The 25kV single-phase PT is equipped with over-current and over-voltage protection. The current limit output is 200VA, the rated secondary output is 15-30VA, the accuracy is not less than 0.5, and the working voltage is 3000/100V.The use of high-quality materials and advanced manufacturing process ensures the long life and reliability of the voltage transformer.
Basic Principle: Single-phase voltage transformers work according to the principle of electromagnetic induction. They contain windings around an iron core, through which the incoming high-voltage signal can be stepped down to a measurable low-voltage signal. This conversion process allows the voltage signal to be efficiently transmitted to other equipment for processing and analysis.
Uses: One of the main uses of single-phase voltage transformers is power metering. In domestic and industrial power distribution, meters often use variable transformer to measure the amount of power consumed so that accurate electricity bills can be issued. In addition, they are used to monitor the status of the power system so that faults can be detected in time and the necessary measures taken to ensure the constant voltage and reliability of the grid.
