HT Panels are manufactured by many companies. Sometimes there is an existing panel of a particular make and a new panel of another make has to be installed, an Adapter Panel is used to couple the two different types. This is so because the placement of busbars is different for different panel designs. Thus Adapter Panels are used to couple the two different types.
Control and Relay panels are used when a particular panel has to be operated from a different position like a separate common room, either for convenience or due to extreme weather conditions.
Applications:
Used in power distribution for controlling and protecting lines, substations and transformer and distribution substations, transformers, rectifier units, capacitor banks etc
Thanks to SF-6 AUTOPUFFER breaking technique, they do not generate over voltages and are therefore highly suitable for retrofitting, upgrading and enlarging older installations where the insulating materials of the cables and apparatus may have been stressed during service.
