Electrical Power Monitoring System Using Thermochron Sensor and 1-Wire Communication Protocol

Maintaining quality and reliability of operation of remotely located electrical machines as well as power supply equipment by monitoring their load is an important task in modern practical electrical engineering. This paper presents a low-cost efficient, robust and relatively simple load monitoring electronic system based on the use of special encapsulated temperature sensors-data loggers (so-called Thermochron iButtons) combined with application of 1-wire data communications implemented on the power supply line, dedicated data communication line with off-line data transfer.
