Predictive units like marine instrumentation and protective devices for heavy-duty machines and automation process control are very essential. The main aim of such units and devices is to keep systems to continue running without fail, without any damage. Let us discuss some of them. HRG System It is a high resistance grounding system that is installed to reduce mechanical stresses in circuits and prevent any equipment destruction. This device is helpful in ensuring the safety of people and properties close to the ground fault. Potentiometer The motorized potentiometer is installed in and for industrial automation and process control applications. Its function is to give speed reference to any electronic regulator or controller (AVR controllers). Arc Flash Relay It is also called arc protection relay. The main function of this device is to provide unmatched switchgear protection by reducing arc flash energy. Gen Controller The main purpose of the flexgen generator controller is to e...
