Product description
Product parameters
Reference standard: DL474.5-92, DL/T987-2005.
Features:
● It is suitable for use in lightning arresters with power, power outage or laboratory;
● The current and voltage sensors are completely isolated and safe. Really achieve three-phase current, three-phase voltage test at the same time, improve work efficiency; support single-phase test or two-phase test at the same time, easy to choose;
● Support three-phase voltage or B-phase voltage reference signal sampling mode; support no-voltage mode, find the voltage reference through software calculation; also select the induction board mode to find the voltage reference through the B-phase induced electric field intensity;
● Anti-interference calculation can be performed to compensate for the phase-bias of the two-phase currents of A and C.
