Protection Relay Test Sets

Protection relay test sets, or relay testers, verify relays and microcomputer protections by simulating complex transient, permanent, and conversion faults. This is done to ensure a power system's reliability and safety during installation and commission. These devices typically test single-, three-, four, and six-phase protection relay systems.

ATEC stocks both manual and automated protection relay test sets from industry leaders such as OMICRON, Doble, and more.
