Automatic Smart Grid Solutions – Pioneering Smart Grid Technology
The EW Series automatic recloser with advanced solid insulation technology – the perfect solution for modern power distribution systems, ready to integrate into the future smart grid.
— KEY FEATURES —
Built with solid epoxy resin insulation and vacuum switching technology, the EW Series eliminates the need for additional remote terminal units, power supplies, or enclosures. The integrated RTU and communication ports are included as standard equipment, significantly reducing both installation and operating costs. The stainless steel enclosure ensures long service life with minimal maintenance requirements, while DSA/SCADA compatibility enables remote control and monitoring capabilities.
— BENEFITS —
The integral protection relay ensures fast fault clearance while monitoring line current and voltage without additional measurement devices. This data enables forward planning and optimization of existing feeders. Designed for pole mounting with complete mounting brackets included, the EW Series offers simple commissioning through software configuration or operator interface.
