Product introduction

Power supply by large capacity lithium battery, not only can protect the system security and also can be compared to an instrument to provide clean power to avoid the on-site power interference, to ensure accuracy.

Alternative name

Secondary voltage drop tester, PT secondary voltage drop tester

The Characteristics of the products
1. Can realize three phase three wire, three phase four wire and single test.
2. Use industrial plastic case, strong and durable, ensure the safety of the test personnel and system.
3. Can auto shift the measurement range, ensure the accuracy.
4. Electronic circuit combined with DSP technique, good stability and strong anti-interface ability.
5. Auto calculate all the parameters refer to load after finished the test, convenient customers to analyze and test.
6. With LCD, menu operation, the test results can be stored after power off, can transmit the data connect with computer.
7. Use high capacity 7.2V11Ah lithium battery as power supply, no effect to loop, prevent the protection of the system. It also can be used if there was not power supply source on site.
8. Auto shift the measurement range: shift to different position according the test data during the test, ensure the accuracy and display.
9. Working time up to 24 hours (longest), can test under charged state.
10. With deft charger, convenient to measure, can connect with external charger to test if low power.
11. Small in volume , light in weight. 
12. Wide secondary current / voltage measurement range. Can analyze the resistance and impedance of 1mΩ, test  the online actual load of S degree CT (secondary rated current is 5A) when the working current is 50Ma. Can analyze the conductance and susceptance of 0.001mS when the working voltage is 5V.
13. Can store 480 groups test results, can save for 10 years after power off. 
14. With LCD and RS232 communication interface.
