GDCR-602 Re-firing Circuit Breaker Instrument
1.1General introduction
GDCR-602 Re-firing Circuit Breaker Instrument is designed to test the vacuum circuit breakers which be used to switch capacitor groups.
It records three phase and neutral point voltage and three phase current of capacitor groups in high frequency
when vacuum circuit breaker open and close capacitor to the grid.
The tester can inspect whether there is a reconnect procedure when circuit breaker open the connection of
capacitor and grid. If there is a reconnection the tester will find the maximum voltage value and the reconnect phase.
GDCR602 test set include four high frequency response dividers which are installed to the three phase lines and
neutral points to measure the voltage capacitor groups. GDCR602 is based on new DSP and embedded
computer technology. 12.1 TFT LCD is designed for data display. All the sample channels are isolated to each
other. The main box of GDCR602 could be used as a signal recorder. It has a extensive processing software.
The data process software include automatic power generator test template, signal recorder test template,
power quality analysis, spectrum analysis tools, flexible figure tools and so on.
