【功能描述】
产品描述
General Electric Multilin 的 UR-8FH 是一款 CT/VT 模块，设计用于安装在通用继电器系列中。它为继电器提供 3-1A/5A 相电流互感器、1A/5A 接地电流互感器和四个电压互感器端子。电流互感器和电压互感器能够将电流和电压降低到可管理的水平，以便进行继电器监测和控制，并且是为继电器生成重要数据所必需的。
CT/VT 模块可以在通道 1 到 4（含）或通道 5 到 8（含）上使用电压或触点输入。UR手册提供了有关正确继电器连接的更多信息，指出了重要的细节，例如通道1和5如何连接到A相，通道2和6如何连接到B相等。这些手册还向用户提供了完整的警告和通知，例如，与继电器端子的标称电流为 1 A 或 5 A 的连接必须与所连接 CT 的次级额定值相匹配，以免用户希望造成系统损坏。总之，用户在开始进行继电器连接过程之前仔细阅读通用继电器手册非常重要。被描述为具有标准4CT/4VT功能。它没有敏感的接地功能，这使得通用继电器可以在被归类为高阻抗的接地系统上受到保护。具有此功能的模块还包括UR-8G、UR-8J、UR-8M和UR-8R订购代码。

【英文介绍】
Product description
General Electric Multilin's UR-8FH is a CT/VT module designed to be installed in the general purpose relay family. It provides the relay with 3-1A/5A phase current transformer, 1A/5A ground current transformer and four voltage transformer terminals. Current transformers and voltage transformers are able to reduce current and voltage to manageable levels for relay monitoring and control, and are necessary to generate important data for relays.
CT/VT modules can use voltage or contact inputs on channels 1 to 4 inclusive or channels 5 to 8 inclusive. The UR manual provides more information on proper relay connections, pointing out important details such as how channels 1 and 5 are connected to phase A, and channels 2 and 6 are connected equally to B. These manuals also provide the user with complete warnings and notifications, for example, that connections with A nominal current of 1 A or 5 A to the relay terminal must match the secondary rating of the connected CT, lest the user wish to cause system damage. In summary, it is important for users to read the general relay manual carefully before starting the relay connection process. Described as having standard 4CT/4VT functionality. It has no sensitive grounding function, which allows general purpose relays to be protected on ground systems classified as high impedance. Modules with this feature also include UR-8G, UR-8J, UR-8M, and UR-8R ordering codes.
