WAI Transformer Handbook _FINAL_2.24.26_Flipbook Version

Single-Phase Pole-Mounted Transformer

*Completely Self-Protected or CSP means the transformer contains a re- settable secondary circuit breaker to clear low voltage faults, primary isolation link(s) to isolate the transformer core in the event of an internal failure, and appropriate lightning arrestors. Conventional transformers require external fusing and lightning arrestors.
