Product Description

Multi-function CT PT Analyzer CT/PT Protecon Calibrate Tester

Desription

GDHG-108A CT/PT Analyzer supports test voltage method to test bushing CTs which installed on
 transformer or inside switch-gear, suitable for the laboratory and on-site detection. Can be easily 
and conveniently done voltage current characteristic, transformer ratio, ratio and phase angle
error, load test items on CT/PT.

Features

Main Functions and Features

  • Adopts the voltage detection principle, convenient for on-site detection of transformer bushing CT.
  • To meet the requirements of GB1207, GB1208, GB168-47 (IEC60044-1.6) and other standards.
  • Supports the detection of CT and PT.
  • No external auxiliary equipment, a single machine can complete all test items.
  • With high speed micro printer: real-time print the test data and characteristics curve.
  • Adopts intelligent controller, operation is simple.
  • All day long large LCD screen, full English menu and interface, graphical display interface.
  • Automatically given CT/PT (excitation) knee point value.
  • Auto display 5% and 10% error curve.
  • Save 3000 groups data, it won't lost after power off.
  • With USB port. The data can be saved in USB disk and read by PC(WORD format file). 

Products Features

  • The use of "one key shuttle" shortcut operation, more powerful, more superior performance, more convenient to use.
  • Real-time display test data and dynamic plotting curve, the graph reading is more clearly.
  • European handle quick connector, lock design, large contact surface, strong current flow ability.
  • The built-in closed quick plug, non shielding design, safe and reliable.
  • The built-in  full power supply, strong load capacity, the current cable can be extended.
  • Using a pressure injection molding engineering plastic box, solid and reliable.
  • Block type structure of overall unit, dispersive stress; shock-absorbing treatment, to ensure the reliability of transportation.
  • Small and light≤18kg, is very conducive to the field test
