The power frequency induction voltage divider is a device composed of three interconnected current transformers. By switching the device's output voltage to a specific ratio of the input voltage, it ensures precise voltage proportionality, stability, and universal applicability. Additionally, this equipment features high input impedance and low output impedance, providing critical performance for accurate electrical measurements. It is widely used in various measurement circuits and devices.
This device employs a two-stage transformer design with the highest accuracy, overcoming the drawbacks of parallel multi-disk induction voltage dividers where the rear disk significantly affects the front disk's load, as well as the disadvantages of series configurations that introduce isolation errors and low input impedance. The schematic diagram of the two-stage transformer multi-disk induction voltage divider is shown on the following page. As illustrated, the multi-disk induction voltage divider consists of multiple two-stage transformers connected in parallel. A 1/10 section of the primary winding is connected to the secondary winding's terminals via a double-pole switch, forcing the secondary disk to operate at 1/10 of the primary disk's voltage. Due to the excitation winding, the secondary disk's impact on the primary disk's circuit is minimal, while isolation errors are eliminated, resulting in high accuracy.
