WebIRV Phase Relay The design of the instantaneous overcurrent unit of the IRV phase relay is similar to the ground relays except it receives its energy from the phase current transformers. Also, as shown in figure 8, the capacitor phase shifting circuit is controlled by the normally open contact of the directional unit. WebThese relays are mounted in a size S2 drawout case. The outline and panel drilling is shown in figure 16. The basic differences between the various model relays are listed in Table 1. The RPM11D and RPM11H relays are suggested for standard applications. TABLE 1 RELAY INTERNAL TIMING TYPE CONN RANGE figure Seconds
