MI 3280 Digital Transformer Analyser
High Voltage Insulation / Continuity / Earth
The MI 3280 Digital
Transformer Analyser is a
portable, battery (Li-ion)
powered test instrument
intended for diagnosing of
turn ratio, phase deviation,
excitation current and winding
resistance of single and three
phase transformers. It has
an excellent IP protection:
IP65 (case closed), IP54
(case open) allowing the use
of the instrument in harsh
environments. The operation
is straightforward and clear
to enable the user to operate
the instrument without the
need for special training. For
advanced users the AUTO
SEQUENCES and visual tests
are available.
MEASURING FUNCTIONS
Available functions and features offered by the
Digital Transformer Analyser:
• Turn ratio measurement of single and three
phase transformers;
• Phase deviation between high voltage and
low voltage winding;
• Excitation current;
• Winding resistance measurement of single
and three phase transformers (Power
Transformers up to 1,6 MVA).
KEY FEATURES
• A 3.4'' color LCD display with touch screen
offers easy-to-read results and all associated
parameters.
• The operation is straightforward and clear to
enable the user to operate the instrument
without the need for special training.
• Test results can be stored on the instrument.
