Wattmeter and Varmeter

Purpose

       Wattmeters and varmeters Ö42303 are intended for measureing of active and reactivecapacity in three-phase three-wire circuits of an alternating current by frequency 50 Hz and 60 Hz at uniform and non-uniform loading of phase.
       Wattmeters and varmeters are executed on the basis of the electronic converter of capacity in a signal of a direct current and the magnitoelectric device.
