Operator Safety
The CableData Collector is designed to detect partial discharge sources in High
Voltage (HV) cables. If no discharges are detected this does not necessarily imply
that an item of HV cable is discharge free. Discharge sites often have dormant
periods and insulation structures can fail through causes other than those attributable
to partial discharges. If discharges of considerable magnitude are detected in plant
that is connected directly to the high voltage power system, the authority responsible
for the plant should be notified immediately.
The CableData Collector is designed for use at ground potential only.
When testing electrical plant ensure that the metalwork is earthed before taking any
measurements.
Adhere strictly to local safety procedures.
Do not make measurements when there are electrical storms in the vicinity.
Do not make measurements immediately following the energisation of a circuit.
Do not disturb plant during measurements either mechanically (e.g. By shaking or
striking it), electrically (e.g. by increasing the voltage) or physically (e.g. by applying
heat).
Do not operate the instrument or its accessories in an explosive atmosphere.
