The function of a Motor Protection Relay (MPR) is to protect three-phase induction motors and additionally to communicate this data to the System Control and Data Acquisition (SCADA) in a control room. In the case of remote sites e.g. a pump station, the protection relays are used as standalone units. If a trip occurs or settings need to be changed a technician has to visit the remote site and address the problem. The ideal cost and time effective solution is to remotely perform these tasks via a reliable wireless network. A study was conducted to ascertain the viability of using the standard GSM cellular networks in South Africa to effectively control electric motors and to communicate with MPR's. It was shown that a Node Controller could be used to store all the data from various electric motors at a single location.
