INVERTER SYSTEM AND METHOD OF DETECTING STATE OF POWER CABLE OF THE INVERTER SYSTEM |
| 摘要 |
Provided is a method of detecting a state of a power cable of an inverter system. The method includes obtaining a value of a phase current supplied to a motor through the power cable according to a preset period, generating a mobile window having a certain size with respect to a phase-current value obtained for each period and obtaining a mobile window operation value by using the phase-current value included in the generated mobile window, comparing the obtained mobile window operation value with a preset reference value, and detecting whether the power cable is abnormal, according to a result of the comparing. |
