In synchronization processes, the relay ensures that phase, voltage, and frequency differences between systems are within acceptable limits before interconnection. - Reclosing Sequences:
Often used in automatic reclosing operations, the relay prevents unnecessary tripping by allowing time for transient faults to clear. - Generator Protection:
The relay plays a pivotal role in the manual synchronizing of generators by safeguarding against phase mismatches, and ensuring seamless integration into the grid. - Circuit Breaker Operations:
Acting as a check synchronizing relay, it ensures that circuit breakers close only when the conditions meet pre-defined parameters, thereby preventing damage. - Transformer and Motor Protection:
By introducing precise time delays, the relay provides enhanced coordination between primary and backup protection devices.
Enhancing Precision: Key Functionalities
The ALSTOM VTT11ZG8143BCH offers advanced functionalities that contribute to its precision:
- Phase Difference Measurement: The relay measures the phase difference between two supply voltages using an innovative algebraic subtraction technique. The resulting waveform is compared against a DC reference, ensuring accurate detection of phase variations regardless of supply voltage fluctuations.
- Frequency Difference Measurement: Frequency differences are monitored by assessing the phase angle traversed over a defined period. The calibrated timer operates the relay if the phase difference persists, ensuring stable and consistent frequency measurement.
- Voltage Difference Measurement: Voltage lockout features inhibit the relay’s operation when voltage conditions are outside acceptable limits. Two options are available:
- Amplitude Comparison: The relay compares individual voltage amplitudes against a stabilized DC reference.
- Voltage Difference Lockout: It inhibits operation if the voltage difference exceeds pre-set limits, adding an additional layer of protection.
