The CT-8000 EHV Circuit-Breaker Analyzer is a fifth-generation design configuration. The Model CT-8000 is a standalone, microcomputer-controlled Circuit-Breaker Analyzer that is 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). The CT-8000 is available with either 3 dry contacts (CT-8000-3) or 6 dry contacts (CT-8000-6) configurations. Both models are supplied with 3 digital travel transducer input channels.
