INTEGRATED PROTECTION & CONTROL SOLUTION FOR MOTOR MANAGEMENT BLOCK MICOMP225

Application:-
1. Comprehensive MV motors protection with power and energy measurement

Protections:-
1. Thermal overload with thermal image. Configuration of 3 thermal time constants (starting, overload, cooling), 3 stages of thermal loading: alarm, trip and inhibition of CB closing
2. Three-phase over current against phase-to-phase faults, 1-stage
3. Earth fault, 2-stage
4. Excessive starting time. Overcurrent criteria
5. Locked rotor while running or starting. Overcurrent criteria
6. Unbalance, loss of phase and single phasing.
7. 2-stage protection based on negative sequence component of the current
8. Loss of load. 1-stage. Undercurrent criteria
9. Temperature supervision. Co-operation with 10 RTD sensors (Pt, Ni, Cu) or 3 thermistors.
10. 2-stage setting for each channel.
11. Limitation of the number of successive start-ups. Separate settings for cold
12. hot start-ups. Inhibition of CB closing after last unsuccessful start-up. Separate settings for cold and hot start-ups
13. Undervoltage
14. Anti-backspin protection

Measurements
1. Phase currents (up to 10th harmonic)
2. Earth current
3. Voltages
4. Power P, Q, S
5. Energy: active, reactive
6. Thermal load
7. Temperature
