Next we have been transfered to metering department.Tn.Haji Azmi asked us to follow the technician to go to home by home to placed the meters.
He explained a little bit about metering unit.
Meter is a device to measure the electricity sold by the electric utility company.
it is also used to measure the electric energy passing through various parts of the generation, transmission and distribution systems.
There are 3 types of meter:
a)Single-Phase Low Voltage Meter
b)Three-Phase Low Voltage Meter
c)Current Transformer Meter (CT Meter)
Maximum Demand
Metering Requirement
< 10 kVA
Single phase, two wire 240V
10 kVA < X < 45 kVA
Three phase, four wire 415V
45 kVA < X < 500 kVA
Three phase, four wire CT meter 415V
Generally, supplies to domestic premises are given at single phase. However, TNB does provide three phase supply where the load requirements justify it.
check out the address!
CT meter : use digital electronic meter
capacitor band
main switch
the old one: meter electromechanical
the new one: meter electronic
A box for neutral wire connection between TNB supply and the contractor’s wiring for the house. Rated current for neutral link is 60A and 100A.
