• State-of-the-art measurement of moisture content, tan delta/power factor, and oil conductivity using DFR (Dielectric Frequency Response)
• Dedicated test procedures for power transformers, bushings, and current transformers
• Automated individual temperature correction (ITC) for accurate comparison with reference data/tests
• Reliable measurements even in high interference environments
• Fastest system on the market due to its novel and reliable combination of frequency and time domain measurement data
The IDAX300 and IDAX350 insulation diagnostic analysers are insulation diagnostic instruments based on DFR (Dielectric Frequency Response), also known as FDS (Frequency Domain Spectroscopy). DFR is a measurement technique in which capacitance and losses (dissipation factor/tan delta or power factor) is measured over multiple frequencies to assess insulation condition in test objects such as power transformers, bushings, and instrument transformers. DFR technology is an established test procedure in laboratories that Megger has adapted for field use in the IDAX range of instruments.
This IDAX series consists of:
• IDAX300: A compact and light three-channel input (red, blue, and ground), three-terminal (generator, measure, and guard) and one ammeter instrument for use with an external computer that runs the IDAX diagnostic software.
• IDAX300/S: Like the IDAX300, but with two ammeters for two simultaneous measurements.
• IDAX350: Like the IDAX300/S, but housed in a rugged and waterproof case together with an on-board computer that can also be used to control other Megger instruments.
