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. |

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 |
