Megger Group is acquiring Pax Diagnostics of Sweden, a provider of transformer testing and insulation diagnostics products. The Pax IDAX range of Dielectric Frequency Response Analyzers are designed for measuring moisture in power transformers as well as testing insulation material in various power system products. The IDAX300 represents the latest generation in the well-known IDA/IDAX range of instruments and represents a breakthrough in terms of weight-performance ratio. With its optimized design, the test set is three times smaller and lighter and performs insulation characterization twice as fast as its predecessor IDA200.

The Pax FRAX range of Sweep Frequency Response Analysis (SFRA) products are designed for detecting electromechanical changes inside power transformers. The products have the highest measurement range and accuracy in the industry and fulfil all recent international standards and recommendations for SFRA testing.

“We have seen a growing demand for advanced diagnostic testing technology, and the inclusion of the PAX Diagnostics business enables Megger to provide a complete transformer test solution,” said Greg Wolfe of Megger. “The Pax product line coupled with the expert knowledge of the Pax staff enables customers to move toward predictive test regimes, potentially saving time and money as resources can be directed toward where they are needed most.”

“Megger is a natural choice for Pax,” said Peter Fagerström, CEO for Pax. “Our vision from the start of Pax four years ago was to be a top player in the international power transformer test equipment market. Our products fit perfect with the Megger transformer product portfolio and together we will create the strongest product line in the industry to address end user concerns”.

“The Megger brand will add confidence to the Pax products,” says Matz Ohlen, Marketing & Sales Director at Pax. “We invented the first DFR/FDS field instrument and now it will carry the Megger brand name, and will be supported through Megger sales and applications staff worldwide.”
