in the EPGK-F ?
General Information:
EPGK-F is designed to test the mechanical dynamic characteristics of vacuum, SF6, with oil and etc high voltage and low voltage circuit breakers.

  • ♦ Auto identify open or close status. To give correspondent close or open prompt according to channel’s status.
  • ♦ Can detect and prompt connection status of 6 channels (12 channels is for option), it’s convenient to detect connection.
  • ♦ 100 groups data storage.
  • ♦ Large LCD 320×240, can read clearly even in direct sunlight.
  • ♦ Friendly English interface, easy to operate.
  • ♦ Graphical analysis function, to realize waveform and measuring processed data to displayed at same screen.
  • ♦ Delay protection, auto switch off coil voltage after breaker acting, to protect breaker and HV tester.
  • ♦ Open-closed test by auto or manual is selectable.
  • ♦ High/low voltage test is all available. Auto seeking the lowest opened or closed voltage.
  • ♦ Re-closed testing, could test closed-open, open-close, open-close-open and etc parameters.
  • ♦ Build-in thermal printer.
