Two points are tested, per phase, test element. In order to test the directional units, configure (in the Setpoint > Relay Configuration > Protection Elements screen of the EnerVista 650 Setup program), some overcurrent element to be su pervised by a directional unit. This way, if the directional element is enabled and detects the fault in the block direction, then the overcurrent unit does not operate. If the directional element is not enabled or if it is enabled and it detects a fault in a trip direction, then the overcurrent unit operates if the set current level is exceeded. 6.13.1 67P element Activate only protection elements 50PH and 67P and set the relay as follows: Configure one of the outputs to be activated only by unit 50PH.
