High quality Lafaelt capacitors and detuned reactors can make sure long-term stable and reliable operation of the device.
Equipped with an interface to communicate with PC to realize distribution network automation.
It can realize fast real-time tracking and display of power factor, bus voltage and protection action signals.
High-voltage reactive power compensation devices are widely used in public utilities and large industries and mining enterprises in recent years. In a high-voltage system, the first step is to maintain the voltage at a certain level, at the same time it is necessary to compensate for the reactive power needs on the equipment side to reduce losses, so that customers can meet the relevant requirements proposed by the power supply department.
The hv devices are mainly used to improve the power factor of the grid, support system voltage, and suppress harmonics, reducing the harm of harmonics to the system.
High quality Lafaelt capacitors and detuned reactors can make sure long-term stable and reliable operation of the device and the design has a long service life.
Equipped with an interface to communicate with PC to realize distribution network automation.
It adopts the advanced automatic monitoring and control devices, always ensuring that the power factor of the compensated equipment is above 0.92, exempting fines caused by insufficient reactive power.
Equipped with a comprehensive monitoring and protection system, it has the function of monitoring, displaying, and protection fundamental voltage and current, and specialized anti resonance capability.
It can realize fast real-time tracking and display of power factor , bus voltage and protection action signals.
With perfect protection functions: quick-break protection, over-current protection, over-voltage and under-voltage protection, three-phase current imbalance protection.
