Contact Resistance Testing	Measures resistance across main and arcing contacts using micro-ohm meters.	Ensures low-resistance paths; improves efficiency.
Insulation Resistance Testing	Applies high voltage (e.g., 5kV DC) to verify insulation integrity between phases and ground.	Detects moisture or degradation; enhances safety.
Timing Tests	Records open/close times with transducers to confirm operation within manufacturer specs (e.g., <80ms trip).	Verifies speed; complies with IEC 62271 standards.
Overcurrent Relay Calibration	Tests trip settings for long-time, short-time, and instantaneous protections.	Protects against overloads; customizable thresholds.
Air Pressure System Check	Inspects compressor, dryer, and pressure switches for optimal arc quenching.	Maintains interrupting capacity up to 50kA.
Functional Tripping Tests	Simulates faults to validate breaker response under load.	Confirms reliability in real scenarios.
Thermal Imaging	Uses infrared cameras to spot hot spots on busbars and terminals.	Prevents fires; non-invasive diagnostics.
Major Overhaul	Disassembly, cleaning, part replacement (e.g., contacts, springs), and reassembly.	Restores like-new performance; 5-10 year intervals.
Commissioning After Installation	Full testing post-installation, including primary injection for CTs/VTs.	Ensures seamless integration into systems.
