VSD Cracking and Smoke presence
VSD Cracking and Smoke presence
(OP)
Hi I got this issue occur during the first power on of the vsd there is a cracking then smoke comes out from the device then breaker trip. What could be the possible reason why this issue occur. It could be earth to phase short or IGBT/Thyristor as well.

There could be lots of reasons but one thing is certain. It's stuffed.

One thing you can do now however is to confirm the presence or absence of any major misapplication or installation error, for example the wrong voltage or a grounded connection. Beyond that, you replace the unit and start over, send the burned unit to the manufacturer for a Root Cause Failure Analysis (RCFA).

Take a look at the electrolytic capacitors for obvious damage.
