CAT500 summarizes all our experience and knowledge in the design of circuit breaker testing equipment for the past 15 years.
CAT500 introduces some unique testing features and significantly saves the time required for condition assessment of all types of medium- and high voltage circuit breakers.
Features
CAT Modules provide measurement of main arcing contacts timing, static and dynamic resistance of AIS (Air Insulated Substation) circuit breakers with both sides grounded (BSG).
Timing measurements on a GIS breaker with both sides grounded is applicable for the most demanding cases for testing such as single-pole operated GIS CB which has a very low resistance of pole’s enclosures or where CT cannot be included in the measurement circuit between test access points.
Timing measurements on a GIS breaker with both sides grounded is applicable for the most demanding cases for testing such as single-pole operated GIS CB which has a very low resistance of pole’s enclosures or where CT cannot be included in the measurement circuit between test access points.
GIS Test Module consists of three isolated battery-based power sources used for the supplying of each pole of the single-pole controlled CB with a high current.
Test current is in the range of 400-500 A per pole (depending on the battery charge levels and resistance of the tested circuit).
Instead of the measurement of the changes of the current signal at secondary of the CT (when it is outside of grounding switches circuit), changes of the primary injected current will be monitored within the power source.
CAT500 is an advanced circuit breaker analyzer and timer designed for condition assessment of medium- and high-voltage circuit breakers. It combines timing, motion, vibration, static resistance, and dynamic resistance measurements in a single device, helping maintenance teams evaluate breaker performance efficiently.
CAT500 can be used for testing a wide range of medium- and high-voltage circuit breakers, including AIS (live and dead tank design) and GIS circuit breakers, three-pole and single-pole operated circuit breakers.
CAT500 reduces testing time by allowing simultaneous timing, static resistance, and dynamic resistance measurements through a single test setup. This minimizes wiring effort and enables faster condition assessment compared to conventional testing methods.
Yes. CAT500 can perform dynamic resistance measurement, which is a valuable method for assessing the condition of arcing contacts and detecting contact wear inside circuit breakers.
Simultaneous measurements provide a complete view of circuit breaker performance during a single operation. This helps engineers and technicians identify timing deviations, contact issues, and resistance changes without repeating multiple tests or reconnecting cables for different phases.
Yes. When used with CAT Modules, CAT500 can perform timing, static resistance, and dynamic resistance measurements on AIS (Live Tank) circuit breakers under both sides grounded conditions, improving safety and reducing test preparation time.
Yes. CAT500 supports testing of GIS circuit breakers, including challenging single-pole controlled GIS breakers under both sides grounded conditions through the use of the dedicated GIS Test Module
Yes. CAT500 records displacement, contact wipe, overtravel, rebound, damping time, and average velocity, helping engineers evaluate the mechanical condition of breaker operating mechanisms.
Yes. CAT500 includes vibration measurement capabilities that allow users to record and analyze circuit breaker vibration signatures for additional condition assessment.
The Minimum Trip Voltage test determines the lowest voltage at which a circuit breaker can successfully trip. This test helps verify the condition of trip coils, batteries, and control circuits.
CAT500 can measure up to 12 main contact chambers simultaneously, depending on the configuration and use of CAT Modules.
Yes. CAT500 is delivered with DV CB software application. DV-CB automatically generates reports including all asset-related information and performed tests. This gives you a comprehensive overview of the test object, test results and assessment. You can easily adapt test reports, for example, by choosing from different types of result tables and diagrams and by providing comments on every test. Furthermore, you can incorporate your company logo, photos and other test results.
