CAT250 series inherited all capabilities and experience collected from market leading CAT Advanced series.
CAT250 introduces unique touch screen interface designed to significantly save the time required for test preparation and results analysis of all types of medium- and high voltage circuit breakers.
Test results could also be printed on the 112 mm (4.4“) thermal printer (optional accessory) in tabular and graphical form.
The CAT250 series circuit breaker analyzers & timers can be coupled with DV Power Coil Analyzer SAT II series to create one test system (control and testing done with CAT250 touch screen interface) capable to perform the following list of applications:
Built-in micro-ohmmeter (optional) provides high current for dynamic and static resistance measurement, as well for BSG timing measurement of dead tank circuit breakers.
The additional six voltage analog channels have four selectable voltage ranges available (±1 V, ±5 V, ±60 V and ±300 V AC/DC). They are used to monitor:
Three vibration channel inputs record circuit breaker vibration fingerprints providing non-invasive assessment of the circuit breaker main contacts using vibration-based analysis.
Three transducer channels provide measuring displacement of the circuit breaker moving parts, contact wipe, over-travel, rebound, damping time and an average velocity. Either an analog or a digital transducer can be connected to these universal channels.
Test results are printed on the 112 mm (4.4 inch) thermal printer (optional accessory) in tabular and graphical form.
CAT250 is a circuit breaker analyzer and timer designed for comprehensive condition assessment of medium- and high-voltage circuit breakers. It performs timing, motion, vibration, coil, single phase static and dynamic resistance measurements (up to 500 A), within a single platform.
CAT250 features a modern 10.1-inch touch-screen interface that simplifies test setup, execution, and result analysis. The intuitive workflow helps reduce testing time and improves efficiency in the field.
CAT250 can simultaneously measure up to 12 main contacts, including pre-insertion resistor contacts, as well as up to 6 auxiliary contacts, making it suitable for the most advanced circuit breaker configurations.
Yes. With the optional built-in micro-ohmmeter, CAT250 can perform single phase dynamic resistance measurement, allowing engineers to evaluate the condition of arcing contacts and identify wear-related issues.
Yes. CAT250 can be equipped with an optional built-in single phase micro-ohmmeter capable of generating up to 500 A DC for accurate static resistance measurements.
CAT250 measures displacement, contact wipe, over-travel, rebound, damping time, and average velocity of circuit breaker moving parts using dedicated transducer channels.
Yes. CAT250 offers vibration measurement capabilities that record vibration fingerprints, enabling additional non-invasive assessment of circuit breaker condition.
The First Trip test evaluates the performance of a circuit breaker after a long period of inactivity. It helps identify mechanical issues, increased friction, or problems within the operating mechanism.
Yes. CAT250 can measure and record coil currents, coil voltages, and coil resistance simultaneously for up to three coils during opening and closing operations.
Yes. An optional Minimum Trip Voltage module allows users to verify the minimum voltage required for reliable operation of opening and closing coils according to international standards.
Yes. CAT250 supports Both Sides Grounded testing of AIS circuit breakers through an optional BSG feature, improving safety and reducing preparation time in substations.
Yes. CAT250 features a robust design, integrated touch-screen operation, optional thermal printer, internal test plans, and DV-CB software support, making it ideal for field maintenance and diagnostic testing.
