7rw80 High Efficiency Electrical Voltage Frequency Protection Relay

We Export, Distribute, Trade, and supply 7RW80 Voltage Frequency Protection Relays in Navi Mumbai, Maharashtra, India. The SIPROTEC Compact 7RW80 is a numerical, multi-function relay for connection to voltage transformers. It can be used in distribution systems, on transformers, and for electrical machines. If the SIPROTEC Compact 7RW80 detects any deviation from the permitted voltage, frequency, or over-excitation values, it will respond according to the values set. The relay can also be applied for system decoupling and load shedding if ever there is a risk of a system collapse due to inadmissibly large frequency drops.

An integrated load restoration function allows the re-establishment of the power system after recovery of the system frequency. The 7RW80 features flexible protection functions. 20 additional protection functions can be created by the user. For example, a rate-of-frequency change or a rate of- voltage change function can be created. The relay provides circuit-breaker control, additional primary switching devices (grounding switches, transfer switches, and isolating switches) can also be controlled from the relay.

Automation or PLC logic functionality is also implemented in the relay. The integrated programmable logic (CFC) allows the user to add their functions, e.g. for the automation of switchgear. The user is also allowed to generate user-defined messages.

The communication module is independent of the protection.
