ntroduction
1.1 Product description
IDAX instruments are very compact and are used
together with an external PC. IDAX 322 has built-in
2kV amplifier (VAX 020) for environments with high
level of interferences. The IDAX 350 has a built-in
computer but can also be used with an external PC.
IDAX 300/322/350 provides an accurate and reliable
condition assessment of insulation in transformers,
bushings, generators and cables. The IDAX system
maximizes the outcome of maintenance activities
allowing for load and service life optimization.
IDAX 300/322/350 instruments are small, light and
fast. It maintains excellent accuracy and ability to
provide reliable data using true AC DFR (Dielectric
Frequency Response), also known as FDS (Frequency
Domain Spectroscopy), for reliable test results in
high interference environments. The software makes
testing both easier and faster, allowing transformer
moisture and oil assessment in about 23 minutes
(20°C).
IDAX measures the capacitance and tan delta/power
factor of the insulation between power transformer
windings at multiple frequencies. Analyzing the
results using modelling technique makes it possible
to assess the moisture level in the solid insulation,
oil conductivity/tan delta and power frequency tan
delta at reference temperature (20°C). The test can
be performed at any temperature as the temperature
dependence of the dissipation factor can be
estimated.
