CBA-2000 High Voltage Circuit Breaker Tester - I.S.A. - Altanova group
System for monitoring the basic parameters of medium and high voltage class circuit breakers. Tests oil, gas and vacuum circuit breakers in three-phase mode with six breaks per phase. The ability to install a microohmmeter into the device eliminates the need to use a separate device.The CBA-2000 installation is designed to monitor the condition of medium and high voltage class circuit breakers. The installation allows you to check the following parameters of the switch:
- timing characteristics of main and auxiliary contacts,
- currents of electromagnets on and off,
- speed parameters and contact travel parameters,
- contact resistance in static and dynamic modes,
- tripping of the switch at low voltage.
The unit can test oil, SF6 and vacuum circuit breakers.
Using an additional option, timing characteristics can be measured on a switch grounded on both sides, which makes work much safer for the operator and the device itself.
The CBA-2000 unit operates on battery power and mains power. It has a large LCD display on which you can evaluate and analyze the results. Test results are saved in the internal memory of the device. The device can work without connecting to a computer or with it, using free specialized TDMS software. The results can be printed on the built-in or internal printer.
TDMS software allows you to pre-define a test plan, analyze test results and generate a protocol. The program is compatible with all ISA test rigs. The circuit solutions used in the CBA2000 are designed for safe and reliable operation in harsh electromagnetic environments of medium and high voltage substations and power plants.
The CBA-2000 device in its basic configuration weighs only 13 kg, and with a built-in microohmmeter - 15 kg. Can be supplied in a shock-resistant plastic case at the request of the customer.
