Motor protection MCHN02
Motor protection MCHN02
(OP)
all,
We have a conveyor which need to be changed its drive. From DOL starting 3.3 kV motor into VSD. This modification require additonal transformer 3.3/0.6 kV. The old motor is protected with MCHN02 motor relay protection. I want to ask for your help:
1. Anyone know where I can find the manual of this MCHN02? Google don't help me with this matter.
2. If This relay obsolete, could we re-setting this relay for the new protected transformer? or should we replace with the new kind of relay protection?
Thank you for your advice.
regards,
pamungkas

I thank for your information. I've contacted local rep of Areve and they have very quick respond. They also sent me the old manual of MCHN02. And you are right that it was obsolete and replaced by P220.
Related with our plan to change the DOL starting with VSD, which require new transformer, if I only concerned about ground fault may I STILL keep the MCHN02 (with new setting)in our system? I believe the motor characteristic just the same with transformer's. It is cheaper economically.
What is your suggestion?
