T Type Automatic Capacitor

up to 64.8 kVAr

The Type T enclosure provides a smart compact unit with ample room for connection and maintenance

A suitably rated door interlocking main isolator, switch-fuse or circuit breaker can be incorporated

The units are available with multi stage switching with on / off / auto switches and indicator lamps if required

Supplied completely assembled and designed to enable simple straight forward installation

Highly reliable, low loss capacitors with self-healing properties

Safety protection system incorporated in each capacitor element

Soft Switching contactors for minimal system disturbance

Available with standard or slimline enclosures for wall or floor mounting and with top or bottom cable entry

Construction
The capacitor and control gear are housed within a robust steel enclosure which is suitable for either wall or floor mounting as well as vertical stacking.

Control Gear
The equipment incorporates a special soft switching contactor arrangement to minimise system disturbance which is caused by capacitor switching. For example, a 50kVAr automatic step is controlled by two contactors switching in cascade. These contactors incorporate a pre-connection resistor system which reduces the effect of current inrush, thus reducing system disturbance and increasing product life. 100 Amp circuit fuses are installed to protect each 50kVAr capacitor step and its associated control gear. On / off / auto switching can be included if required.

Capacitors
The capacitor unit comprises the requisite number of individual capacitor elements. These elements are manufactured from impregnated metallized polypropylene and have a self-healing capability. Each element incorporates a fail safe protection device.
