AC Current Transducer

The AC Current Transducer is a high-precision current sensing device specially designed for AC current collection in power systems. It can monitor the current magnitude of distribution lines in real time, and provide reliable current data for protection, metering and monitoring systems. This product adopts electromagnetic induction principle and high-precision signal processing circuit, with wide measurement range, high accuracy and good linearity. It can accurately collect the full range of AC current signals from load current to short-circuit current, and can be used together with our switchgear such as circuit breakers and reclosers to realize accurate current sensing and fault judgment of lines. As one of the core sensing components in power systems, the AC Current Transducer is widely used in current monitoring and protection scenarios of various distribution systems.

In terms of product design and application adaptability, this AC current transducer adopts a through-hole structure design, with convenient installation. It does not need to disconnect the line and can be directly sleeved on the conductor, facilitating construction and maintenance. The equipment adopts low-power design, with stable and reliable operation and strong anti-electromagnetic interference ability, and can measure accurately in complex power electromagnetic environments. The whole is encapsulated with flame-retardant insulating materials, with good insulation performance, safety and reliability, high protection grade, and can adapt to various indoor and outdoor application scenarios. In response to the application needs of distribution network switchgear, we have optimized the aperture specification, measurement range and output interface of the product, which can perfectly match our circuit breaker and recloser products. We can also customize different current transformation ratios, accuracy grades and output modes according to customers' needs to meet diversified current collection needs.

Our professional technical team will follow up the customization process throughout the whole process, and communicate throughout the whole process from scheme design, sample testing to batch production, ensuring that the customized products fully match customers' equipment and project needs and meet diversified current collection scenarios.

Our factory was founded in 1996 and is the supporting unit of Henan Provincial Intelligent High-Voltage Sensor Engineering Technology Center. We have a professional sensor R&D and production team, with complete production capabilities from core packaging to finished product calibration. The plant is equipped with professional sensor production workshops and calibration laboratories, with advanced production and testing equipment, and a monthly production capacity of tens of thousands of units, which can stably accept various large and small batch orders. We have provided supporting current transducers for many domestic power equipment manufacturers and distribution network projects, and have rich experience in R&D and batch delivery of sensing equipment, with mature technology and stable product quality.

We have established a strict quality management system for sensors, and implement full-process quality control for this AC current transducer. Core magnetic cores and processing circuits have all undergone strict incoming inspection and screening to ensure stable performance. Each process in the production process is set with exclusive quality inspection nodes. Before delivery, finished products must pass full inspections such as accuracy calibration, linearity test, insulation test, and environmental adaptability test. A 100% full inspection system is implemented, and each product is accompanied by a calibration report. We support third-party metrological institutions for calibration and inspection to ensure that each delivered transducer has up-to-standard accuracy and reliable performance.
