Title: Early-Time (E1) High-Altitude Electromagnetic Pulse Effects on Trip Coils.

Abstract

A High - Altitude Electromagnetic Pulse (HEMP) is a potential threat to the power grid . HEMP can couple to transmission lines and cables , causing significant overvoltages which c an be harmful to line connected equipment . T he e ffects of overvoltages on various types of power systems components need to be understood. HEMP effects on t rip c oil s w ere tested and presented in this report . A high voltage pulser was built to replicate the induced voltage waveform from a HEMP. T he pulser was used to test breake r trip coils with increasing pulse magnitude s ranging from 20 kV to 80 kV . T he State - of - Health of each trip coils was measured via mechanical operation and impedance measurements before and after each insult to identify any damage or degradation to the trip coils . Dielectric breakdown was observed at the conductor leads during testing , causing the HEMP insult to be diverted to the grounded casing. Ho wever , the dielectric breakdown did not caus e interfere ne w ith regular device operation .
