GKC433A Switchgear Analyzer

Circuit breaker Testing



GKC433A Switchgear Analyzer
 
1) GKC433A is used for testing electrical and mechanical characteristic of high voltage circuit breaker, disconnector and contactor.
2) Measure the time parameters (close, open, asynchronous, bounce) of 12 main contacts. Measure the co-operate time between 6 main- and 6 auxiliary contacts.
3) Measure the pre-insert time and resistance of 6 resistor contacts
4) Setting with 12 contact state indicator lamps on panel. It is easy to judge close and open state.
5) There is one analog input channel. Measure the travel, over-travel, rebound, overshoot and speed of the breaker by using resistance transducer.
6) Operate Close, Open, O-C-O, O-C, C-O control sequences.
7) Test the mechanical characteristic operated by CB manually.
8) Create and store 50 speed definitions of circuit breakers. Users can recalculate the speed by a new definition after save the results.
9) Built-in regulately DC control power output. Setting with manual voltage regulate knob, opening button and close button. It can used for action voltage testing.
10) Built-in DC/AC current sensor for measuring close and open control current.
11) Built-in DC output for motor driving.
12) Using IGBT electronic switch for control outputs, with high precision and long life age.
13) Can store 500 test results in memory. Loss of power without loss of data.
14) The stored data can be transferred to USB disk.
15) Using an USB disk to update the tester software.
16) LCD displays the operation interface, test data, contacts, travel and current curves.
17) Thermal printer can print test result fast, include contacts, travel, and current curves.
18) Max 1000 times action testing automatically.
19) Use an USB cable connecting to Windows PC to operation.
20) Open and analyze data on PC, generate report and print A4 report.
21) Chinese and English interface selectable.
