DESCRIPTION
Impulse generators are designed to locate faults in power cable by the high voltage impulse method, in which a high-voltage impulse is transmitted down the cable to cause the fault to arc. The arcing fault is then pinpointed using an appropriate impulse detector. Megger impulse generators may also be used to perform voltage versus time acceptance tests, or to burn faults that fail to break down under impulse to reduce their resistance.
APPLICATIONS
Megger impulse generators pinpoint faults on primary distribution cable rated from 3.3 to 35 kV, including directed buried cable and cable in conduit or duct.
For faults that do not break down in the impulse mode, a burn mode is provided to reduce the resistance so that those faults will break down under impulse voltage.
In addition to fault locating, these units can be used as proof testers to check the quality of insulation before and after cable repair.
FEATURES AND BENEFITS
Impulse generators offer specific benefits that ensure efficient, effective and safe fault locating.
