Analog voltmeter EQn SWT Series

stationaryACammeter

They are an ammeter for measuring the current in each phase of a 50-60 Hz three-phase line. Three-phase voltmeters are used for measuring the voltages between phases, or phase-phase and phase-neutral in a line. They incorporate a switch in order to select the wires between which the measurement is desired. The EQ..n SWT also has a position of disconnection in the switch (OFF). They indicate the rms value of the voltage, even with high harmonics, with a minor influence on the accuracy. Please indicate on order if instruments are connected directly (max. 10 A),or to a current transformer. In this case, please indicate ratio of current transformer). Electrical data Overload capacity according to DIN 43780 Continuously 1,2 times rated value Short duration 2 x UN 5 s voltmeters The setting time is approximately 1 minute. Moving iron Moving coil with rectifier system in the ammeter, self-shielding movement, withcore magnet. They use hairsprings for the creation of the restoring torque,and pivot suspension with spring-loaded jewel bearings for vibration andshock resistance Scales 90º scale with coarse-fine division. Scales are practically linear
