Product Features
1. It can realize three-phase three-wire, three-phase four-wire and single-phase automatic measurement.
2. Use engineering plastic chassis to meet the durability and effectively protect the safety of testers and systems.
3. The company's secondary load online tester has an automatic range switching function to ensure test accuracy.
4. The use of electronic principle circuit combined with DSP technology is to make the test stable and resistant to interference.
5. After the measurement is completed, the parameters related to the load are automatically calculated, which is convenient for customer analysis and testing.
6. A large-screen Chinese character LCD display is used, and all operations are prompted by the Chinese character menu; the data has power-off storage and browsing functions, and can be used to transfer data online with the computer.
7. The large-capacity 7.2V11Ah lithium battery is used for power supply, which does not have any impact on the test circuit and avoid system protection. At the same time, it is used when there is no power supply on site.
8. The secondary load test uses a clamp ammeter to sample the current without disconnecting the secondary circuit. Can achieve online measurement without power failure. Automatically switch the measuring range: according to the test during the measurement process
The different values of the object are switched to different positions, so that the measurement accuracy and the number of display digits are guaranteed.
9. The working time can be up to 24 hours (the longest), and the measurement can be done in the charging state.
10. A light-weight charger is attached for easy measurement, and can be measured with an external charger when the battery power is insufficient.
11. The secondary load online tester is small in size and light in weight.
12. Very wide secondary working current / voltage range. Under the working current of 50mA, it can distinguish the resistance and reactance of 1mΩ, and can test the S-class current transformer with a secondary rated current of 5A
On-line actual load; at a working voltage of 5V, it can distinguish the conductance and susceptance of 0.001mS.
