ATL Transformers Academy
ATL design and deploy leading magnetics to the rail network and its principle contractors. We offer the highest specifications on the market while maintaining competitive pricing against alternative legacy technology. Our magnetics are approved for use by Network rail, Crossrail, London underground and are widely used to support Designers, Route asset manager, maintainers & Installers. As the preffered solution in rail ATL’s New generation of magnetics, eco-rail® is raising the bar on quality and performance, delivering unprecedented levels of weight/size reduction, ergonomics, Carbon reduction and safety.
Low voltages are rated voltages that are not higher than 1000 V AC.
High voltage is defined as a voltage, that is higher than a low voltage of 1000 V. The maximum we are able to produce at the moment is at 50 kV AC.
The AC high voltage output has the following special characteristics: One terminal is connected to earth (minus pole, green/yellow connector) and the other terminal is connected to the high voltage side (plus pole or “hot side”).
Current is calculated with the power I = P/U and is usually given in [mA].
The frequency is at 50 Hz sinusoidal. For special fields of application, frequencies can be higher. We already built transformers with 20 kV and 1000 Hz.
The insulation test primary – secondary is done with 120% of the high voltage value.
High potential means a separation of a potential that is close to earth and a potential that is very high e.g. 20 kV or 100 kV over 0. The separating voltage is given in kV DC. The maximum we are able to produce at the moment is at 160 kV potential difference.
