The verification regulation of electric energy metering device and relevant technical regulations have provisions on the errors caused by the voltage drop in the secondary circuit of the voltage , which must be measured accurately and quickly. ZC-105C transformer secondary voltage drop and load tester is developed to adapt to these characteristics.

It has these product characteristics:

1.Three-phase three-wire, three-phase four-wire and single-phase automatic measurement; With automatic range switching function to ensure the accuracy of testing;

2.Electronic principle circuit combined with DSP technology makes the test stable and strong anti-interference ability;

3.After the measurement is completed, various parameters related to load are automatically calculated for the convenience of customer analysis and test;

4.Large LCD display of Chinese characters, all operations are prompted by Chinese menu; Data has power off storage and browsing function, and can transmit data online with computer;

5. For the second load test, the clip-type ammeter is adopted to sample the current, and there is no need to disconnect the secondary circuit. Online measurement without power failure can be achieved. Automatic switching range: during the measurement process, the measurement accuracy and display digits can be guaranteed by switching to different positions according to different values of test objects.
