True RMS current transducer has a wide range of applications, especially in applications involving distorted signals, where they can accurately measure the effective value of complex, non-sinusoidal waveforms. Operating Principle of True RMS Current Transducer True RMS current sensors primarily utilize electromagnetic induction and the Hall effect to measure the magnitude of current. Electromagnetic Induction Method When current flows through a conductor, a magnetic field is generated around it. The true RMS current sensor measures the current magnitude by detecting changes in the magnetic field (such as changes in magnetic flux), essentially indirectly measuring the current by detecting changes in the resistance, capacitance, etc., of the coil. The core formula is: IS×NS=IP×NP Where IS is the secondary current, IP is the primary current, and NS and NP are the number of turns of the secondary and primary coils, respectively. This method has high sensitivity and is suitable for wide-range measurements. Hall Effect Method When current flows through a Hall element, a magnetic field perpendicular to the current direction generates a Hall voltage across the element, proportional to the current. The formula is: VH = k×I×B, where VH is the Hall voltage, k is a proportionality constant, I is the current, and B is the magnetic field strength. This method is renowned for its high accuracy and rapid response time, making it well-suited for applications that require precise results. Applications of True RMS Current Transducers Ensuring the Safe and Stable Operation of Power Systems True RMS current transducers provide critical data for short-circuit protection by continuously monitoring grid current fluctuations and abnormalities, effectively preventing equipment damage and fire accidents. Improving the Efficiency of New Energy Equipment In electric vehicles, true RMS current sensors are used in the battery management system (BMS) to precisely monitor charging and discharging currents, preventing overcharging and over-discharging and extending battery life. They also optimize motor drive control, reducing energy loss and ensuring efficient and safe vehicle operation. Industrial Automation In industrial applications, true RMS current sensors are used to monitor the current of motors, transformers, and other equipment, ensuring the stability and safety of production processes. In summary, true RMS current transducers play a crucial role in modern electrical systems. They are widely used across various industries.

The main differences between standard normal current (usually referred to as peak current) and RMS current lie in their definitions, measurement methods, and application scenarios. Definition and Measurement Method Peak Current: Peak current applies to all AC currents and refers to the maximum instantaneous value within a cycle, directly reflecting the highest point in the waveform. Peak current is approximately 1.414 times the RMS current. A Hall-effect current transducer (with a peak detection element) is typically used to detect peak current. RMS Current: RMS current reflects the effective value of an AC and describes its equivalent DC in terms of thermal effects. It is calculated by averaging the square of the current waveform and taking the square root. For sinusoidal current, the RMS value is the peak current divided by √2. Using a true RMS current transducer allows for fast and accurate RMS current measurements. Application Scenarios Peak Current: Peak current is primarily used in components such as motor drives, transformers, and power supplies, which are designed with peak current ratings to prevent failure or overheating during power surges or high demands. RMS current: RMS current is crucial for designing and analyzing AC circuits because it directly relates to the heating effect of current flowing through resistive loads. Both peak current and RMS current play important roles in electronics and electrical engineering. Their proper utilization ensures efficient and stable operation of electrical systems.
