Pax Idax-300 tests transformer insulation

A Megger product story
Edited by the Engineeringtalk editorial team Apr 17, 2009

The Pax Idax-300 test set from Megger easily, quickly and accurately assesses the condition of the insulation in power transformers - a key indicator of future reliability and performance.

The test set is also suitable for assessing the insulation condition of bushings, cables, motors and generators.

Information provided by the PAX IDAX-300 test set is an important aid for optimising the service life of costly power transformers.

Information provided by the PAX IDAX-300 test set is an important aid for optimising the service life of costly power transformers.

The Idax-300 is based on frequency domain spectroscopy (FDS), also known as true dielectric frequency response testing.

This technique is now available in a self-contained, field-portable unit with USB and LAN communications, allowing convenient, remote-controlled testing, data retrieval and analysis.

By using FDS, which involves measuring the capacitance and tan delta/power factor of insulation at multiple frequencies, the IDAX-300 is able to evaluate the condition of the oil and solid insulation in a transformer.

This gives a much more comprehensive and dependable indication of the transformer's overall health than traditional test techniques.

FDS also allows tests to be performed at any temperature.

The IDAX-300 is complemented by software that allows moisture assessment of the insulation in a transformer to be completed in just 18 minutes.

Weighing less than 5kg and capable of operation from battery or any 50 or 60Hz supply in the range 90V to 265V, the IDAX-300 is suitable for use in the laboratory, the workshop or on site.

It is supplied as a complete kit, including the instrument itself, a set of 30ft cables, a hard transport case, a soft case for accessories, a software CD and a comprehensive user manual.
