HV testing (proof/insulation testing)

Used to prove the integrity of (and identify and confirm) fault conditions in cable networks. The variable output voltage can also be used for sheath testing at 5 or 10 kV.
 

Proof/burn

Following a breakdown of the cable under test, a high current is applied that stabilizes the fault condition. This can assist pre-location and pinpointing of unstable faults.
 

Pinpoint fault location

Accurate pinpoint fault location is achieved using the acoustic method, whereby the powerful 8/16 kV 1500-joule surge generator (thumper) and an acoustic receiver (Megger MPP2000) is used.
