i am in need of a full panel meter compliment for a generator in need of voltage , amps or watts , and freq i havent had any luck finding these even at grainger , i can find the voltage but not the amps or watts with the current xformers and such
As sue asked:
What size generator is this for?
Additionally, 3ph?
What voltage? Do you need PTs?
For larger generation (>500kw), the protective relays already supply half (or more) of the metering circuits, and the costs of downtime are generally killers, so one tends to spec meter quality such as templdl and jdsmith suggested. But if you are equiping a 20kw - 100kw, and downtime is inconvenient, but not horribly costly, the budget could easily be a limiting factor.
Taking a hint from you are looking at Grainger, try Newark, Allied, Mouser, digikey. They should have package CT and meters.
Watt meters are going to be a bit more difficult. If the appliction is single phase .... okay, to many variables. Need some more data.
One other issue. If you are looking to mount analog panel meters to a panel fixed to a small generator frame, They have a habit of shaking themselves to needle-sticking art objects - often rather quickly.
(edit - added thought)
I bought an ammeter (and CT) and a freq meter for an off-grid house gen a few years ago from the local commercial small gen store. Not a seller of the Generac stuff - rather, this guy had Listers and the like, packages as well as bare gensets. He had basic instruments, volt, amp, cts, freq in his counter- didn't have pf or kw for single phase.
