restoration the following tampers with date &time
and also log of the event |
| |
|
Missing potential |

Sealing and locking arrangement |
2 sealing screws on the meter cover& 2 sealing
screw on terminal cover are provided.Separate
sealing arrangement are provided for MD reset
button& optical port
|
| 24 |
Type of communication |
Data can be transferred to and fro from aCmRI
conforming to CBIP-111 through optical port
conforming to IEC-1107 provided in front of the
meter.data can also be transferred through central
based computer using GSPMS lines and suitable
modems.The data element size and its overhead
speed of transmission should less than 10
minutes. |
| 25 |
Others |
Meter should record energy correctly |
| |
|
i) in case of Current reversal |
| |
|
II)In case of neutral fail |
| |
|
iii)In case of neutral disturbance |
| |
|
iv) Meter should record at Imax in any tamper
event due to magnatic influence |
| 26 |
Real time Clock |
Time drift of Real time clock in the meteris less
than±7 minutes per years |
