Transient voltage intelligent regulation device
Transient voltage regulator (DVR) is an advanced power electronic equipment. The equipment uses advanced power electronic semiconductor technology and control technology to ensure the safety of electricity consumption by combining the two technologies. DVR monitors the quality of power supply voltage in real time by using the internationally leading DSP/FPGA/CPLD control chips. When the voltage is detected to drop or surge, the regulator can instantly convert the power supply of the back-end equipment to the inverter, so as to ensure that the power supply of sensitive equipment at the back-end is not affected. The control and turn-off of the transient voltage regulator is controlled by software, and its typical switching time can be controlled within 1 millisecond to ensure the uninterrupted power supply of the device.

Zero line current eliminator is a unique product to control zero line current, but also for the distribution system three-phase imbalance, the third harmonic is too large new terminal comprehensive control device. It can not only eliminate the fire safety hazard of excessive neutral current, but also solve the complex power quality problem.
There are two reasons for excessive neutral current: Unbalanced three-phase harmonic current is too large and 3 times (mall shopping center is the most obvious), LED lights for power supply, switching power supply switch power supply, produce very big, due to 3rd harmonic current of power grids harmonic zero sequence current due to 3rd harmonic current, three-phase vector Angle is consistent, so three superposition of harmonic power flow to the zero line, three-phase unbalance current and flow to the zero line, zero line current is too large.
