In industrial contexts, DC electrical current is measured using DC current sensors. They are designed to offer precise current measurements in DC applications like renewable energy or transportation because of their accuracy and endurance.
The magnetically permeable core that concentrates the magnetic field of the current conductor is necessary for the sensor to function. A steady current (in one plane) activates the Hall effect device, which is positioned inside the core and at a right angle to the concentrated magnetic field.
The Global DC sensors market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
Hioki is happy to announce the release of the CT6877 AC/DC Current Sensor, a pass-through current sensor that can accurately measure huge currents up to 2000 Amp AC/DC.
In order to properly assess inverters (devices that convert DC to AC) used in electric vehicles (EVs) and hybrid vehicles (HEVs), a class of devices that continue to move toward ever larger currents and higher-frequency switching, the sensor must be able to measure large currents and have a wide frequency band and excellent noise resistance.
The majority of large currents are split across two and four wires. Due to the devices’ inadequate aperture size and current ratings, it was previously essential to test wires separately using numerous current sensors.
In such configurations, the capabilities of the optional Sensor Unit CT9557 allowed for the addition of the measured values from the sensors and the output of the result as a single signal.
The CT6877 can accept four wires with an outside diameter of 31 mm because to its big, 80 mm aperture (equivalent to a cross-sectional area of 250 mm2). In this method, wires carrying up to 2000 A can be collectively measured by a single sensor.
