Electric energy meter verification instruments are widely used in power, metallurgy, chemical, tobacco, textiles, railways, ships, properties and other industries.For the power metering department, the electrical meter error verification was performed on the spot without disassembling the meter and the power stop, and the inspection of the stealing electrical violations of the electricity inspection department provided a convenient solution.

Electric energy meter verification instrument price
The price of TY-6A single-phase electric energy meter is about 3,500 yuan.TY550 single -phase power meter on -site inspection device price is around 2800 yuan.The price of high -electric GDSXC three -phase multi -functional power meter is about 12,000 yuan.Shi Xu SX681 Multifunctional Sanxiang Electric Teter Verification Device price is around 1,1600 yuan.
Principle
When the electrical meter inspection device is connected to the measured circuit, the current coil and voltage coil have a cross -current current. These two interlaced currents generate in the iron core.The magnetic flux passes through the aluminum disk and induces the vortex flow in the aluminum disc; the vortex is rejected in the magnetic field, so that the aluminum plate is turned (active torque) and rotates.The greater the power consumption of the load, the greater the current of the current coil, and the greater the vortexy in the aluminum disk, the greater the torque of the aluminum plate rotation.That is, the size of the torque is proportional to the power consumption of the load.
