Precision Current Sensors are engineered to safely and accurately scale down high AC/DC currents for direct input into a power analyzer. This ensures ultra-precise, stable measurement without compromising safety or analyzer performance.
Our current transformers and fluxgate sensors are built for accuracy, unlike current probes, which are ideal for oscilloscopes and DAQs but not suited for precise power analysis. Sensors also enable non-invasive measurement of the DUT: clamp-ons require no rewiring, through-hole types only a temporary rewire, while direct analyzer input demands a dedicated series connection.
Covering ranges from 60 A to 5000 A, our sensors deliver exceptional linearity and phase accuracy, making them ideal for EVs, renewable energy, semiconductors, and advanced R&D applications. With Yokogawa, engineers can measure high currents with confidence and clarity.
In some power measurement applications, the current in the device under test is higher than what can be applied directly to the power analyzer current input terminals. Current transformers are used to step down high AC and DC currents to a lower level that can be measured directly by the power analyzer. These systems safely step down currents while preserving the highest accuracy.
Industry leading high precision, high current AC/DC split core measurement. Compatible with power analyzers and waveform measurement instruments.
