Compound structure, main compartment is of flameproof type connection compartment is of increased safety type. Modular design, each circuit can be combined freely. Built-in high breaking mini circuit breaker or molded case circuit breaker, can be controlled on-off via handle on encl...
relays. Protective relays continuously monitor these parameters: voltage, current, and power; and if these parameters violate set limits they generate an alarm or isolate that particular circuit. These types of relays are used to protect equipment like motors, generators, andtransformers, and so on...
The excessive flow may lead to the breakdown of wire and stops the flow of current. The fuse can be replaced or changed with the new one with suitable ratings. The fuse can be made up of the element like zinc, copper, silver &aluminum. They also act as a circuit breaker which is ...
circuit breaker tripping circuits, etc. The primary side of the transformer is connected to the high-voltage circuit and the instrument or other circuits are connected to the secondary winding. Any number of instruments can be connected to the secondary until the total impedance does not exceed th...
The transmission substation contains equipment used to sectionalize the electric transmission system when a fault or short circuit develops on one of the circuits. Circuit breakersin the transmission substation are used to switch generating and transmission circuits in and out of service. The faulted ...
