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.
