Application of electronic load circuit for electrical safety by using a serial mode comparator

This research presented an electronic load circuit for electrical safety by using a serial mode comparator as a protection device against surges caused by electrical power lacking stability and quality. The application of comparators in detecting overvoltage and driving electronic load is possible because of a transistor which is a simple device for failure prevention used in the circuit design. The properties of the circuit can be set. Relation management for failures which might occur in the electrical system is done through SPDs for surge protection. The electronic load is used as a device to reduce swell. The experiment showed that the electronic load circuit could work according to the design, without any failure, and was efficient. The let-through voltage which came to the load did not reach the level at which electrical devices and electronics would get the failure. The circuit could work without interruption. Moreover, the results from the Failure Modes and Effects Analysis (FMEA) showed that they met the specified standards.
