GE UR8FH CT/VT module
GE UR8FH CT/VT module
DESCRIPTION
General Electric Multilin’s UR-8FH is a CT/VT module designed for installation in the Universal Relays series. It provides the relay with 3-1A/5A phase current transformers, 1A/5A ground current transformers, and four voltage transformer terminals. Current transformers and voltage transformers are capable of scaling down current and voltages to manageable levels for relay monitoring and control, and are necessary for producing vital data for the relay.
Functional Characteristics
Current and Voltage Measurement:
This module provides 3 1A/5A phase current transformers, 1A/5A ground current transformer and four voltage transformer terminals for the relay.
The current transformers and voltage transformers are capable of reducing current and voltage to manageable levels for relay monitoring and control, and are necessary to generate critical data for the relay.
Data Isolation and Protection:
In addition to providing data from the power system, current transformers are able to isolate the system from extreme currents and voltages, thereby extending system life and reducing general maintenance costs.
Voltage transformers increase user safety and reliably measure power system voltage.
Highly configurable CT/VT settings:
CT/VT settings can be highly modified to create unique protection schemes such as differential protection, concurrent phase splitting protection, etc., thus increasing the versatility of the module.
Possible Enhanced Diagnostics:
Similar to GE's other CT/VT modules, the UR8FH may also have enhanced diagnostic features that can verify the integrity of the analogue signals and ensure that components are functioning properly. However, it is important to refer to the product manual or consult with the manufacturer to determine if this feature is available.
Applications and Compatibility
Applications:
The UR8FH CT/VT module is suitable for a variety of power system applications such as power plants, substations, etc. where accurate current and voltage measurements are required.
Compatibility:
The module is compatible with the Universal Relay family and can be managed and programmed with the appropriate software package.
Firmware versions may affect the compatibility of CT/VT modules and CPUs within a particular relay. Therefore, when installing or upgrading, please ensure that the firmware version is compatible with the hardware.
Installation and Maintenance
Installation Guide:
Before proceeding with the installation, please read the product manual and installation guide carefully to ensure proper installation and connection.
Take care to match the rated current and secondary ratings of the voltage transformer to avoid system damage.
Maintenance Recommendations:
Regular inspection and maintenance of the CT/VT module will ensure proper operation and prolong its service life.
If any abnormality or malfunction is detected, stop using it immediately and contact the manufacturer or professional maintenance personnel for overhaul.
Precautions
Safety Precautions:
During operation and maintenance, please follow the relevant safety regulations and operating procedures to ensure personal and equipment safety.
Environmental requirements:
Please ensure that the module is installed in a place that meets its working environment requirements to avoid overheating, humidity and other unfavourable conditions affecting the module performance.
