UR-8HH CT/VT(UR-8HH GE) FAQ


Q1: What is the primary function of the UR-8HH GE module within the GE Universal Relay system?

A1: The UR-8HH GE isolates, scales, and samples high-voltage and high-current grid signals, transforming them into digital data for protection and metering.
Q2: What specific sensor inputs can be directly wired to the UR-8HH GE terminal blocks?
A2: The UR-8HH GE connects to 3 phase current transformers (1A/5A), 1 ground current transformer (1A/5A), and 4 voltage transformers.
Q3: How does the sampling rate of the UR-8HH GE impact the power system's protection speed?
A3: Operating at 64 samples per cycle, the UR-8HH GE captures transient faults and harmonics quickly to ensure fast, precise protection tripping.
Q4: Since GE has declared the 8H hardware platform End-of-Life, can I still use my existing UR-8HH GE?
A4: Yes, you can use your current UR-8HH GE(UR-8HH input module) modules, but routine offline calibration checks are recommended since it lacks advanced internal self-test diagnostics.
Q5: What should I do if my UR-8HH GE module fails, considering its discontinued status?

A5: If your UR-8HH GE(UR-8HH input module) fails, you can contact our Spare Center directly to purchase a reliable, tested replacement, or consult us for upgrading to a newer generation module.
