A simple and affordable way to evaluate the effectiveness and performance of an electrical system is with current and voltage sensors.
Predicting component failures, planning preventive maintenance, and reducing downtime are all made possible by real-time current and voltage sensors. By using a direct connection, a conductor through-hole, or a clamp-on/split-core, DC sensors enable the measurement of DC currents.
AC/DC is used to detect both AC and DC current. Without disrupting the circuit in any way, current sensors provide passive current measurement. They surround the conductor who’s current we are attempting to measure.
The global AC/DC sensor 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 introduces the CT6877 2000 An AC/DC Current Sensor. Pass-Through Current Sensors are Perfect for Evaluating EV/HEV Inverters that Show Increasingly Large Currents since they Measure 2000 A AC/DC with High Precision.
Hioki is happy to announce the release of the CT6877 AC/DC Current Sensor, a pass-through current sensor that can precisely measure huge currents up to 2000 A 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 of 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. The CT6877 is one of the best-performing pass-through sensors with a 2000 A rating, and its frequency range of DC to 1 MHz makes it perfect for monitoring currents switched at high frequencies by SiC/GaN components.
The most precise and widest bandwidth current sensor in the market, the high current 65 Amp MCx1101 Current Sensor was unveiled by ACEINNA. This highly accurate, wide bandwidth AMR-based (Anisotropic Magnetoresistive) current sensor is perfect for a variety of next-generation power systems and applications.
It is available in 3.3- and 5-Volt versions. Units can now be ordered for volume shipments and sampling. Compared to competing products, ACEINNA’s MCx1101 current sensors offer a significantly higher DC and AC accuracy and dynamic range. They are also fully integrated and bi-directional.
Power system designers can take advantage of the higher speeds and smaller components made possible by wide band-gap switches thanks to the MCx11-quick 1’s response and high bandwidth, which make it ideal for fast switching SiC and GaN based power stages. Response time for an output step is only 0.3us. Response time for over current detection is a quick 0.2us.
Five new wireless voltage and current metres have been released by Swift Sensors (www.swiftsensors.com), a provider of wireless industrial IoT sensor solutions, for monitoring AC and DC power systems. In order to maximise efficiency and cost savings, the sensors are used in facilities and manufacturing plants to monitor the power consumption of buildings and equipment.
Users now have the option to monitor consumption at the site, circuit, or machine level thanks to new current and voltage sensors. Facility managers can decide wisely how to conserve and lower power usage throughout their facility with this visibility and insight.
Eaton’s E57 series of 2-wire inductive proximity sensors with either AC or AC/DC sourcing offers application flexibility. Eaton’s E57 2-wire AC and 2-wire AC/DC sensors. The Global and Premium + series are further subdivided into this group of sensors.
A 2 m cable, a microconnector, and a nanoconnector are among its terminations. DC units have a 100 mA load current rating for power handling, and AC units have a 200 mA rating. Control system design flexibility is maximised by a wide range of connector and output circuit options. Extreme temperatures or environments with high-pressure washdown are perfect for the sturdy design.
