General Information: 
EPGK-H is designed to test the mechanical dynamic characteristics various voltage degree vacuum, SF6, with oil and etc high voltage and low voltage circuit breakers.
 
Features:  
  • ♦ 8.4 inch large color LCD, can read clearly even in direct sunlight.
  • ♦ Friendly English interface, touching key, easy to operate.
  • ♦ bsp;Build-in printer.
  • ♦ Integrated power supply, suitable for on-site test. DC30-280V adjustable power source, current 20A. The active voltage value of open/close coil can be set arbitrarily, the low voltage action of circuit breaker is also can be tested.
  • ♦ Universal type velocity sensor, easy to install.
  • ♦ All the data and graph can be available only by one time switching.
  • ♦ To be suitable for all kinds of GIS, SF6/vacuum/oil switchgears.
  • ♦ 6000 groups data storage (memory card is extendable). Built-in clock to save the test date and time.
  • ♦ USB port, to save the data to the U disk.
  • ♦12 channels metal contactors, three channels closing resistance measurement.
  • ♦ Built-in anti interference circuit, suitable for 500kV substation reliable testing.
