Product description
Product parameters
  Reference standard: JB/T5356-2002, JB/T5357-2002.
 
  Features:
  ● Supports detection of CT and PT (protection, metering class 0.2S, TP class) steady state and instantaneous parameters;
  ● Adopt advanced DC detection principle, the equivalent excitation voltage is up to 30kV;
  ● Unique one-button all detection and sub-test detection function, more flexible and convenient on-site use;
  ● Automatically give the inflection point value according to the procedure;
  ● Automatically give 5% and 10% error curves.
