D342 phase meter three-phase

Purpose and Scope
D342 phase meter is a panel instrument ferrodinamicheskoy direct-reading system designed to measure the power factor in three-phase circuits AC, 50 Hz with a uniform load phases.

D342 is manufactured to specifications of the TU-OPP.533.026 number M-53 and is designed to operate in ambient temperatures from - 15 to +35 ° C and a relative humidity of 80%. Phase meter D342 is used for mounting on boards of power plants, substations and other electrical power stationary type units.

Main technical characteristics
1. The type D342 Phase meters manufactured for direct inclusion in the circuit with a voltage of 127, 220 or 380, and also to include a current transformer secondary current with the power of a 5 and a voltage transformer with the value of the secondary voltage 100V.
2. Scale of the device is marked in cosφspredelami 0,5-1-0,5 (capacitive and inductive shift).
3. Accuracy class 2.5. Basic error in its normal temperature, rated voltage and frequency does not exceed ± 2,5% of the length of the scale.
4. Change readings caused by change of ambient temperature by 10 ° C from a normal side or the other does not exceed ± 2,5% of the length of the scale.
5. Changing the readings at a frequency change of ± 5 Hz from the nominal shall not exceed ± 2,5% of the length of the scale.
6. Changing the readings when the voltage of ± 10% of nominal shall not exceed ± 2,5% of the length of the scale.
7. Arc length scale of 125 mm, working part is the whole area of her testimony.
8. Settling time is less than 4 seconds.
9. Isolation test voltage of 2 kV AC 50 Hz.
10. Instrument weight 2.5 kg.
