Yokogawa Electric Corporation (横河電機株式会社, Yokogawa-denki Kabushiki-kaisha) is a Japanese multinational electrical engineering and software company, with businesses based on its measurement, control, and information technologies.
The network analyzer installed at Massachusetts Institute of Technology (MIT) grew out of a 1924 thesis project by Hugh H. Spencer and Harold Locke Hazen, investigating a power system modelling concept proposed by Vannevar Bush. Instead of miniature rotating machines, each generator was represented by a transformer with adjustable voltage and ...
Electric power quality is the degree to which the voltage, frequency, and waveform of a power supply system conform to established specifications. Good power quality can be defined as a steady supply voltage that stays within the prescribed range, steady AC frequency close to the rated value, and smooth voltage curve waveform (which resembles a sine wave).
Power Quality Analyzers, often referred to as Power Analyzers, make a digital recording of the voltage and current waveform (typically either one phase or three phase) and accurately calculate true power (watts), apparent power (VA) power factor, AC voltage, AC current, DC voltage, DC current, frequency, IEC61000-3-2/3-12 Harmonic measurement ...
The file format is designed to represent all power quality phenomena identified in IEEE Std 1159, [5] which is a recommended practice on monitoring electric power quality. PQDIF can be used to represent other power related measurement data and is extensible to other data types as well.
ZVA40 vector network analyzer from Rohde & Schwarz.. A network analyzer is an instrument that measures the network parameters of electrical networks.Today, network analyzers commonly measure s–parameters because reflection and transmission of electrical networks are easy to measure at high frequencies, but there are other network parameter sets such as y-parameters, z-parameters, and h ...
