3 phase over/under voltage relay H3US, H3USN. Phase control of line voltage; Wide range input voltage; 35 mm cabinet with DIN rail; LED indication
Relay is used for over voltage protection and supervision in distribution systems. Relay is also used for overvoltage / undervoltage protection of Generators, Motors and Transformers. Design and principle The VHXm is a AC voltage measuring relay. Different versions are available for a) Fixed voltage Under / over voltage relay type VHXm The over- and undervoltage relay REU 523 is a secondary relay which is connected to the voltage transformers of the object to be protected. The unit continuously measure the fundamental wave of the phase-to-phase voltages of the object. This paper presents a new design for over/under voltage (OV/UV) protection scheme using Arduino microcontroller. The protection scheme is designed to protect the solid-state transformer (SST) branch of a Future Renewable Electric Energy Delivery and Management (FREEDM) system.
• AC Solid State Relay. • Zero switching. • Rated operational current: 50, 90 and 110 AACrms. • Blocking voltage: Up to 1600 Vp. before overloads and short circuit, which can damage output of device.
Over voltage and under voltage protective device protector relay with over current protection. Watch later.
