Power Electronic Measurements LFR AC
A new LFR AC current probe with market leading low frequency performance has been introduced by Power Electronic Measurements Ltd (PEM). This compact, low cost, clip-around probe is both flexible and dual-range, while being optimised to give minimal phase measurement error at frequencies from 45Hz to 20kHz. This is a Rogowski current probe, similar to PEM’s highly successful CWT range, which covers 1Hz to 20MHz. The LFR unit is ideal for use as a general purpose power frequency AC current probe and can be used with oscilloscopes, acquisition cards, data loggers, power analysers and meters.
