Various manufacturers of relay protection devices only offer two options of setpoints, which should be changed manually by the operating staff at the place of protection installation. This means that these devices do not have the ability to adapt the protection response current to changing environmental parameters, which have a significant impact on overhead power lines parameters. As a result, the setpoint set on a microprocessor relay device is not always correct and can lead to failure of the relay protection or to a false positive.
