Product Description
The 6 Phase Relay Protection Tester is a professional secondary injection test set designed for testing modern numerical protection relays, conventional electromechanical relays and complex protection systems.
With independent current and voltage output channels, the tester can simulate different power-system operating and fault conditions with precise control of current amplitude, voltage amplitude, phase angle, frequency and harmonic components.
Six-phase relay test sets are particularly useful for advanced applications such as transformer differential protection, busbar protection and multi-terminal protection testing. Commercial six-phase systems commonly provide independent simultaneous current and voltage outputs for these applications.

Customer Pain Points
“Our protection scheme is becoming more complicated."
A six-phase test set provides more independent channels than a basic three-phase tester, making it easier to reproduce complex protection conditions.
“We need to test transformer differential protection."
Independent multi-phase outputs allow engineers to simulate different current relationships required for differential protection tests.
“We need accurate phase-angle control."
Protection testing requires precise control of amplitude, phase and frequency. Modern relay test sets provide independent control of these parameters.
FAQ
Q: Why choose a 6-phase relay tester instead of a 3-phase tester?
A six-phase tester provides more independent output channels, which is useful for differential, busbar and other complex protection applications.
Q: Can it test numerical relays?
Yes. Six-phase relay test sets are widely designed for modern microprocessor-based/numerical protection relays.
Q: Can it test transformer differential protection?
Yes. This is one of the important applications of multi-phase relay test equipment.
