CELLS:

  • Switch: Operation + Measurement of installed and spare fuses.
  • Circuit breaker: Operation + Testing of protective tripping thresholds by primary injection
  • Circuit breaker: Testing of protective tripping thresholds by secondary injection
  • Testing of coil, motorisation on/off tripping thresholds.
  • Testing of contact synchronisation.

TRANSFORMERS:

  • On-load low voltage measurements: voltage, current, harmonics, active power, reactive power and apparent power.
  • On-load thermographic inspection.
  • Resistance measurements on primary and secondary windings.
  • Insulation resistance measurement between primary windings and earth

LV CIRCUIT BREAKERS:

Recording of tripping time.

Verification of values measured according to manufacture specifications.

CAPACITORS:

  • Full power review of the LV network associated with the capacitor.
  • Voltage, current, power, harmonics.
  • Measurement of efficiency of each step.
  • Capacitor selection: Type, power, etc.
  • Help

CRYOGENIC CLEANING:
Efficient, ecological cleaning

Dry ice blasting is a stripping method that uses small, compact balls of dry ice as an abrasive material.
