Procedure for testing the meters on line |
| TOP |
Now in market the energy meters are available with indicating with all parameters, also we can connect sizable meter in PC so we can take the data on PC of all factory. |
| |
Meter are install for feeder consumption to record KWh units but now due to all parameters we can record all parameters of meter due to this we can find out what are the erratic parameter on feeder and we can rectify those parameters by modification. |
| |
Electric consumption are depend upon your healthy network system if your system are not healthy you can suffer extra electric consumption which are increase KWH |

| Why Energy Meter Testing Is Required? |
| TOP |
• The energy meter is heart of the power supply network
• If the energy meter is correct the consumption recorded and the billing is correct. If the energy meter is not correct we lose on all fronts.
• Therefore the energy meters are required to be checked tested and calibrated on regular intervals.
