Sample ac voltmeter and ammeter wiring diagram
Sample ac voltmeter and ammeter wiring diagram
(OP)
hi to everybody,
I plan to install ac voltmeter and ammeter on a 3 phase, 3-wire main dist. panel using transformer rated current voltmeter and ammeter to monitor current (amps) demand on the system. Can anybody please direct me to a URL or links that has sample wiring diagrams showing the connection to potential and current transformers.
Further, can I use the 2 nos. CT's presently serving the kilowatthour meter?
any help will be very much appreciated.

RE: Sample ac voltmeter and ammeter wiring diagram
If it is a listed panel, you may void the listing by installing additional meters/equipment in the panel. Otherwise, if you already have the meters, the mfg. should have wiring diagrams...if not, try SATEC, Bi-Tronics, or Electro Industries websites for info.
"Further, can I use the 2 nos. CT's presently serving the kilowatthour meter?"
You can if they are yours and you do not over burden them. If they belong to the utility, I seriously doubt they will allow you to connect to them.
You could also purchase a 3 wire power meter and get kW and kVAR along with the amps and volts.

Also recommend shorting switches for the ct circuits and disconnects/fusing for the voltage inputs if you don't already have them.
Is it an analog or digital display? Who is the mfg. and what is the catalog number/type of meter?
