High voltage electrical discharge illuminates the sky, showcasing the immense power of lightning as a natural electrical phenomenon 1. Introduction Lightning arrestors (LAs) are critical protective devices used in electrical substations to safeguard equipment from high-voltage transients caused by lightning strikes and switching surges. Installed at strategic points such as transformer terminals, incoming feeders, and busbars, LAs provide a low-impedance path to ground for the surge voltage, thereby protecting insulation and preventing equipment failure. Typically, metal oxide varistor (MOV)-based arrestors with zinc oxide discs are used due to their excellent non-linear voltage-current characteristics and fast response time. The construction includes a weatherproof porcelain or polymeric housing, internal ZnO blocks, and grading rings to control electric field distribution. The design and application of lightning arrestors in substations are governed by standards such as IEC 60099-4 , IEEE C62.11 , and IS 3070 (Part 3) , which specify performance requirements including discharge capability, residual voltage, and energy absorption. Regulatory frameworks such as CEA Technical Standards for Construction of Electrical Plants and Electric Lines Regulations  and CEA Grid Connectivity Regulations  emphasize the mandatory installation of lightning protection systems to ensure grid reliability and safety. 2. Why Monitor LA Leakage Current? 2.1 Benefits of Leakage Monitoring Early Fault Detection : Rising resistive current indicates degradation of ZnO elements. Prevention of Equipment Failure : Prevents catastrophic failures that can damage adjacent equipment like transformers or CTs. Uninterrupted System Operation : Online test—no need to shut down the system. Data Trends & Predictive Maintenance : Enables data logging and future condition forecasting. Enhanced Safety : Alerts to impending arrester failures, reducing risks to personnel. Cost Savings : Reduces forced outages and unscheduled maintenance. 2.2 Drawbacks of Not Testing Undetected Degradation : ZnO block aging remains invisible in total current readings. Unplanned Failures : Leads to collateral damage and unsafe operating conditions. Inefficient Maintenance Planning : Unable to prioritize replacements or maintenance scheduling. Non-compliance with Regulations : Risk of penalty and liability under CEA regulations. 3. Regulatory Framework and Standards 3.1 International Standards IEC 60099-5: Recommended Practices for Monitoring of Surge Arresters in Service Clause 7.2.3 : "The measurement of the resistive component of the leakage current should be done using the third harmonic analysis or voltage peak method."

CEA Draft Guidelines on Type-Test Validity (2024) Lists lightning arresters among major equipment requiring periodic health assessment and compliance to type-test schedules. 4. LA Leakage Current Test Methods 4.1 Third-Harmonic Resistive Leakage Current Method (IEC 60099-5, Method B1/B2) Test Setup Clamp-on current transformer (CT) placed on the earth lead of the arrester. Optional field probe near the arrester to detect harmonic voltage. Procedure Connect CT and field probe securely. Begin online test; arrester must be energized. Record total leakage current. Isolate 3rd-harmonic resistive component using internal algorithms. Apply correction for harmonics, temperature, and system voltage. Compare results to accepted thresholds. Record, report, and trend the data. 4.2 Voltage-Peak Method (IEC 60099-5, Method A1) Procedure Connect voltage reference probe (typically from PT secondary). Measure leakage current at the voltage waveform's peak. Determine resistive component from peak amplitude. Correct and analyze data against benchmarks Interpretation of Test Results Leakage Current (µA) Condition Action Required < 350 Normal Continue in service 350–500 Degrading Monitor periodically > 500 Critical Immediate removal required 6. Safety Precautions During Testing Ensure testing is done by qualified and trained personnel. Verify all test equipment is calibrated and in good working condition. Always wear appropriate PPE including insulated gloves, face shield, and arc-flash suit. Confirm that the arrester is properly earthed and test point is accessible. Maintain safe distance from energized parts during testing. Use insulated tools and rated CT probes. Confirm environmental safety (no water logging, slippery surfaces, or risk of accidental contact). 7.
