TEPI1接口是公用事业级通用多路复用器FOX615的一部分，它为电力公用事业应用提供了特定的解决方案。TEPI1专为距离保护应用而设计。因此，它提供了应用所需的功能，并满足相关的远程保护产品标准，如IEC 60834-1和IEEE 1613以及EMC标准EN 61000-6-3和EN 61000-6-2。高度集成的FOX615解决方案与远距离保护应用的TEPI1为电力公司提供了许多好处，例如在出现问题时快速报警，使用网络管理系统进行全面远程配置和控制的可能性，以及由于较少的单个盒子和冗余通道路由而具有更高的可用性。
与FOX515的互操作性
四个TEPI1远程保护命令与FOX515 TEBIT可互操作。这意味着只需添加一个带有TEPI1的FOX615，就可以很容易地扩展FOX515网络。您的远程保护应用程序的性能得到充分保证。
TEPI1架构
TEPI1是可插入FOX615机箱的大量接口模块的一部分。像所有FOX615模块一样，TEPI1是:
-由FOX615架子供电
-由FOXCST配置
-由FOXMAN-Management系统监督
两个前端连接器提供对远程保护和通用(二进制)输入和输出的访问。同样是电隔离，并提供的电磁兼容抗扰度恶劣环境。TEPI1包括一个非易失性事件记录仪，具有出色的精度，可以通过GPS(定位系统)同步。

The TEPI1 interface is part of the utility grade universal multiplexer FOX615 which provides specific solutions for power utility applications. TEPI1 has been specifically designed for distance protection applications. Therefore it provides exactly the features required by the application and fulfils the relevant teleprotection product standards such as IEC 60834-1 and IEEE 1613 as well as EMC standards EN 61000-6-3 and EN 61000-6-2. The highly integrated FOX615 solution with TEPI1 for distance protection application provides many benefits for power utilities such as fast alarming in case of problems, full remote configuration and control possibilities using the network management system and higher availability due to less individual boxes and redundant channel routing.
Interoperability with FOX515
The four TEPI1 teleprotection commands are fully interoperable with FOX515 TEBIT. This means that an extension of a FOX515 network is easy possible by just adding a FOX615 with TEPI1. The performance of your teleprotection application is fully guaranteed.
TEPI1 architecture
The TEPI1 is part of a large complement of interface modules which can be plugged into a FOX615 shelf. Like all FOX615 modules TEPI1 is:
– powered from the FOX615 shelf
– configured by FOXCST
– supervised by FOXMAN-Management system
Two front connectors provide access to the teleprotection and general purpose (binary) inputs and outputs. The same are galvanically isolated and provide highest EMC immunity for harsh environment. TEPI1 includes a non-volatile event recorder with an outstanding accuracy, which can be synchronized by GPS (Global Positioning System).
