Testing of power system protection

Current source PWPN-1

DESCRIPTION

Device PWPN-1 generates sinusoidal current or voltage with power frequency and controlled amplitude. It is equipped with ammeter/voltmeter.
User can choose generated and measured variable (current or voltage) by two-position switch, selected variable is indicated by LED (A or V).

PURPOSE

Current source type PWPN-1 is designated for checking current transformer load, measuring sensitivity of current protection devices etc.
