Weis is a specialist company with over 40 years of experience in the commissioning, testing & maintenance of switchgear and power network fault monitoring within the Power Utility Industry.

Based on its pioneering of analogue timing techniques developed over more than 20 years ago, Weis has applied its expertise to develop a robust switchgear test set for performance analysis on high, medium and low voltage circuit breakers.

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
• Spring Compression on Vacuum Contacts
• Travel Overshoot
• Rebound
• Bounce Time
• Mechanism Times (Pre Latch / Latch Period)
• Acceleration
• 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.
