Power Factor Correction Capacitors

Optimize Energy, Enhance Efficiency, Create a Green Future

To meet the electrical energy demands of modern industries and businesses, we proudly introduce Power Factor Correction Capacitors that adhere to the International Electrotechnical Commission (IEC) standard 60831.

The Power Factor Correction Capacitors are widely applicable in industrial, commercial, and public sectors. Whether in manufacturing, construction, or the energy sector, our products assist you in efficiently managing energy consumption, reducing system losses, and thereby saving costs.

Why power factor is more than just a number──The importance of power factor.

Simply defined, power factor is a way to measure the efficiency of an electrical system. Expressed numerically, power factor is the ratio of working power to apparent power, with the ideal calculation represented as 1.0. Numbers aside, the most critical thing to recognize is that a load with a power factor of 1.0 results in the most efficient operation. However, many industrial and commercial electrical systems have a lower power factor, which means organizations are not fully utilizing the electrical power that they’re paying for. In these instances, additional energy is needed to operate the load, requiring the utility to provide more current. This additional power translates to fees and/or penalties levied by utility providers to customers with three-phase services; residential customers are never penalized.

When system efficiency is improved, it reduces the amount of energy that is required from the utility, which in turn can lower or eliminate costly penalties and fees. One of the most simple and cost-effective ways to achieve this is by installing power-factor-correction capacitors.

General Description:

Power Factor Correction Capacitors are suitable for low-voltage power systems with a frequency of 50Hz or 60Hz. They are primarily used to improve power factor, reduce reactive power loss, enhance grid quality, and maximize transformer capacity, among other benefits.
