One Analog and 5 KYZ Circuits

System 1 is designed to telemeter power measurements: volts, amps, kWh, kVARs. The system provides 1 analog point and 5 KYZ relay links using mercury-wetted relay contacts. Larger systems can be provided as specified. Readings are taken by using dedicated telephone lines between stations or a station dial-up on the public dial network. A standard telephone at the local receiving site dials the remote and initiates the readings. The dial-up interface will be available in 2000.
