FAQs
What is a 6-phase protection relay testing kit?
A: It is a secondary injection test set with six current and six voltage output channels. It is used to calibrate and verify electromechanical, static, and numerical relays in substations and power grids.
Why use 6 phases instead of 3?
A: Six phases are required for testing differential protection relays, especially for simulating currents from both sides of a transformer or busbar. This ensures proper operation. It also supports more complex tests like those for ATS (Automatic Transfer Switch) and fast-cutting devices.
What are the key features to look for?
A:
-
High Precision: Accuracy typically around 0.05% to 0.2% for both voltage and current.
-
Automation: GPS synchronization and PC software for automated testing and reporting.
-
Versatility: Independent DC power supply (usually 110V/220V) for powering relays.
-
Portability: Integrated design with built-in keyboards and LCD screens for easy field use.
How often should relays be tested with these kits?
A:
-
ANSI/NFPA 70B recommends testing every two years.
-
IEC standards suggest testing every three years.
What are the common testing procedures?
A:
-
Visual Inspection: Check for physical damage or corrosion.
-
Insulation Resistance: Ensure electrical safety.
-
Functional Testing: Verify pick-up, drop-out values, and timing accuracy.
-
Fault Simulation: Replay COMTRADE files or simulate transient faults to verify relay response.
What tests can be done with a 6-phase relay tester?
A: A 6-phase relay tester is used for complex diagnostics and verification of power system protection. It outputs six current and six voltage channels, ideal for tests like transformer differential protection.
