In the power system, there will be a lot of battery DC power supply devices (including battery, charging device, DC power supply, etc.) in power generation enterprises, transmission stations (substation, converter station, series supply station, communication station) and other departments. The continuous operation of these devices ensures the stability and safety of the power system.

In the process of equipment installation and debugging, maintenance personnel carry out daily evaluation, operation and maintenance of power transmission and transformation equipment. Multi-functional testing instruments are the guarantee to improve work efficiency. Common test scenarios for power equipment:

1, DC or AC power supply voltage, current, power amplitude, waveform, power factor and harmonics;

2. Whether the protection of charging equipment starts normally when the output current exceeds the limit;

3. Battery capacity test;

4. Voltage and current stability accuracy of charging equipment;

5. Whether the voltage fluctuation and ripple coefficient of DC bus exceed the standard.
