Vanguard CT-7000 Digital Circuit Breaker Analyzer

The Vanguard CT-7000 is a portable circuit breaker analyzer for testing the timing and mechanical performance of high voltage and extra high voltage breakers. It gives maintenance crews and test engineers the data to confirm a breaker will operate as designed when a fault occurs.

Key Features

Contact and motion analysis: measures main and resistor contact time, stroke, velocity, over travel, bounce back, and contact wipes
All breaker operations: analysis on OPEN, CLOSE, OPEN-CLOSE, CLOSE-OPEN, and OPEN-CLOSE-OPEN operations
Flexible timing windows: selectable 1, 10, or 20 second windows, to suit fast trip operations or longer sequences
Multiple contact channels: the current CT-7000 S3 is available with 3 or 6 contact timing channels, and earlier versions were offered with up to 12
Digital travel transducer inputs: three channels covering linear travel of 0.0 to 60.0 in and rotary travel of 0 to 360 degrees
Built-in breaker initiation: can operate the breaker directly, with a 30 A, 250 Vac/dc maximum initiate capacity
PC software included: Windows based breaker analysis software comes with the purchase for reviewing, storing, and reporting test results
Optional extras: transportation cases, on-line timing mode, dual ground testing mode, and a Bluetooth interface

Typical Applications

Commissioning tests on new circuit breakers
Routine preventive maintenance and diagnostics in substations
Troubleshooting slow, sticking, or misaligned breaker mechanisms
Verifying insertion resistor operation on EHV breakers
Trending breaker performance over time for condition based maintenance

Why Choose It

A breaker that fails to interrupt current quickly can cause severe often catastrophic damage to the electrical system. The Vanguard CT-7000 combines timing, travel, and velocity measurement in one portable field ready instrument so you can catch mechanical problems before they become failures
