AL107 CVT/EVT voltage mutual inductor tester
Performance standards:
DL/T963-2005.
Feature:
1, the large black and white LCD screen LCD display, even in strong sunlight can clearly show that a large Chinese character operating the menu prompt;.
2, the integrated structure, light weight, easy to carry;.
3, the instrument can also measure the CVT ratio and the change of electromagnetic voltage transformer and the transformer ratio;.
4, variable ratio CVT test, the test voltage is high, direct output voltage 10kv, 10kv to be completed over a variety of voltage transformer turns ratio and the angle difference measurement function;.
5, apparatus, controlled by a single chip, high accuracy, test speed, the data accurate and reproducible;.
6, anti erroneous connection of 380V power supply protection, erroneous connection of 380V when the input power supply, automatic protection equipment alarm;.
7, the instrument can store 28 groups of test results, to record the date and time of test.
