AC Vacuum Interrupter Dielectric Test Set - Model HVA-40/10™ Download Product Brochure - PDF

Slideshow

The HVA-40/10 model has been designed specifically for testing vacuum interrupters in accordance with ANSI / IEEE C37.60. The test set provides up to 40 kV with respect to ground, at test currents up to 10 mA.

AC Vacuum Interrupter Dielectric Test Set Features
  • Compact design
  • Zero-start interlock
  • "Dead-man" switch for safety
  • 40 kV with respect to ground
  • Tests to ANSI C37.60 specification
  • Voltage measured at output of test set
  • High speed fault detector and cut-out
  • Continuously adjustable output voltage

The test voltage is smoothly adjustable over the full range and is accurately monitored at the output of the high voltage transformer. A milliammeter indicates the leakage current.

A large HV-ON lamp and a complete set of status indicators give the operator full control of the test set and the item under test.

A high speed solid state cut-out disconnects the voltage on breakdown or flash-over and actuates the red “failure” indicator. The HVA-40/10 instrument is equipped with a “dead-man” safety switch requiring two hand operation of the instrument. A “zero-start” interlock prevents the application of high test voltage on start-up. The test can also be used for many applications where AC dielectric testing is required such as: Switchgear, insulators, wire & cable, oil, rubber-gloves and many more.
