Introduction: Prok dv’s make Microcontroller Based Motor Protection Relay PD-MMPR-303 uses the State-Of-The-Art Microcontroller based measurement techniques for providing protection for Motors up-to 75HP. The comprehensive protection features of the relay makes it ideal for Motor protection. The heart of the relay is microcontroller based reliable hardware with special algorithms to calculate the tripping time. The relay continuously monitors the Three Phase Currents to build the thermal replica of the Motor. This thermal replica is used to protect the Motor against Thermal Over Loads. The Microcontroller Based Motor Protection Relay does not require external Current Transformer (CT) for its operation. The three phase R, Y and B cables are made to pass through the CT hole which is in the relay. The built in CT’s takes care of stepping down of the Currents to the required level. The stepped down three phase Currents are continuously monitored by the more...
