Test Schedule - Meter Testing
The test schedule as per the Central Electricity Authority Regulations on Installation and Operation of Meters is given below.
Table: Test Schedule
Meter Type
Schedule
Single Phase LT meters
Once in 5 years after installation
LT three phase meters (CT operated) 20 kVA to 100 kVA
Once in a year to be checked since these are installed for high value consumers
Other LT metering systems
Once in two years after installation
EHT / HT meters
The testing schedule for HT consumers should cover the whole Metering System involving CTs, PTs and Pilot Wire. Detailed ratio testing of CT, PT and control Pilot/ wires is to be completed. Testing by mobile vans/mobile cubicles through secondary injections kit and phantom loading might also be carried out through Measurement Unit. All new meters should meet the needs of Accuracy Class spelt out in Table.
Table: Requirements of Accuracy Class
Type of Consumer
Overall Accuracy Class
EHT Consumers (33 kV)
0.2
HT Consumer (44 to 33 kV)
0.5 or better
LT Consumer (Whole Current meters)
1.0 or better
LT Consumers (CT operated)
