Wood Group ESP, part of international energy services company John Wood Group PLC, has introduced the iMonitor Motor Protection System designed for use with downhole electric submersible pump (ESP) motors and medium to large sized induction motors on surface pumps. Part of Wood Group ESP’s family of control and communication products, the iMonitor system, can be used as a stand-alone motor controller or interfaced directly to an automated control system. iMonitor is a fixed-speed motor controller and data acquisition device. The control unit continuously monitors input power and motor load conditions. When coupled with the optional iMonitor Data Logger, the system gathers operating information including system run time, system shutdowns, automatic or manual restarts and motor current draw. Additionally, to help guard against loss of pump flow, loss of pressure and other conditions that can potentially damage a pump; the system can monitor external sensors and protective devices.
