Installation of Meters and Verification of Connections
Apart from testing and calibrating the meters they must be properly installed as per the links diagram. The points in which must be kept in view although meters are installed are given below.
Installation of Meters
a) Position of meter should be such in which reading is simply visible.
b) Mounting of meter should be on solid wall or DP structure or on panel board.
c) Vertical mounting of meters should be ensured. The utility engineer should use a plumb bob and mark a vertical line prior to installation. He could also use a spirit level and put on the top of the meter after hanging on the screw hole. Instead, he should put spirit level on the edge of the terminal block to ensure vertical mounting.
d) For HT metering equipment, CTs should be right on the incoming side before the point of isolation.
e) The meter box should be sealed.
f) The meter recording should be checked at site.
