HICOS CVS
Combined current and voltage sensors, measurement voltage sensors, voltage indicator sensors. Tested at CESI according to IEC Standards. Patent pending.
Up to 36 kV / 630 A / 25 kA
Description
The HICOS CVS current and voltage sensors make the passthrough connection between the line connection terminals and the switchgear equipment in a single monobloc (one per phase). In the insulating block they incorporate the circuits of the primary and secondary current and voltage measurement signals. They are manifactured without a ferromagnetic circuit: the current sensor is made through the use of an air-wound coil (Rogowski coil); the voltage sensor is made by a capacitive circuit with voltage divider.
Fields of application
HICOS CVS sensors are normally used in HICOS GIS secondary distribution gas insulated switchgear, for the construction of electrical distribution and MV / LV transformer substations. They are suitable for use in utilities, conventional and renewable energy production plants, light industry, transport, and the tertiary sector.
