Protection Studies / Testing & Commissioning

The testing and commissioning of high voltage electrical equipment is a highly specialised activity. With every HV electrical installation or fault finding, our skilled engineers carry out their specified area of work to the highest technical and safety standards.

Our range of high voltage commissioning services includes:

  • Dissolved Gas Analysis (DGA), SF6 Sampling
  • HV Protection Grading and Testing
  • AC pressure testing
  • HV Cable Sheath Testing
  • VLF Cable Testing
  • Earthing Studies
  • Cable Fault Location
  • Partial Discharge
  • Insulation Testing
  • DC Cable Testing
  • Thermographic Inspections
  • DC Pressure Tests up to 33kV
  • Overcurrent and Earth Fault Relays
  • Directional Overcurrent and Earth Fault Relays
  • Transformer Testing

Cables are subject to damage; we can carry out a series of tests to identify and locate the fault, then carry out the necessary repairs as required.

Transformer testing is crucial for mitigating the risk of operating failure. Due to its static nature, the power transformer can be regarded as a very reliable unit. Nevertheless, there is a possibility of failure because of internal faults as well as being subjected to stresses from external sources which could cause the internal fault condition.

Progen offer Earthing Studies, HV Grading Studies and HV Protection Testing Studies. We will determine the required settings to ensure that your equipment has the right protection settings. That way any fault is managed correctly and power distribution assets will be safe during use and if a fault occurs.
