Output Cable Length

[ndeepak]

How does output cable length affect the performence of VFD?

Hello ndeepak

 

The length of the uutput cable contributes to the capacitive loading on the VSD and this effects the switching losses in the inverter. If the cable length is too long, the inverter will be overloaded by the switching current and this can cause the inverter to indicate earth faults etc.

Additionally, the length of the output cable can result in standing waves being generated and this can have an impact on the voltage at the motor terminals. If there are standing waves generated, the motor can be damaged.
