Multi-phase power analyzer from Tektronix uses Spiral Shunt

Tektronix has announced its new precision multi-phase Power Analyzer PA4000, which uses something called Spiral Shunt design. The PA4000 uses two Spiral Shunts on each channel - one for current measurements up to 1 A, for precise low-current measurements, and one for current measurements up to 30A, for higher-current measurements. PA4000 uses high-speed digital signal processing algorithms to track power cycles accurately in the presence of transients and noise.

Tektronix explains power analyzers such as the PA4000 are used by power electronics engineers for designing, testing and validating power electronics devices, primarily in multi-phase applications. Key industries include motor drives, electric propulsion, backup power, alternative energy, and high-efficiency lighting. Many of these engineers work on designs that are subject to government regulations and customer requirements that dictate efficiency and the amount of harmonic distortion or other "line pollution" that may be imposed on the power grid, as per Tektronix.

"Tektronix brings strengths to this segment that no other supplier of power analyzers can match," said Curt Willener, general manager, Power Analyzer Product Line, Tektronix. "We offer the most complete end-to-end test and measurement solutions for debugging and optimizing power-electronics designs, all backed by our worldwide network of account managers, distributor partners, and service sites."

PA4000 features precisely-matched inputs, wide input ranges and advanced signal processing to deliver consistently high measurement accuracy in all types of measurement environments, according to Tektronix.

The Tektronix PA4000 Power Analyzer to be available worldwide starting in April 2013 with US MSRP starting at $10,500.
