What is a  Transformer?

Transformer Definition

A transformer is a passive device that transfers electrical energy from one circuit to another using electromagnetic induction.

Transformer Parts And Construction

  • Primary Winding of Transformer

  • Magnetic Core of Transformer

  • Secondary Winding of Transformer

Working Principle

The working principle of a transformer involves mutual induction between coils to transfer electrical energy.

Core Function

The core of a transformer provides a path with low reluctance, essential for efficient flux linkage between the windings.

Voltage Conversion

Depending on the turns ratio between the primary and secondary windings, a transformer can either step up or step down the voltage.

  • If the primary coil has more turns than the secondary coil, the voltage decreases, known as step down.

  • If the primary coil has fewer turns than the secondary coil, the voltage increases, known as step up.

Inrush Current Impact

The inrush current is the initial surge of electricity experienced when a transformer is switched on, affecting its immediate performance.

Analysis of Testing Methods for Turns Ratio and Connection Mode of Special Transformers
1 Error Analysis of Traditional Turn Ratio Testing MethodsThe QJ35 turn ratio bridge and other single-phase-phase-based testers all use the double-voltmeter principle. The QJ35, however, eliminates power supply fluctuation interference via bridge balance. For three-phase transformer ratio testing with a single power supply, corresponding terminals must be shorted and data converted, turning three-phase tests into independent single-phase measurements, with √3 Yd conversion based on connect

Cost Differences and Performance Comparison of 35kV New Energy Transformers Based on Dry-Type, Mineral Oil, and Vegetable Oil
Cost Differences and Performance Comparison of 35kV New Energy Transformers Based on Dry-Type, Mineral Oil, and Vegetable Oil
For users, when purchasing a 35kV new energy transformer, choosing between dry-type, mineral oil-filled, or vegetable oil-filled types involves multiple considerations. These include user habits, maintenance-free performance, safety and fire resistance, volume and weight, among others. However, cost differences are undoubtedly one of the most crucial factors.To illustrate the issue intuitively, this paper selects a three-level energy efficiency dual-winding new energy transformer with a rated ca
