Description
The CT/VT8H UR8HH is a high-precision CT/VT module designed specifically for relay protection and power monitoring systems. As the sensing core of substation automation and feeder protection systems, this module can capture analog signals from current transformers (CTs) and voltage transformers (VTs) in real time and convert them into high-speed digital streams that the system can recognize.
Applications
Intelligent Substation Plants: Collect busbar and feeder data for protection systems.
Heavy Industrial Power Plants: Monitor high-voltage motor status to prevent electrical faults.
Wind Power Plants: Monitor turbine output quality and support grid protection control.
Petrochemical Power Plants: Provide continuous monitoring for early fault detection and isolation.
Features
High Reliability: Employs industrial-grade components and design, ensuring reliable operation in harsh environments.
Sensitive Grounding Function: Allows the relay to proportionally reduce its current and voltage ratings.
Comprehensive Protection Function: In addition to basic protection functions, it provides protection against special fault types, such as resonant overvoltage and transient overcurrent.
Software Integration
EnerVista UR Software: Enables efficient configuration and data visualization
EnerVista Viewpoint UR Engineer: Drag-and-drop environment for rapid commissioning
Interface: Provides a user-friendly and well-organized display for settings and data review
