- Transformer
This type of transformer is a 20 kV transformer type CSP with a capacity of 50 KVA. It says the CSP transformer is short for Completely Self-Protective. This transformer has a safety arresster to secure a direct lightning strike and induction and lightning surge that propagates through the power grid. Equipped with tap changer so that the transformer voltage on the secondary side can be arranged so as not to happen voltage drop or over voltage.

There are actually three types of insulators. Namely type pin type, post type and suspension type. The photo on the side is a pin type. The use of the insulator is to withstand the lithric flow of the network so that no short circuit occurs, either between the network or by grounding (earth / earth).
