GE UR8GH  CT/VT模块 高灵敏度的接地保护 

【产品详情】

UR-8GH是为GE Multilin的通用继电器系列设计的众多模块之一，是一种CT / VT模块，通过其电流变换和电压变换功能提供敏感的接地保护。该模块比该模块的基本型号有了显着的改进，因为其敏感的接地保护功能使其对该品种的故障检测敏感十倍。

UR-8GH模块可通过通用继电器的键盘和LCD编辑系统设置进行高度配置，或者通过Multilin的EnerVista软件程序更轻松地进行配置。EnerVista 程序可以通过位于设备面板上的 RS232 端口直接连接到继电器，或者通过以太网连接（如果给定设备上可用）。继电器的设定点允许用户设置不同的CT/VT方案以实现高度指定的保护，例如为系统建立并发分相和差动保护。

通用电气Multilin的UR-8GH还提高了用户的安全性，因为它在通用继电器从外壳中取出时具有自动短路机制。此外，通过降低额定电压和电流实现的监控功能可以更好地了解系统及其需求，为用户提供有价值的信息，以改进其系统并解决危险故障及其原因。最后，继电器的高级健康诊断可以验证 CT/VT 信号的完整性，确保所有数据准确且正确生成。

关于 UR-8GH 的常见问题

UR 系列多林万向继电器中包含的 UR-8GH 有哪些特点？

部件 UR-8GH 是一个 CT/VT 模块，由“UR”名称后面的部件号中包含的“8”指定。优傲继电器系列的所有 CT/VT 模块都有此编号。UR-8GH是较新的CT / VT模块之一。UR-8GH Multilin CT/VT 模块具有灵敏接地 4CT/4CT 配置。新CT/VT模块的其他订购选项包括8F选项（标准4CT / 4VT），8H选项（标准8CT），8J选项（敏感接地8CT），8L选项（具有增强诊断功能的标准4CT / 4VT），8M（具有增强诊断功能的标准接地4CT / 4VT），8N（具有增强诊断功能的标准8CT）和8R（具有增强诊断功能的标准8CT）。Multilin UR CT/VT 模块可配置多达 24 个电压互感器和电流互感器信号，以监控电源线。该模块支持 5 A 和 1 A 电流互感器。上面列出的某些CT/VT模块的敏感接地选项意味着，即使接地系统被归类为高阻抗情况，它们也能够为设备提供接地故障保护。

【英文介绍】

UR-8GH, one of many modules designed for GE Multilin's family of universal relays, is a CT/VT module that provides sensitive ground protection through its current and voltage conversion functions. This module is a significant improvement over the basic model of this module, as its sensitive ground protection feature makes it ten times more sensitive to fault detection of this variety.

The UR-8GH module can be highly configured with the keyboard and LCD editing system Settings of the universal relay, or more easily configured with Multilin's EnerVista software program. The EnerVista program can be connected directly to the relay via an RS232 port located on the device panel, or via Ethernet if available on the given device. The set point of the relay allows the user to set different CT/VT schemes to achieve highly specified protection, such as establishing concurrent phase separation and differential protection for the system.

Ge Multilin's UR-8GH also improves user safety because it has an automatic short-circuit mechanism when the general purpose relay is removed from the housing. In addition, the monitoring capabilities achieved by lowering the rated voltage and current provide a better understanding of the system and its requirements, providing users with valuable information to improve their system and address dangerous failures and their causes. Finally, the relay's advanced health diagnostics verify the integrity of the CT/VT signal, ensuring that all data is accurate and generated correctly.

Frequently Asked Questions about UR-8GH

What are the features of UR-8GH included in UR Series Dolin universal relays?

Part UR-8GH is a CT/VT module, designated by the "8" contained in the part number following the "UR" name. All CT/VT modules in the Yoo relay series have this number. UR-8GH is one of the newer CT/VT modules. The UR-8GH Multilin CT/VT module has a sensitive grounded 4CT/4CT configuration. Additional ordering options for the new CT/VT modules include the 8F option (Standard 4CT / 4VT), 8H option (Standard 8CT), 8J option (Sensitive Ground 8CT), 8L option (Standard 4CT / 4VT with enhanced diagnostics), 8M (Standard Ground 4CT / 4VT with enhanced diagnostics), 8F option. 8N (Standard 8CT with enhanced diagnostic function) and 8R (standard 8CT with enhanced diagnostic function). The Multilin UR CT/VT module can be configured with up to 24 voltage transformer and current transformer signals to monitor the power line. The module supports 5 A and 1 A current transformers. The sensitive grounding options of some CT/VT modules listed above mean that they are able to provide equipment with ground fault protection even if the grounding system is classified as a high impedance case.
