Checking at Site - Testing of Meter

The routine testing of meters should be carried out once in 3 years. Further, surprise checks should be conducted at the consumer's installation and meters should be checked from time to time. The significant points to be paid attention to although checking are given below.

Checklist of Important Points for Checking at Site

i) Connections of meter are proper.

ii) Seals are not tampered with.

iii) No loose or direct connections exist.

iv) Meter is not damaged to record less.

v) CTs are properly linked.  No reversal of any phase connection exists. There are multiplying factor is properly calculated and applied.

vi) Meter is well protected from rain, vermin's and dust etc.

vii) Links are connected.

viii) Terminal block is not damaged.

Along with the help of load current of known magnitude (preferably of resistive type) and a wrist watch having a second's hand, you could off hand check at site the performance of the meter as also its accuracy to a few extent.
