D164 three-phase wattmeter

Also, this device can be called: D-164, D 164.

D164 three-phase watt-hour meter is a high-impact shield splash-proof device ferrodinamicheskoy direct-reading system.

Power meters are designed to measure active power in three-phase alternating current at 50 Hz.

Dimensions - 160×160 mm.

Accuracy class - 2,5.

Shock, vibration, resistant to shaking.

Wattmeters D164 characterized by high mechanical strength and are used for installation on ships and mobile installations.

Specifications D164:

Rated current (including a current transformer with a secondary current of 5 A) - 5 A to 6 kA.

Measured power (depending on the rated voltage)

- 127 V (including myself) - from 1 kW to 1200 kW;

- 220 V (including myself) - from 2 kW to 2500 kW;

- 380 V (including voltage transformer through 380/127 V) - from 3 kW to 4000 kW.
