IDAX300-350 data sheet - .PDF file.

Megger has introduced the IDAX350 insulation diagnostic analyser, which integrates, in a single compact instrument, everything needed to carry out quick, accurate and comprehensive insulation condition assessment of power transformers, bushings, generators and cables. It is particularly suitable for on-site applications but is also a good choice for in-house use.

The instrument incorporates the test circuitry of Megger’s IDAX300 instruments and a computer with a large colour touchscreen. Together, these provide all the functionality needed for automated analysis — in a single test — of moisture content, oil conductivity and tan delta.

The tests can be carried out over a wide temperature range, and tan delta values, as well as oil conductivity, are automatically individually corrected by the instrument to reference temperatures of 20°C and 25°C respectively.

A typical test to determine the moisture content in the insulation of a power transformer, which is a key indicator of future reliability and performance, takes only about 22 minutes (1MHz). The test yields far more information than traditional tan delta testing at power frequency and make it possible, for example, to discriminate between a dry transformer with bad oil and a wet transformer with good oil.

Key features and benefits

  • Features include a robust enclosure and a convenient carrying handle
  • The device is said to be accurate and versatile
  • It uses true frequency domain measurement techniques that maximise interference rejection, ensuring that it gives fast and dependable results even in electrically noisy environments such as substations and switchyards
  • It features input circuitry that supports multiple test modes without the need to change test lead connections, and an extra current input channel that allows two completely independent measurements to be carried out simultaneously
  • The device can operate in conjunction with an external PC should this be preferred by the user
  • Software uses advanced modelling techniques and curve matching to produce dependable and easy-to-interpret results that include percentage moisture in solid insulation and individually temperature-corrected tan delta and oil conductivity values
