UR8HH CT/VT电流互感器特点和注意事项

特点：

Features:

Sensitive grounding protection: UR8HH provides a grounding protection sensitivity ten times higher than the basic model, which is crucial for detecting grounding faults in power systems.

Highly configurable: Users can configure it through the keyboard and LCD interface of a universal relay, or through the EnerVista software program of Multilin, making settings and adjustments very flexible.

Communication capability: The module can communicate with general relays through RS232 port or Ethernet connection, facilitating remote monitoring and configuration.

CT/VT scheme customization: Users can set different CT/VT schemes for highly specified protection based on specific system requirements, such as phase separation and differential protection.

Vertical installation version: UR8HH has a vertical installation version specifically designed for the universal relay series, suitable for power system environments with limited space.

Notes:

Installation type: Confirm whether the purchased module is a horizontal or vertical installation version, as there are significant physical differences between the two.

System compatibility: Ensure that the UR8HH module is compatible with existing power systems and relays to avoid issues caused by incompatibility.

Configuration and programming: Use EnerVista software or other configuration tools correctly to ensure that all settings meet the specific requirements of the power system.

Maintenance and Inspection: Regular maintenance and inspection of modules, including cleaning, checking connections, and updating firmware, to maintain optimal performance.

Redundant power supply: If the module supports the redundant power supply option, ensure proper configuration so that the backup power supply can take over immediately in the event of a main power supply failure.

LED indication: Pay attention to the LED indicator lights on the module panel, which can indicate the status of the module and any potential faults.

Technical documentation: Before operating and configuring the UR8HH module, it is essential to read and understand the technical documentation and user manual provided by the manufacturer.

Professional training: Operators should receive professional training, be familiar with the functions and operating procedures of the module, and avoid incorrect operations.
