Short Circuit / Relay Coordination Study Services by Q Sine
Relay Coordination study: Once the relay parameters have been set, a coordination study is performed to ensure that the selected protective relays operate in the desired sequence. The coordination study involves simulating various fault scenarios and verifying that the protective relays operate in the intended sequence.
- Detailed report explaining the input data, system configuration, observations and recommendations
- Fault currents at various buses and branches in the system
- Relay setting charts/tables with optimum settings
- Time coordination curves
- Sequence of Operation
- Relay setting soft file
- Input to Arc Flash Study
