36. Operation Referring to the accessory schematic diagram Figure 21 the phase currents are rectified by the diode bridges D103 through D116 Current out of the positive side of the bridge passes through diode D127 and divides into two parallel circuits One circuit consists of zener D123 and the minimum phase actuating resistor R301 to the other side of the bridge The other circuit consists of nor mally closed contact 1516 of latching relay RY1 diode D201 and capacitor C201 to the other side of the bridge C201 charged by load or fault current provides tripping energy for RY1 The current through R301 produces a voltage drop pro portional to the line current which is impressed across the series resistor string R101 R102 and R103 A por tion of this voltage is applied through diode D120 to the base of transistor Q201 When this voltage exceeds the break down voltage of zener D212 and the base emitter junctions of Q201 and Q202 Q201 will conduct causing Q204 to conduct In turn Q204 provides the gating current to turn on the SCR Q206 to discharge capacitor C201 through the trip coil of the latching relay RY1 Contacts 10 11 and 7 8 of RY1 in series with the close coils of the high voltage switch es open to prevent the high voltage switches from clos ing until the fault block circuitry is reset An important feature of this accessory is that a trip signal cannot be initiated until there is sufficient charge on C201 to activa
