Zelisko U/I sensors – for your permanent network monitoring
☑ High measurement accuracy | ☑ Good transmission behaviour of harmonics | ☑ Simple retrofitting of existing systems: The voltage sensor is based on the functional principle of the ohmic divider. The phase current sensor is an almost powerless inductive current transformer.
The current and voltage sensors were developed to equip medium-voltage switchgear in local network stations with accurate measurement technology.
The focus is on grid stations in urban, rural and industrial areas. The sensors are used for measuring, monitoring, protecting and detecting short-circuits or earth faults and determining their direction.
The compact sensors from Zelisko enable quick and easy retrofitting without major changes to the switchgear and grid infrastructure.
The equipment of the T-connectors with sensors depends on the application (original equipment or retrofitting), the size of the cable connection compartment of the switchgear and the local conditions.
