Transformer - Probability of Failure without Arresters
Transformer - Probability of Failure without Arresters
(OP)
All,
I have been asked to look into the probability of Main Power Transformer (230/35kV) failure should one be implemented without high side arresters. The thought process behind this is to figure out the affect of energizing a transformer without an arrester due to lead times of the arresters, and install the arresters once they arrive.
Any leads will be greatly appreciated.

Transformers are critical transmission assets and due to their complex design they are also very susceptible to over voltages. Surges entering the winding can cause part winding resonance, and a flashover between phases or to earth. The flashover of the winding dielectric insulation usually causes irreparable damage. In most cases the transformer will need to be replaced.
