Description
CT6876A AC/DC Current Sensor for Inverter and EV Testing
The CT6876A AC/DC Current Sensor is engineered to meet the demands of next-generation power electronics where both high current and high speed are critical. Designed as a pass-through type sensor, it supports accurate measurement of currents up to 1000 A, making it an ideal solution for EVs, hybrid vehicles, industrial inverters, and renewable energy systems.
Zero Flux Detection
At the heart of the CT6876A AC/DC Current Sensor is Hioki’s advanced zero flux method, which combines flux gate detection for DC and low-frequency currents with CT detection for high-frequency components. This approach ensures excellent linearity and extremely low offset, even over wide temperature ranges. As a result, users benefit from consistent accuracy during long-term measurements such as battery charge and discharge evaluation or inverter efficiency testing.
Wide Frequency Performance
The CT6876A AC/DC Current Sensor delivers a wide frequency response of DC to 1.5 MHz for amplitude and DC to 1 MHz for phase, which is exceptional for a 1000 A rated sensor. This wide bandwidth allows precise capture of fast-switching waveforms commonly found in modern inverter and power conversion systems.
High Noise Resistance
Accurate measurement in noisy electrical environments is made possible by a reinforced shielding structure. This design minimizes the impact of external noise, enabling reliable detection of current signals that would otherwise be obscured. The result is dependable data even in high-voltage and high-current test setups.
Smart Integration
When connected to the Hioki Power Analyzer PW8001, the CT6876A AC/DC Current Sensor automatically transfers sensor information such as phase correction data, rated current, model name, and serial number. This automatic detection reduces setup time, prevents configuration errors, and improves overall measurement confidence.
Demanding Environments
With an operating temperature range of -40°C to 85°C, the CT6876A AC/DC Current Sensor is built for harsh environments found in EV charging facilities, industrial plants, and renewable energy installations. Its durability and precision make it a dependable tool for both laboratory and field applications.
