Mvax 11: Tripping and Interposing Supervision Relay by rithushiva is a document available to read on EtoBox.
MVAX 11 relay supervises the trip circuit of tripping relays such as the MVAJ or interposing control relay Type MVAW. It has two dropping resistors R1 and R2 of equal ohmic value, connected in series with the coil. Under healthy conditions the relay coil is energised via the dropping resistor R2 as shown in Figure 1 and in Figure 2. If the circuit being supervised becomes open circuited or if the supply fails, the relay
