Megger IDAX 300 insulation diagnostic system

*Megger IDAX 300 provides accurate and reliable condition assessment of power transformers, bushings, generators and cables. The Megger IDAX 300 improves maintenance efficiency by optimizing equipment load and life. The IDAX-300 is three times smaller and lighter than its predecessor, the IDAX-206, but has the same ability to deliver reliable data. Advanced software makes testing easier and faster. *The Megger IDAX 300 measures capacitance and insulation loss between turns at a variety of frequency domain test points. This unique information provides insight into the condition of the oil and solid insulation and can be used to distinguish between moisture and other potential problems. Measurement is possible at any temperature.

Application Due to the aging of an entire generation of power transformers, today's electric power industry has faced serious problems, as transformer failures, their repair and related costs lead to significant economic losses. Transformers have become the most problematic elements of electrical networks. The need for reliable monitoring and diagnostic methods has led leading experts in this field to choose new technologies that can significantly increase the reliability and optimize the operation of each of the network elements [1]. The Megger IDAX 300 is one of the most advanced insulation diagnostic instruments based on the dielectric spectroscopy method. This method of analysis has so far only been used in the laboratory and IDA/IDAX is the first instrument to allow this method to be implemented in the field (1997). The Megger IDAX 300 device and the technique used in it have been confirmed by operation in industry in various countries of the world over the past ten years. *One of the most important applications of IDAX is the determination of the aging or moisture content of transformer insulation, as the presence of moisture in the insulation greatly accelerates the aging process. Moisture can also cause bubbles to form between the windings, leading to crashes. IDAX provides the ability to reliably estimate moisture content in a single test. This test can be performed at any temperature and takes less than 18 minutes. *Repair and/or replacement decisions should be based on knowledge of the condition of the insulation and the anticipated load on the equipment. Adding several years to the standard operating life of a transformer, generator and cable by optimizing operating (loading) conditions based on reliable diagnostic data will allow the owner of the equipment to significantly save on maintenance. *The technique can also be used to assess the condition and aging of the insulation of bushings, current transformers and circuit breakers. *Numerous ongoing research projects at institutes and universities around the world add to the experience and value for Megger IDAX 300 users.
