Introduction
Weis is a specialist company with over 20 years of experience in the
commissioning, testing & maintenance of switchgear and power network
fault monitoring within the Power Utility Industry.
Based on its successful SA100 Switchgear Analyser, Weis has developed
a Reduced version (SA100 ’R’) with fewer channels providing
a lower cost robust switchgear test set for performance analysis on high,
medium and low voltage circuit breakers.
Breaker Test & Analysis software is an essential 32-bit Windows™
database program that provides an easy to use operator interface for configuring
& displaying the SA100 ’R’ test results in graphical and
text report formats.
BTA software runs on a standard IBM compatible PC with a 32-bit Windows™
operating system. This permits the transportation of test records to a
regular office based or portable computer.
The display and printing of a report can be fully customised to include
logo’s, in-house styles, text phrases and results format, thus eliminated
the need to manually complete a written form in most cases.
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)
