IEC/TR 61869-102:2014(E): Instrument Transformers – Part 102: Ferroresonance Oscillations in Substations with Inductive Voltage Transformers
From the International Electrotechnical Commission webstore: "IEC/TR 61869-102:2014(E) provides technical information for understanding the undesirable phenomenon of ferroresonance oscillations in medium voltage and high voltage networks in connection with inductive voltage transformers. Ferroresonance can cause considerable damage to voltage transformers and other equipment. … [Read more...]
Wideband High-Power Notch Filters Reduce Cosite Interference
MtronPTI, a manufacturer of custom RF/microwave filters and frequency control products, has released the new LF9454 and LF9455 GPS band reject filters designed to reduce cosite interference from jamming systems. “Battlefield success starts with controlling the electromagnetic spectrum; but electronic countermeasures – jammers – can drown out sensitive GPS receivers on the same … [Read more...]
PCB Analyzer for Impedance Testing in Manufacturing
Agilent Technologies has introduced the E5063A PCB Analyzer for printed circuit board impedance testing in manufacturing. Tighter impedance tolerance is a direct result of increasing data rates, the company says, and more accurate impedance test solutions for PCB manufacturing are now required to achieve signal integrity. To meet that demand, the E5063A PCB Analyzer offers … [Read more...]
