Industry Information

Idustrial Digital Panel Meter

The industrial digital panel meter is an essential measuring instrument widely deployed within electrical cabinets, control panels and automated industrial systems. Designed for panel mounting, this multi-channel ammeter adopts high-brightness red LED digital displays to present real-time AC current readings clearly at a glance. With three independent display windows, the device can monitor three groups of current signals simultaneously, which greatly saves installation space and simplifies the wiring layout for power monitoring projects.

Dc Current Transducer

A DC current transducer is a precision electronic device designed to convert a direct current input signal into a standardized, isolated output signal for measurement, monitoring and control systems. It bridges high-power DC circuits and low-voltage acquisition units widely used in power electronics, renewable energy, industrial automation and battery management systems.

Direct Current Transformer

A direct current transformer (DCT), also known as a DC current transformer, is a specialized instrument transducer designed to measure direct current. Unlike conventional AC transformers that rely on alternating magnetic flux induced by changing current, standard transformers cannot work with steady DC because constant direct current produces static magnetic fields and no electromagnetic induction. This fundamental difference makes the DC transformer adopt unique working principles for DC sensing and signal conversion.

Current Transformer Standards

Current transformers (CTs) are essential instrument transformers widely used in power systems for current measurement, energy metering, and relay protection. A complete set of standards defines their design, manufacturing, testing, accuracy classes, safety requirements and operating limits to guarantee consistent performance and interoperability across different manufacturers and regions.
