Three-Phase Vacuum Recloser Offers Single-Phase Tripping

ABB has released the 38kV GridShield, a three-phase vacuum recloser with single phase tripping capabilities. Equipped with the RER620 Intelligent Electronic Device (IED), the 38kV GridShield recloser expands the GridShield portfolio.

The GridShield recloser was released in 2011 for 15-27 kV design. Rated for up to 10,000 operations and with modular pole assembly, the GridShield offers the flexibility to function as a recloser, sectionalizer, or automated load break switch. The GridShield combines ABB’s recloser with the advanced capabilities of the RER620.

The RER620, part of the ABB Relion family of controllers, has integrated loop control and comes standard with fully implemented IEC 61850 and GOOSE messaging features. Included in the RER620’s extensive set of protection functions is inrush detection, suitable for use in distributed generation applications and high impedance fault detection for downed conductor detection. Other advanced features include the powerful PCM600 tool suite and web-based HMI for quick and software-free IED configuration and record downloading.
