Our AMC / Shutdown Maintenance Services Include:

⚡ HT Breaker Servicing & Testing Overhaul and test high-tension circuit breakers to ensure arc-extinguishing, insulation integrity, and mechanical performance.

🔁 Ring Main Unit (RMU) Servicing & Testing Inspection, cleaning, contact resistance checks, and gas pressure verification of SF6 or vacuum-type RMUs used in medium-voltage networks.

🔌 LT Breaker Servicing (ACB/MCCB) Mechanical servicing, contact polishing, insulation resistance testing, and trip unit calibration for Air Circuit Breakers and Moulded Case Circuit Breakers.

🧪 Secondary Injection Testing Accurate simulation of faults to test trip logic and response of protection relays inside ACBs and MCCBs for reliability and safety.

⚙️ ATS (Automatic Transfer Switch) Servicing Inspection, cleaning, and functional testing of ATS panels to ensure automatic and smooth switchover between EB and DG supply during outages.

🔋 Transformer Servicing & Routine Testing Oil testing, IR & PI measurements, bushing inspection, and core tightness checks for distribution and power transformers.

🛢️ Transformer Oil Filtration On-site filtration, dehydration, and purification of transformer oil to restore dielectric strength and remove moisture, sludge, and dissolved gases.

⚙️ HT/LT Panel Servicing Complete servicing of switchgear panels including breaker compartments, busbars, CT/PTs, control wiring, and insulation tests.

🔍 Relay Testing – Primary & Secondary Injection Testing protection relays using both primary and secondary injection methods to validate pickup current, time delay, and coordination.

🌍 Earth Pit Maintenance Earth resistance measurement, chemical earthing check, watering, and refurbishment to maintain a safe and efficient earthing system.

📦 Busduct / Riser Servicing & Testing Inspection, joint resistance testing, cleaning of busbars, and thermal scanning of busducts and vertical electrical risers.
