Included are sections on transmitting and receiving equipment, leased voice grade channels, application principles, installation, and testing. The primary purpose of this document is to guide the power system user in applying, installing, and operating audio-tone protective relaying systems over voice grade channels. Secondly, it is to provide a reference for equipment manufacturers engaged in the design and application of relaying equipment and for telephone personnel engaged in providing telecommunications channels for audio-tone protective relay schemes.IEEE Std C37.93-2004 (Revision of IEEE Std C37.93-1987): IEEE Guide for Power System Protective Relay Applications of Audio Tones Over Voice Grade ChannelsIEEE Std C37.93-2004 Protective relaysStandardsTelephone communication channelsStandardsProtective relaysStandards.Telephone communication channelsStandards.621.317IEEE-SA Standards Board,NjHacINjHaclDOCUMENT996280649903316IEEE guide for power system protective relay applications of audio tones over voice grade channels3574549UNISA
