FAQ
Q: Why do we need 6-phase current output?
A: Many complex protection devices require multiple current inputs:
- Busbar differential protection needs 6~12 branch current inputs
- Three-winding transformer differential protection needs high/medium/low voltage side 6 current inputs
- Double busbar protection needs multiple branch and tie breaker current inputs RPT-4632's 6-phase current output can complete these tests in one connection, eliminating the need for repeated wiring and improving test efficiency by 300%.
Q: What is the function of GPS synchronization?
A: For line longitudinal differential protection, the protection devices on both sides of the transmission line need to operate synchronously. The built-in GPS module of RPT-4632 can synchronize two testers located at both ends of the line with <1ms accuracy, truly simulating internal and external faults of the line and verifying the correct operation of the longitudinal differential protection.
Q: Can it output 180A continuous current?
A: Yes. By connecting the six current phases in parallel, RPT-4632 can output up to 180A continuous current, which meets the test requirements of high-current busbar differential protection and generator differential protection. The output time can be set arbitrarily from 0.1s to 9999s.
Q: Is it suitable for conventional protection testing?
A: Yes. In addition to complex multi-branch protection tests, RPT-4632 also supports all conventional protection test modules, including line protection, two-winding transformer protection, generator protection and automatic device testing. It can be used for both conventional and complex protection tests.
