Testing bushings with IDAX
Bushings are devices intended to safely transmit electrical energy through a grounded barrier. A well-known bushing application is carrying high voltage in a conductor into the grounded tank of a power transformer.

A novel approach to DFR measurement speed and fidelity
DFR (Dielectric Frequency Response), also known as FDS (Frequency Domain Spectroscopy), is a measurement technique in which capacitance and losses (dissipation factor/tan delta or power factor) are measured over multiple frequencies to assess insulation condition in test objects, such as power transformers, bushings, and current transformers (CTs). DFR technology is a long-established test procedure in laboratories that, in an innovative effort by Megger, was adapted for field use through the IDAX range of instruments.

Infrabel – Infrastructure Belgian Railways
Infrabel is a state-owned company responsible for the national railway infrastructure in Belgium. The company operating the trains is NMBS.Belgium has one of the densest rail networks in the world. This small country has 551 railway stations and 3064 km of electrified track. More than 200 million passenger rides are counted on an annual basis.Electrification started back in the fifties. At that point in time, it was decided that the Belgian rail tracks would be electrified with 3000 V DC, and other countries, such as Spain and Italy, did the same. Today, Infrabel has more than 2000 DC high speed breakers in operation from different manufacturers including Acec, Ansaldo (Micro Elettrica), AEG, and Secheron.The North-West region decided to purchase 6 BALTO 8000 systems to test their breakers and relays.

Case study: What is melting here? Time for an SFRA test
This case study has been generously supplied by the Hitachi Energy Service group in Sweden. A 22 MVA, 10.5 kV/276 V (voltage regulation from 336 to 216 V), Diii furnace transformer, operating in heavy use for many years at a steel melting plant in Europe was subjected to a complete series of tests after a sudden failure during operation. The service contractor evaluated the electrical and dielectric condition of this transformer. During service, this type of transformer has its secondary winding connected externally in a Delta configuration through a high current bridge.
