Earth Integrity Testing
Earthing System Testing & Verification
A properly designed and maintained earthing system is the foundation of electrical safety. Earth integrity testing verifies that the earthing network provides a low-impedance fault current return path, limits touch and step potentials to safe levels, and ensures protective devices operate reliably during an earth fault.

Protection Relay Testing & Commissioning Services
The protection relay system is the last line of defence against electrical faults that can destroy assets and endanger lives. Green Watt's relay testing service covers commissioning, periodic maintenance testing, and post-fault investigation of protection relays from simple overcurrent relays to complex numerical IEDs.

Infrared Thermography for Electrical Infrastructure
Thermal imaging detects heat generated by resistance increases, overloaded conductors, loose connections, and failing components — before any visible sign of a problem. Green Watt's certified thermographers carry out thermal imaging surveys of HV and LV electrical equipment for utilities, industrial facilities, data centres, and commercial buildings across India.

On-Site PD Survey Services for HV Assets
Partial discharge (PD) is a proven precursor to insulation failure in cables, transformers, switchgear, and rotating machines — and it can be detected long before failure occurs. Green Watt's PD detection service surveys energised HV equipment in service, identifying and locating PD sources without any interruption to supply.
