CAT 500 - Circuit Breaker Analyzer & Timer

Circuit Breaker Analyzer & Timer CAT 500 Series

CAT500 summarizes DV Power’s experience and knowledge in the design of circuit breaker testing equipment for the past 15 years.

CAT500 introduces unique testing features and significantly saves the time required for condition assessment of all types of medium- and high-voltage circuit breakers.

Features:

• Simultaneous timing, static resistance, and dynamic resistance measurement on up to 12 main contact chambers under BSG conditions by use of CAT modules.
• Saves testing time by single cable connection and simultaneous measurement.
• Timing, motion, and vibration measurement.
• Minimum trip voltage (MTV) test.
• Graphical 10.1” touch-screen color display provides easy control of the test device and results analysis.

CAT Modules provide measurement of main arcing contacts timing, static resistance, 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 are applicable for demanding testing cases, such as single-pole operated GIS circuit breakers with very low resistance of pole enclosures, or where the 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 supplying each pole of the single-pole controlled circuit breaker with a high current. Test current is in the range of 400-500 A per pole, depending on battery charge levels and resistance of the tested circuit.

Instead of measuring changes of the current signal at the secondary of the CT when it is outside the grounding switches circuit, changes of the primary injected current are monitored within the power source.
