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.
