Improvement In The Leading Phase + Lagging Phase Reactive Power
In addition to the reactive power of the lagging phase, it can also improve the reactive power of leading phase through the control of shunt reactor. Minimizes the power cost caused by the leading phase power during the nigh time and light loading time zone.

Optimum Design At The Industrial Field
It adopts 7“ color touch LDC panel and Hangeul menu as the basics, it enhances the visibility and is best for the industrial field in Korea.

HSVC Effect Of Installation

General SVC

As the supply of leading phase reactive power is limited to three types of 20kvar, 40kvar and 60kvar, there is the limit in the control of power factor.
The power factor fluctuates between 0.71 and 0.95.
The step type compensation is made for the power factor.

Hybrid SVC [HSVC]

As the supply of the lagging phase reactive power is segmented to 5 kvar units from 5 to 60 kvar and 12 compensation steps, it minimizes the reactive power fo the load.
The power factor is constantly kept at 0.95.
The power factor compensation is close to the linear form.

Leading Phase Reactive Power?

It is the reactive power generated when the current (loading impedance: XC > XL) which has the phase leading to the voltage due to the capacity of the load (C) flows. Though it is not related to the energy consumption like the lagging phase reactive power, it increases the capacity of the distribution/ transmission line and power generation equipment.

[ Except from aritcles pubished in Hangukilbo Newspaper ]

For the energy saving, more LED lighting systems are used. But due to the use of low-class LED product, there is the increase in the power cost due to the lagging phase reactive power.
