This protective equipment is used at 11 kv sub-station .the main load bread break switch (lbs) mechanism is available for 630a and the over current protection scheme is done through HRC fuse. The panel includes 3 numbers of CT (current transformer) and 2/3 numbers of pt (potential transformer) for measuring system current and voltage respectively and 3 numbers of HRC fuse for protection of overload. The scheme is so designed that if fault occurs in any panel also includes 3 numbers of ampere meters and one number of voltmeter with selector switch for monitoring system current and voltage. The standard panel size is 900x 900x1800mm and weight is 450 kg.
