FAQ
FAQ
Q1: What is the GE Multilin UR8LH used for?
The UR8LH is a CT/VT input module that supplies current and voltage measurement signals to GE Multilin UR Series protection relays for protection, control, and metering applications.
Q2: Which relays are compatible with the UR8LH?
The UR8LH is designed for the GE Multilin Universal Relay (UR) Series, including models such as T60, F60, L90, D60, G60, C60, and B90, depending on relay configuration.
Q3: What CT ratings does the UR8LH support?
The module supports 1 A and 5 A CT secondary inputs, depending on the relay configuration and wiring arrangement.
Q4: What VT input range is supported?
The UR8LH accepts 50–240 VAC nominal VT secondary inputs, with a measurement range extending from 1 V to 275 V.
Q5: What is the operating frequency range?
The module operates with power system frequencies from 20 Hz to 65 Hz, supporting both 50 Hz and 60 Hz applications.
Q6: Can the UR8LH be replaced without changing relay settings?
In most cases, the module can be replaced directly with the same model and hardware revision. However, configuration and calibration should always be verified after installation using EnerVista UR Setup.
Q7: What applications commonly use the UR8LH?
The UR8LH is widely used in transmission line protection, transformer protection, feeder protection, generator protection, bus protection, and industrial power management systems.
Q8: What should be checked before replacing a UR8LH module?
Before replacement, verify the relay model compatibility, CT/VT wiring, secondary ratings (1 A or 5 A), hardware revision, module slot position, and relay configuration. After installation, confirm analog measurements and protection settings using EnerVista software.
