FAQ
Q: How to choose the model number?
A: Please specify the system rated voltage,frequency, harmonic current situation etc. If you do not decide, please advise your detailed problem for us to give you a solution.
Q: What is the standard packaging?
A: 1*manual(or electronic manual)
1* plywood carton
Q: Why should we consider harmonic current content?
A: In the application,there are harmonic current more or less. If the capacitor is not matched with the reactor under the harmonic current,the capacitor will be damaged easily.
Q: How to choose capacitor for new-building demand?
A: you can consider from several sides like the below sample.
System Voltage | Harmonic current content | Reactor Detuning rate | Rated Line Voltage | Electrical Wiring | Capacity |
0.38kV | none | - | 0.45kV | 3 phase compensation △ wiring | Cylindrical≤40kvar Entangle ≤50kvar |

3times and above | 14% | 0.525kV | |||
5times and above | 7% | 0.28kV | 3 phase unbalance compensation Y wiring | Single phase≤20kvar Three phase ≤30kvar | |
3times and above | 14% | 0.3kV |
