GPS Control Test
Process of full group test can be controlled by GPS for simulating the simultaneous and synchronous test of the protection on two sides of double power supply circuit, which means these two testers on two sides will be started simultaneously and synchronously by GPS controller to enter the state before fault and the state of fault. Loading the protection for each side given by component of fault for testing the simultaneous action of two sides' protection.
- GPS Pulse Output：
The pulse export of GPS tester will output two lines of pulse, one is PPS pulse that will be transmitted every second; another is PPM pulse that will be transmitted every minute. Every time when PPS or PPM pulse is transmitted, a PPS indicating lamp and a PPM indicating lamp on faceplate will twinkle. We hereby do test by using PPM pulse. Output of pulse is terminal output.
- Outputting GPS Clock Signals
There is RS232 out let in GPS tester for outputting clock. Out let is Type D 9 needle socket. Connecting this out let with RS232 port of PC, and PC machine will read GPS time.
- Connection between GPS Tester and Tester Tester：
By using the special GPS connecting wire provided by us, connecting the pulse output terminal and clock output Rs232 port of GPS tester with the GPS communication port on backplate of tester.
Comparing the time with GPS tester：
For ensuring test's synchronization, click 'read GPS clock' on the 'Full Group Test' interface of PC machine to implementing the synchronous clock with GPS tester. If comparing the time with it is successful, a hint will be displayed.
