TMDRA 100
Accessory for DIRANA

The TMDRA 100 is an accessory for OMICRON's DIRANA. It
simulates typical dielectric response curves of power transformers
and can be used to train users on the software even if no real
test object is available. The TMDRA 100 is a demonstration box
especially designed for verification, it can not be used for the
calibration of the DIRANA.
The TMDRA 100 can be used to perform two-channel
measurements on-site or in the laboratory, and replaces the
'device under test'. It is directly connected to the DIRANA, using
the standard color-coded DIRANA cables. The sockets for the
input signal as well as the two-channel signal are clearly marked
for ease of use. The settings in the DIRANA software are the
same as for moisture assessment of real power transformers.
