OMICRON Electronics DIRANA

 OMI-DIRANA Dielectric Response Analysis and Moisture Test Set


The  OMI-DIRANA determines the dielectric properties as a function of
frequency.
It measures the dissipation factor and capacitance of insulation systems like
rotating machines.
It is used to determine the moisture content in oil-paper insulation for the
following applications:
1-Power transformers
2-Paper-mass insulated cables
3-Bushings
4-Instrument Transformers (CTs/PTs)

Water can cause dangerous effects for oil-paper insulation, it decreases the
dielectric withstand strength, accelerates aging of the paper insulation and
causes the emission of gas bubbles at high temperatures. Thus knowledge about
the moisture concentration is of utmost importance for the equipment operator.

The  OMI-DIRANA analyzes the dielectric response for determination of the
moisture content in the paper of oil-paper insulation. For this purpose, the
software uses a scientifically proven database to compare the measure values.
This is done completely automatically, only the oil temperature needs to be
entered.
