Desde 1889, a Megger e suas empresas antecessoras têm ajudado engenheiros elétricos a manter a energia através do desenvolvimento e da fabricação de ferramentas portáteis para teste e medição.

 Sinds 1889 ontwikkelt en produceert Megger, net als zijn voorgangers, draagbare test- en meetapparatuur waarmee elektrotechnici ononderbroken stroomvoorziening kunnen verzekeren.

This application note explains Security Factor (FS) and Accuracy Limit Factor (ALF), what compensated FS and ALF mean, and how it is implemented in the TRAX software. To assist in the explanation of compensated FS and ALF, the basic operation principle of a current transformer will be described.

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.

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 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.
