Performance Tested
Every Keystone product goes through rigorous quality checks and testing procedures before it leaves our plant. Our wide range of quality checks are both in-process and prior to shipment. Standard procedures include point-to-point checks of wiring diagram s and continuity checks on all wiring. We routinely perform schematic logic, device functionality and wiring tests before we ship to you. Our Doble F2100 test set, Peschel 100KV Hi Pot and our custom breaker simulator are applied to critical components. All relay acceptance, high voltage and functional testing procedures are conducted according to IEEE/ANSI standards.
