Meter not running right?

Guide for meters used with instrument transformers

The problem is:	Try this:
No reading	Check Current Transformer (CT) short circuiting devices. They may be open. Be sure the meter is getting voltage. Verify correct polarity on all CT's. Verify at least 5% rated current on CT's.
Low reading	Look for 1 or more CT closed short circuiting device. Verify correct polarity on all CT's. Be sure voltage and current to each stator is from the same phase. Check register reading. Both last and present.
Present reading lower than last	Look for reversed polarity on CT's or PT's. If disk rotation is OK, verify register readings. Maybe usage has not yet caught up with last month's too high reading.
