High Voltage AC Withstand Tester for Cables 50 kV

Portable AC high voltage test set applying power-frequency withstand voltage to insulated cables. Used in cable factories and utilities for routine and type voltage tests.

Specification

A regulating transformer, high voltage transformer and measuring divider apply a smooth voltage ramp to the cable core. Leakage current trips the set within milliseconds on breakdown, protecting the operator and the instrument.

Features
