Power calibrators
Single phase and three phase power calibrators generate voltage up to 500V and current up to 120A with programmable phase angle.
They are useful for checking three phase measuring equipment: meters, converters and protective relays. Can be used as phantom load or meter test bench for checking electricity meters on the site
They are able to programing harmonics, interharmonics, shapes and timing signals what is useful for checking network quality analysers
