Thanks for appreciation

Sir
Default setting is : 0.015 of In hai.
Aap default setting rakh sakte h koi problem ni h

Etasmart8t k common me ac volt denge ya dc volt

[@eeebackbenchers]

Brother 8R - means you have to use normal cap duty Contactor
And 8T means it’s designed for thyristor
Use only when you have thuristor

Hello sir
how to slove UNDC

[@eeebackbenchers]

Sir
Undc means under current , means there is no sufficient current from ct
Check ct output secondary current at Apfc ct terminals and car polarity

[@ShairAliDar]

OCOM aur UNDC alarm ki setting kaise karna hai. Kaunse menu main Jana hai

[@eeebackbenchers]

As per my best knowledge , I think there is NO option in AFPC Menu to change UNDC(under current ) setting .
Secondly this is mandatory protection which update you that there is some issue in current input.

[@ShairAliDar]

mujhe UNDC ka threshold change karna hai. kya aapke pass apfcr ki koi manual hai? @@eeebackbenchers

How to solve UNDV (alarm) problem

[@eeebackbenchers]

Simply means undervoltage : check voltage level and ensure the rated voltage at defined terminals

[@mvvdprasad6691]

RMS line to line voltage worg voltage show disply why problem

[@eeebackbenchers]

Verify voltage level at APFC terminals & ensure connection should be done as per manufacturer recommendation.

Ithd alarm aa raha hai

[@eeebackbenchers]

Current harmonics is higher than 25%
You should you detuned reactor or do harmonics study on your plan for better result

2500/5 ki ct h undc fault h to 0.015---0.5 me se kya seting hogi
