Hioki CT6872 AC/DC Current Sensor

Hioki’s pass-through type AC/DC current sensors can be connected directly to Hioki Power Analyzers and Memory HiCorders. Also, it can be connected to Power Meters, Oscilloscopes, DMMs, etc. by using an optional sensor unit.
The CT6872 has a frequency bandwidth of DC to 10 MHz and a rated current of 50 A. It is used for R&D, quality evaluation, manufacturing, and maintenance in markets such as wireless charging systems, inverter motors for industrial equipment, power conditioners for PV, and quick charging facilities for EVs.

Use with an instrument with a high input impedance of 1 MΩ or higher.

Key Features

  • Combined accuracy with HIOKI power analyzer PW8001, PW6001 and PW3390 is specified. For details of combined accuracy, refer to the instruction manual.
  • Wide-bandwidth DC to 10 MHz excellent frequency characteristics
  • Applications in the fields of electric and hybrid electric vehicles
  • Wide operating temperature range(-40°C to 85°C) fit for automobile applications
  • Ideal for evaluation of solar power generation and fuel cells to measure battery charge and discharge and the secondary side of inverters
  • For observing waveforms to be used with the oscilloscopes or Memory HiCorders (use with Sensor Unit)

Unparalleled technology driving the evolution of current measurement

High-accuracy sensors uses the “zero flux method (flux gate detection type).” High-frequency currents are detected with the winding (CT method), and DC to low frequency currents are detected using a “flux gate.”

Flux gate detection

Flux gate detection delivers outstanding linear properties, and can measure currents of a wide range of magnitudes with high accuracy.
The fluxgate components used for DC detection have very low offset over a wide temperature range due to their operating principle, resulting in high accuracy and excellent temperature stability. It is ideal for measurements that require high accuracy, such as Power analyzers and Power meters. It can be used for measurement such as inverter efficiency, inverter output power, reactor/transformer loss, and long-term DC measurements.

Wide frequency band

The CT6872 has a frequency bandwidth of DC to 10 MHz, which is top-class for a 50 A rated pass-through sensor. In combination with the Power Analyzer PW8001, high frequency and low power factor power can be accurately measured.

Automatic Phase Correction function

To accurately measure high frequency and low power factor, it is important to correct phase errors. The PW8001 automatically acquires and corrects the phase of the current sensor with 0.001°resolution, bringing out the best performance of the current sensor without any effort.

Automatic detection capability for even greater convenience

Automatic current sensor detection by Power Analyzer PW8001

The current sensor is equipped with a memory (I2C-EEPROM).
When the current sensor is connected to the Power Analyzer PW8001, the phase correction data, rated current, sensor’s model name, and serial number are automatically recognized by the instrument.

In the past, phase correction values had to be entered manually.
However, thanks to the automatic detection system of current sensor information, forgetting settings and typing errors are eliminated, allowing for more accurate power calculations.
