The LFR is ideal for power quality applications. It has a small, predictable phase error, for power measurements at 45/65Hz. The wide bandwidth allows accurate measurement up to and even above the 400th harmonic.
The LFR is very linear with current magnitude and the 10:1 switch selectable current range enables measurement over a wide dynamic range.
Power (Quality) Measurements
The LFR has market leading low frequency performance, optimised to give minimal phase error from 45Hz to 20kHz and the lowest possible noise floor. It can be used with frequency analysers, digital multimeters and oscilloscopes to perform a thorough power quality audit. The thin, flexible coil is easy to install even where conductors have been tightly bundled or space is restricted making it easy to identify sources of power quality disturbances.
Leakage and Ground Currents
When used in combination with a digital multimeter the LFR can be used to detect ground and leakage currents. The flexible coil is easy to install around large individual and multiple conductors as well as conduit trunking. The LFR coil can be supplied in standard lengths up to 1m and two turns can be made around a conductor (for coil lengths >=700mm only) to double the measurement and improve the SNR ratio.
