Study Highlights Need to Re-Evaluate Railway EMC Standards
As part of a recently-completed European Union study on the effects of multi-source electromagnetic interference on trains, a British consulting company has helped redesign the way that conformance to railway electromagnetic compatibility (EMC) standards is determined. The project in question, a two-year study known as TREND (Test of Rolling Stock Electromagnetic Compatibility … [Read more...]
Sinusoidal Wave Filter Overcomes Interference Problems to Reduce Cable Costs
REO-USA has introduced the 400V three-line CNW933 sinusoidal filter range as an equally robust yet more cost effective solution to shielded cables. The cost of cables is rising in manufacturing as the result of the need for lengthy shielded cable to tackle attenuation and electromagnetic compatibility (EMC) issues. Compounded by increasing commodity prices, this is leading … [Read more...]
