Introduction on Different types of Circuit Breaker Tester
1.0 Introduction
The CT-6500 is the fifth generation microprocessor-based, digital time travel circuit breaker tester developed by .Amperis Products SL. 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.
This circuit breaker tester includes the conventional Time-Travel test mode that 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 circuit breaker tester 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.
