ZX-802 Microcomputer Relay Protection Tester
The ZX-802 Microcomputer Relay Protection Tester adopts high performance IPC as the host computer, Window XP system, device panel with large size color TFT display device, the front panel provided with a plurality of USB which is convenient for data access, data communication and software upgrade.
Manual
Video1.through setting corresponding voltage or current as variables.
2giving the variable certain changeable step size and selecting suitable testing mode (‘manual operation’, ‘semi-automation’ and ‘full-automation’ three modes are available) to test action value return value.
3.action time and return time of all kinds of voltage and current protection conveniently, and calculating return factor automatically.
4.Since the ‘four-phase voltage and three-phase current’ unit is used frequently and the operating method of other units is basically the same as it.
5. we only take the ‘four-phase voltage and three-phase current’ as the example to introduce in detail.
