Digital voltage / frequency / over-excitation protection relay Siemens Power Transmission Distribution

SIPROTEC 7RW600 is a numerical, multifunction relay for connection to voltage transformers. It can be used in distribution systems, on transformers and for electrical machines. If it detects any deviation from the permitted voltage, frequency or overexcitation values, it responds according to the values set.

SIPROTEC 7RW600 can be used for the purposes of system decoupling and for load shedding if ever there is a risk of a system collapse as a result of inadmissibly large frequency drops. Voltage and frequency thresholds can also be monitored.

This voltage, frequency and overexcitation relay can be used to protect generators and transformers in the event of defective voltage control, of defective frequency control, or of full load rejection, or furthermore islanding generation systems.
