6 meters (20 ft) for 11-33kV lines.

For heavy machinery, larger setbacks (e.g., 9 meters/30 ft) are often mandated.

General Personnel: A common safety guideline suggests 10 feet (about 3 meters) as a minimum buffer. 

Key Safety Considerations

Downed Lines: Stay far away (at least 35 feet/10.7m) and call emergency services/utility company immediately due to dangerous ground currents (step potential).

Sagging: Lines sag, so clearance is reduced in the middle of spans, requiring extra caution.

Regulations: Local electrical safety standards (like India's Indian Electricity Rules) dictate specific clearances, so check local rules.
