Numerical Voltage, Frequency and Overexcitation Protection Relay
The SIPROTEC 7RW600 is a numerical multifunction protection relay for connection to voltage transformers. It can be used in distribution systems, on transformers and for electrical machines. If the SIPROTEC 7RW600 detects any deviation from the permitted voltage, frequency or overexcitation values, it will respond according to the values set. The 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.
The SIPROTEC 7RW600 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.
This device is intended as a supplement to Siemens substation systems and for use in individual applications. It has two voltage inputs (V; Vx) to which a variety of functions have been assigned. While input V serves all of the implemented functions, input Vx is exclusively dedicated to the voltage protection functions. The scope of functions can be selected from three ordering options.
– 24, 48 V DC
– 60, 110, 125 V DC
– 220, 250 V DC, 115 V AC
