IEEE Transactions on Power Electronics, 2022 This article presents a novel modulation scheme for device voltage stress mitigation and comprehensive analysis of the impact of transformer leakage inductance in a current-source solid-state transformer (SST). Different from dual active bridge (DAB) SST, the operation of the current-source SST is similar to that of a flyback converter.

The Calibration of Current Transformers by Means of Mutual Inductances [PDF]
Transactions of the American Institute of Electrical Engineers, 1915 Reasons are given for the selection of mutual inductances as a means for calibrating current transformers, the most important of which is the wide use to which they may be put besides the calibration of current transformers. The design and manufacture of the apparatus are described, reasons being given for the choice of the form of the secondary coil ...

Impact of inductive current transformers on synchrophasor measurement in presence of modulations
Measurement, 2020 Abstract Instrument Transformers (ITs) are essential devices for all the measurement tasks, f.i. metering, protection and diagnostics, in electricity grids, since they scale voltage and current down to levels compatible with measuring instruments. At the input of Power Quality (PQ) instruments and Phasor Measurement Units (PMUs), inductive voltage ...

A New Modular XRAM-Like Inductive High- Current Pulse Generator Circuit Topology
IEEE Access, 2020 XRAM (MARX spelt back words) is currently a very important circuit for high current pulse generators. In our previous studies, an XRAM-like circuit was proposed based on multiple pulse transformer modules and a capacitor connected in parallel.

Method for Internal Fault Testing of Instrument Transformers With Sectioned Active Parts
IEEE Access, 2021 Relevant international instrument transformer standards specify internal arc testing to prove the transformer behavior under internal fault conditions. However, the test is defined in a way that does not recognize that it is possible to limit and reduce ...
