1.0 Introduction
The CT-6500 is the fifth generation microprocessor-based, digital time travel circuit breaker
analyzer developed by Vanguard Instruments Co. The CT-6500 can fully analyze a utility circuit
breaker’s performance by measuring: the contact time, stroke, velocity, over-travel, bounce-back
and contact wipe.
The circuit breaker contact motion analysis includes: Open, Close, Open-Close, Close-Open
and Open-Close-Open operations. A timing window of one second, ten second or twenty second
can be selected. The ten and twenty second windows allow timing of long timing events such as
circuit switcher contact activities.
The conventional Time-Travel test mode allows the user to fully analyze the circuit breaker
contact time and contact travel information. Additional circuit breaker information such as:
Operating-coil current reading, breaker DC coil power supply voltage reading are also
available.
The CT-6500 is available with the following configurations:
CT-6500-3:
- Three Contact-Input channels
- Three Digital Travel Transducer Input channels
- One Analog Voltage Monitor Input channel
- One Digital Voltage Monitor Input channel
- One Trip/Close Current Monitor channel
CT-6500-6:
-
Six Contact-Input channels
- Three Digital Travel Transducer Input channels
- One Analog Voltage Monitor Input channel
- One Digital Voltage Monitor Input channel
- One Trip/Close Current Monitor channel
CT-6500-12:
-
Twelve Contact-Input channels
- Three Digital Travel Transducer Input channels
- One Analog Voltage Monitor Input channel
- One Digital Voltage Monitor Input channel
- One Trip/Close Current Monitor channel
There are two different modes of operation for the CT-6500 which are Stand Alone Mode and
Computer Control Mode. The manual will focus on the Stand Alone Mode. The Computer Control
Mode is covered under the Circuit Breaker Analyzer Software Series 2 manual.
