  • Earthing System Health Assessment

    Earthing is used to protect you from an electric shock. It does this by providing a path (a protective conductor) for a fault current to flow to earth. It also causes the protective device (either a circuit-breaker or fuse) to switch off the electric current to the circuit that has the fault.
    Elegrow Technology can help you in
  • Establish minimum earthing risk assessment design criteria.
  • Verify if a sufficiently low impedance is available to facilitate satisfactory protection operation under fault conditions.
  • Verify if a protection of personal and equipment in the vicinity of the electrical equipment are not being exposed to unsafe potentials under steady state or fault conditions.
  • Verify that system voltages are within reasonable limits under fault conditions and to verify that insulation breakdown voltages are not exceeded.

  • Partial Discharge Testing

    Partial discharges (PD) are small electrical sparks that occur within the insulation of medium and high voltage electrical assets. Each discrete partial discharge is the result of an electrical breakdown of an air pocket within the insulation. These discharges erode insulation and eventually result in insulation failure.
    Elegrow Technology Partial Discharge Testing can help predict future performance and reliability of critical assets, including:
  • Cables, splices, and terminations
  • Power transformers and bushings
  • Switchgear
  • Motors and generators
