10 equipment you MUST recognize in every distribution

Distribution Transformer. The distribution transformer is a main and largest equipment of distribution substation. It is basically a static electrical device which steps down the primary voltage of 33kV or 11 kV to secondary distribution voltage of 415-440 volts between phases and 215 volts between phase and neutral through delta-star windings by electromagnetic induction without change in frequency. Circuit Breaker. The circuit breaker is an equipment which automatically cut off power supply of the system when any fault or short circuit occurs in the system. Lightning Arrester. Lightning arrester is a most important protective device of distribution substation to protect valuable equipment as well as working personnel. Air Break (AB) Switch / Isolator. Air break switches are used to isolate equipment for maintenance and also for transfer of load from one bus to another.
