FAQ
Q: What types of phase current transformers does the UR8CH support?
A: It supports standard 1A or 5A secondary current inputs for compatibility with industrial CTs.
Q: What support does the UR8CH provide for ground fault detection?
A: It includes a dedicated ground current CT channel (1/5A) for sensitive zero-sequence current detection.
Q: Can the UR8CH operate in extreme outdoor substation temperatures?
A: Yes. It works reliably from -25℃ to +70℃ in harsh seasonal environments.
Q: How is the UR8CH mounted in the relay rack?
A: It is screw-mounted on the back of the rack for strong mechanical stability under vibration.
Q: Is the UR8CH resistant to high-humidity conditions?
A: Yes. It operates in 5%–95% non-condensing humidity with industrial-grade moisture protection.
