This standard presents engineering design procedures for the electrical protection of communication facilities serving electric supply locations through the use of isolation transformers. Othere telecommunication alternatives such as radio and microwave systems are excluded from this document. This standard presents workable methods that can be used with greater reliability to improve the electrical protection of communication facilities serving electric supply locations through the use of isolation transformers. New IEEE Standard - Inactive-Reserved. Engineering design procedures for the electrical protection of communication facilities serving electric supply locations through the use of isolation transformers are presented in this standard. These isolation transformers are hard-wired (i.e., have no plug-in units and are not modular).
