IEC 61850 to standard stworzony do komunikacji w stacjach elektroenergetycznych i poza nimi. Zagadnienie "testowanie" było tym, które budziło najwięcej obaw od początku procesu standaryzacji i jest ważne w praktyce. Artykuł ten opisuje nowe podejście z nowymi możliwościami. Rozwiązanie wymaga usługi klienta w oprogramowaniu testowym.
Phasor Measurement Units (PMUs) are getting increasingly popular. Major incidents in the near past, such as the big blackouts in 2003 in the northeast of the USA and in Italy, have raised the interest in all means that support the observation of the condition of the electrical power network, assessing system stability, and predicting problems. PMUs are perceived to be valuable tools for this. The...

A two-color Nd:LSB microchip-laser that simultaneously emits at 1061.3 nm and 1063.9 nm is used for photomixing. Since LT-GaAs which is typically utilized for photomixing cannot be excited efficiently with wavelengths exceeding 1 μm, LT-GaAsSb with a bandgap energy designed to match the laser emission is used here for the first time. With this system THz radiation at 0.7 THz is generated and detected...
