Can relay protection be reset online

Yes, many modern relay protection devices can be reset online or remotely using software, communication protocols, or dedicated remote reset hardware.Remote Reset Options

1. Digital Communication and Software Control Certain digital protection relays, such as ABB's digital substation relays, can be monitored and configured through platforms like ABB Relays-Online. Registered users can access tools to program, configure, and in some cases, reset relays via software interfaces like PCM600, allowing remote management without physically interacting with the device . Similarly, Schneider Electric's SEPAM relays can be reset remotely using Advanced UMI, SFT2841, or third-party supervisory software via communication channels such as SMS or SCADA systems . 2. Remote Reset Hardware For thermal overload relays (e.g., Tesys LRD series), remote reset can be achieved using:

  • Auto-reset function, which automatically resets the relay after a fault.
  • Remote push-button control, connected via a short flexible cable to the relay.
  • Electrical reset devices, which send a voltage pulse to reset the relay coil remotely . These methods allow operators to reset relays without opening panels or manually pressing the reset button, improving safety and operational efficiency. 3. Logic-Based Reset Some advanced relays, like the SEPAM Series 80, support programmable logic functions (e.g., "V_Clear" and "V_Reset") that can be configured to automatically clear alarms and reset the relay under specific conditions . This is particularly useful for managing nuisance alarms or frequent resets in automated systems.
Considerations
  • Not all relays support online or remote reset; older or simpler models may require manual intervention .
  • Remote reset typically requires proper communication setup, secure access, and sometimes additional hardware.
  • Safety protocols must be followed to prevent unintended operations when resetting relays remotely, especially in high-voltage or critical systems. In summary, modern protection relays can often be reset online, either through software interfaces, communication commands, or dedicated remote reset devices, but the exact method depends on the relay type and system configuration .
