values. The product is designed solely for use in electrical energy systems
and facilities.
Bushing monitoring The optional bushing monitoring function is used to monitor capacitance-
graded bushings on power transformers in the U
m
= 123...420 kV voltage
levels (with voltage levels up to 765 kV on request). You can use this func-
tion to detect breakdowns at partial capacitances in the bushing and to moni-
toring aging in the bushings.
