Product Overview: Vanguard CT-7500 Digital Circuit Breaker Analyzer – Discontinued

Vanguard CT-7500

This product has been discontinued see CT-8000 S3

The Model CT-7500 Series 2 is a stand-alone, microcomputer-driven EHV Circuit-Breaker Analyzer. It’s inexpensive and easy to use. It operates in either of two modes: as a traditional Time-vs-Travel analyzer or as a Quick-Shot (on-line timing).

 

In the Time-Travel mode, the CT-7500 analyzes breaker performance: contact time, stroke, velocity, over-travel, and wipe. Contact-motion analysis includes: Open, Close, Open-Close, Close-Open, and Open-Close-Open. The timing window is selectable: 1-second, 10-second, or 20-second periods. The 10-second and 20-second windows allow timing of long-duration events (e.g., circuit-switcher contacts).

  • On-Line Timing
