Electrical diagnostics

  Includes breaker timing, contact resistance, and
full protection circuit validation (relays, CTs, and VTs)

  Confirms pickup levels, operating time, ratio, and polarity before a fault ever happens.  

Includes DGA, dielectric strength, oil factor (tan δ), insulation resistance, winding resistance, and excitation current tests.  

Surge, DC-hipot, and rotor-influence signals expose weak insulation or cracked bars while the machine is still on the floor.

Clamp-on and four-point tests confirm that earth grids, rods, and straps keep fault energy where it belongs, underground.

Protects personnel and electronics from touch voltages and lightning strikes.

New standby generators or UPS units are run at 25%, 50%, 75%, and 100% load to confirm voltage regulation, frequency stability, and automatic transfer, so your emergency power works perfectly the first time it’s needed.  

We log every voltage dip, imbalance, and harmonic up to the 50th order, then propose filters or capacitor tuning.

Cuts nuisance breaker trips, overheated drives, and inflated utility charges.

Ideal for: Facilities with large VFDs, arc furnaces, chillers, or photovoltaic inverters.

Suspect insulation fatigue or hidden rotor faults? We run surge, DC-hipot, rotor-influence, and partial-discharge tests up to 12 kV, spotting weak windings before they burn out.  

We stress-test LV/MV cables with VLF voltage, listen for partial-discharge clicks, and trend insulation resistance.

Flags aging joints and water-treeing early, so the only trenches you dig are planned.

Annual clean-and-lube, breaker timing, interlock tests, and panel IR survey.

Value: Extends switchgear life to 30+ years and keeps OEM warranties valid.

Degassing, dehydration, top-up, and silica-gel change on site.

Value: Maintains dielectric strength and prevents costly rewinding.

Bearing greasing, insulation-resistance trending, and exit-temperature checks.

Value: Predicts failure months in advance and schedules repairs for outages, not emergencies.
