The on line timing mode can detect a breaker s operating conditions with little or no down time In this mode the first trip operation time of the breaker is captured If a breaker has been in service for a long period of time and sitting in close position the first trip time of the breaker may be slow possibly due to a sticky mechanism The on line mode is very useful in such cases because traditional breaker timing may not detect this condition since several operations may have occurred before the first timing test is conducted Diagnostic Capabilities The DigiTMR S2 can perform diagnostics on its internal electronics Diagnostics can performed to verify contact cable connections and to test the travel transducer s electronics Open Close Coil Current Monitoring A built in Hall Effect current sensor records the circuit breaker s operating coil current amplitude and duration The circuit breakers operating coil waveforms effectively a performance fingerprint or current profile can be used as a diagnostic tool for analyzing a circuit breaker s performance Internal Test Record and Test Plan Storage The DigiTMR S2 can store up to 200 test records and 100 circuit breaker test plans in Flash EEPROM A test plan comprises of all circuit breaker performance specifications Stroke Velocity and Contact Time When a test plan is used the DigiTMR S2 compares the test results for the circuit breaker against its performance to gen
