Switchgear Analyser (SA 100)
The Switchgear Analyser (SA100) is an essential substation preventative maintenance tool and aid for power utilities with ever increasing demands for more reliable low cost energy and on-time maintenance.

Possible test results which can be computed per phase for each breaker operation include:
  • Peak Coil Current
  • Current Pulse Length
  • Operate Times (Main / Resistive)
  • Operate Time Spread (Main / Resistive)
  • On Time
  • Dead Time
  • Datum Velocity
  • Velocity at Contact Touch
  • Stroke
  • Contact Length (Main / Resistive)
  • Contact Separation
  • Travel Overshoot
  • Rebound
  • Mechanism Times (Pre Latch / Latch Period)
  • Fingerprint Comparison on all channels (Grey Zone Checking)
  • Battery Voltage
In addition, Dynamic Timing of up to 2 breaks per phase is made available with 6 x 20A constant current outputs.

The SA100 can optionally perform timing of up to 12 main and 12 resistive contacts per phase when combined with the SA112 expansion unit.
