Single-phase insulator transformers

IEEE Potentials, 2002
To show that voltage surges are effectively transmitted between the windings of insulator transformers, a relatively simple and functional test was prepared. The test applied differential-mode voltage surges with small amplitudes to the primary winding of three different types of single-phase no-load insulator transformers.

Estimation of residual flux in single phase transformer using dynamic modeling of two winding single phase transformer

2017 International Seminar on Intelligent Technology and Its Applications (ISITIA), 2017
This study deals with estimation of residual flux in 1 kVA 1-phase transformer. Transformers used in the study have two type core cutting topology. The transformers were modeled with MATLAB software and then simulated to obtained inrush current. Experiments were also done in order to obtain its inrush current with different demagnetization time.

Idling Mode Simulation of Single-Phase Transformer

2019 IEEE International Conference on Modern Electrical and Energy Systems (MEES), 2019
A unifying mathematical model of the single-phase transformer is developed. This model superposes the external electrical circuit and an electromagnetic fields model, which describing the processes of electromagnetic energy conversion in a transformer.

Single-Phase Power Transformer Formed Cores

Transactions of the American Institute of Electrical Engineers, 1950
For many years power and distribution transformer cores were built of hot-rolled laminations assembled into a core structure. When cold-rolled, oriented strip steel was introduced into transformers, new types of distribution transformer cores were developed.

Leakage flux in a single phase transformer

Journal of Magnetism and Magnetic Materials, 1984
Abstract The effects of aluminium magnetic shielding and mild steel magnetic shunts on the leakage flux in the steel tank of a single-phase 50 Hz low power transformer have been investigated.

Single-Phase Universal Active Filter Without Transformer

APEC 07 - Twenty-Second Annual IEEE Applied Power Electronics Conference and Exposition, 2007
This paper presents an universal active filter for harmonic and reactive power compensation in single-phase system. It is a combined system of a series active filter and a shunt active filter without use of transformer. The proposed system is suitable for applications where the size is a critical factor.

THD Reduction of Single-Phase to Single-Phase Step-Down Cycloconverter Using Multiwinding Transformer

2019 5th International Conference on Advances in Electrical Engineering (ICAEE), 2019
There is an increasing interest within the industrial community to apply single-phase cycloconverters in variable speed drives and variable frequency applications. For variable speed drive application of cycloconverter to improve the power quality i.e., the harmonic components of the converter’s output voltage should be low which are always measured in

Novel Zero-Sequence Blocking Transformer (ZSBT) Using Three Single-Phase Transformers

IEEE Transactions on Energy Conversion, 2013
Zero-sequence blocking transformers (ZSBTs), used to block the zero-sequence components that are present in a three-phase system, are commonly built winding the three phases around the same core limb. They are difficult to construct, especially in high-power applications that use large cross-sectional cables, as they require a symmetrical winding ...
