Abstract
An arc flash validation system that detects incident energy produced by an arc flash is disclosed. The arc flash validation system comprises one or more power transformers (PT) and current transformers (CT). The voltage and current outputs from the PT and CT may indicate the incident energy of an arc flash. The PT and CT outputs may be stored in system memory. The arc flash validation system may analyze the stored data and compare the stored data to a predicted hazard level to generate a relay-event report.
