Power factor correction capacitors

LV-transient-free static switching capacitor

The Eaton LV-transient-free static switched capacitor bank provides next-level power system enhancements. This level of protection is ideal for high-current loads that rapidly switch on and off – such as those found in rock crushing, arc-welding, plastic injection moulding and crane applications – which are typically vulnerable to power factor issues, voltage flickers or require sag or harmonic corrections. Eaton’s transient-free static switching device comes in two models: the FTA model and the FTE model.

A fast, transient-free system

The FTA model of Eaton’s transient-free, statically switched capacitor bank can compensate any load within 1–4 seconds. These models contain three independent control modes – power factor control, voltage control and load sharing – and an integrated, three-phase network analyser to measure all power parameters and current harmonics to the 63rd harmonic.

A real-time, transient-free system

The FTE model of Eaton’s transient-free, statically switched capacitor bank includes all the features of the FTA model but can be used to compensate extremely rapid loads within one cycle of operation, typically 4–20 milliseconds.
