1 Introduction
1.1 General
The Precision Oil and Solid Dielectric Analysing System is designed for measurement of liquid
and solid insulating materials with a very low dielectric losses (Dissipation Factor and Power
Factor) of high voltage insulating material (e.g. Transformer Oil).
The instrument works on the principle of a combined bridge-vector-meter and is capable of
analysing capacitive and dissipation factor (tan

) as well as DC-Resistivity with outstanding
accuracy and stability.
The Graphical User Interface of the instrument is highly intuitive, focussed on convenience with
built-in useful programs (e.g. pre-programmed procedures according the standards) and uses a
large colour touch screen as the input device. The operator can choose between manual or
automatic modes. While the manual mode provides quick measurements, the automatic test
mode supports complete automated test sequences according the standards.
