Electrical Power Measurements up to 100 kHz

Abstract Traditionally, AC power meters have been calibrated at power frequencies of 50/60 Hz. However, power meter manufacturers offer instruments with much higher power measuring bandwidths. This is because many applications consume power at higher frequencies, which go up to 100 kHz. These applications include: • Switching-mode power supplies, • High-frequency electronic lighting ballasts, • Soft starters in motor control systems, • Frequency converters in traction applications. Measurements of power at high frequencies have been lagging as well as the development of power meters to address the above applications, and few national laboratories provide traceable calibrations of up to 100 kHz. Without this capability, there remains doubt over the validity of the high-frequency specifications of power meters and power analyzers. The guaranteed accuracy and precision of Yokogawa’s instruments results from the fact that Yokogawa has its own European Standards Laboratory at its European headquarters in The Netherlands. This facility was the first industrial (i.e. non-government or national) organization in the world to offer accredited power calibration, at frequencies up to 100 kHz. The ISO/IEC17025 accreditation (RvA K164) demonstrates the international competence of the Laboratory.
