Flexible DNPIDs make OSM Recloser a Simple Replacement for Brownfield Switchgear Sites

NOJA Power OSM Recloser

With installations in over 106 countries worldwide, NOJA Power’s OSM Recloser is among the key switchgear of choice for overhead lines protection and control.

The global energy transition is fueling upgrades to the distribution grid, where older equipment is replaced by devices designed to handle the bidirectional power flow of distributed renewable energy sources.

NOJA Power’s OSM Recloser is a device of choice for replacing aged legacy equipment. Not only can the OSM Recloser manage bidirectional power flows, it can be configured to match the traditional Supervisory Control and Data Acquisition (SCADA) point lists.

Also known as DNPIDs when used with Distributed Network Protocol (DNP3) SCADA implementations, this flexible configurability of an OSM Reclosers’ point map allows it to be a direct replacement for legacy equipment.

Many legacy devices had fixed points list. With those devices, they connected via DNP3, but the lists of information that was returned was fixed. This is not the case with an OSM Recloser.

OSM Reclosers have fully customizable SCADA points lists (DNPIDs in the DNP3 communications protocol), allowing OSM Reclosers to appear identical to the outgoing asset. This means no costly modifications are required at the control center.

“Our DNP3 implementation is so flexible every single digital and analogue point can have its ID customized and be enabled or disabled so it does not transmit at all,” says NOJA Power Group Managing Director Neil O'Sullivan.

“With this flexibility our device profile can be configured identical to legacy equipment to make it a drop-in replacement and provide improved data at your choice.”
