Control Panels

Control Panels

Control panels generally provide circuit control via relays or through a microprocessor-based system, monitoring and/or supervision of equipment. Control panels can incorporate instrumentation, control switches and indicator lights or graphic terminals. Like Motor Control Centres, Control panels can also be used to accommodate motor power circuits, variable speed drives and distribution circuits.

All control panels are manufactured in accordance with BS EN 61439-2.

Transformer / Generator Panels

All protection and control panels are manufactured in accordance with BS EN 61439-2. TCS has vast experience of protection and control systems.

PROTECTION

TCS can implement circuits for transformers, generators, busbars and electrical machines which are associated with protection.The protection installed on an industrial power system has to cope with more difficult conditions than the protection of any other kind of power system.Variable fault levels, altering switching arrangements and large motors may all impact on the protection relays fitted and settings required. Conventional (electromechanical and static) relays have been used successfully for separate protection functions and in more recent years micro-processor based multifunctional relays are becoming universally popular as they provide almost unlimited flexibility in protection applications.
