Capacitor based systems:

Capacitor Based Power Factor is the simplest and most cost-effective way to correct lagging power factor.

The unit looks at the power usage of the site, and then switches in capacitor banks to compensate for the reactive loads on the site. This is a fairly coarse solution, operating usually in increments of 12.5 or 17kVAr, and switches within 30mS of detecting a change in reactive loads. These systems are ideal for sites with motors or pumps that run fairly consistently.

If you need faster acting Power Factor Correction, such as when a motor is brought under load quickly, for example a sawblade at a sawmill, we can change the contactors on the capacitors to Thyristor switches, these switch much faster than traditional systems and can create a quicker reaction time.
