Overview

Reactors (for series ...R execution)

The dry type resin embedded reactors are specially designed to suit the reactive power compensation application. Their exceptional linearity and thermal stress resistance characteristics ensure a high reliability degree even in case of temporary overvoltage.

Contactors
Contactors for automatic capacitor banks are specially selected for their excellent handling capability during endurance tests. A key feature of the contactors is a special configuration (e.g. a front-mounted contact block) ensuring the serial insertion into the circuit of damping resistors limiting current peak on energizing of the capacitor bank. This connection also ensures capacitor pre-charging in order to limit the second current peak occurring on closing of the main poles a few milliseconds later.

Ventillation
Except for series 100 systems, all capacitor bank are equipped with a ventilation system specially selected for their duration longevity. The capacitor bank ventilation system consists of  fans with temperature-dependent probes which provide the fans with the necessary thermal data. In case of temporary overheating, the capacitor bank is automatically deactivated.
