HSL5510U Line Protection Measurement and Control Device
Application Scope
The HSL5510U line protection and monitoring device is suitable for line protection, measurement and control mainly based on current-type protection at voltage levels of 110kV and below. It can be installed locally on switchgears in a distributed manner or centrally in panels. It is equipped with communication interfaces and can form an automation system together with other protection and automation devices via the communication interfaces.
