Product description
Product parameters
  Reference standard: SD109-1983.
 
  Features:
  ● Distributed wireless synchronous measurement of volt-ampere phase isoelectric parameters, wireless synchronous measurement of six-channel voltage amplitude phase, single-phase or three-phase measurement of secondary voltage drop, automatic calculation of ratio difference, angular difference;
  ● It can be used as a secondary load online tester and a three-phase volt-ampere phase when used alone;
  ● It has the function of resisting harmonic interference, and still maintains measurement accuracy in the case of harmonics;
  ● Current amplitude phase measurement can be as low as 1mA. It is very suitable for substation main transformer load test and new station or small station current measurement.
