功能

• There are even smaller protection relays and more protection units for connecting distributed power sources to the power system. • Distributed power sources are becoming increasingly popular, such as cogeneration systems that enhance overall energy efficiency and wind power generation that uses natural energy.
• This relay is a protective relay that protects systems and systems by detecting in-demand accidents in distributed power sources and power line accidents linked to distributed power sources.
• This relay satisfies the models and functions listed in the "Guidelines for System Interconnection Technology Requirements" issued by the Agency for Natural Resources and Energy, and the 20 or so models in the lineup allow us to construct an optimal protection system.
• Compatible with generators and power receiving end/private feeders.
• A selection of units with two relay elements.
• Each unit has a built-in operation time circuit that can be varied, making cooperative design easy.
• All models are equipped with a lock terminal for locking relays.
• The DSR reliably determines directionality even in the event of a short-circuit accident where the voltage suddenly drops to zero.
• Uses 2-stage plover terminal block with easy wiring cover.
