Description
ROF has oil insulation with mineral or vegetable oil. RGF is gas-insulated for outdoor switchyards, RGK is installed in GIS. The wide frequency band makes harmonics and transients visible, and the DC component makes the dividers suitable for HVDC. The low-level output signal is fed to digital meters and power quality analysers.

Questions and answers
What is the frequency band of the ROF, RGF, RGK dividers?
From DC to 30 kHz, so they are suitable for power quality measurement and HVDC.
Which version should be chosen for GIS?
RGK. For outdoor switchyards there are the gas-insulated RGF and the oil-insulated ROF.
Can a divider with vegetable oil be ordered?
Yes, the ROF is made with mineral or vegetable oil for 72.5–550 kV.
