Step voltage signaling device

2017 International Conference on Industrial Engineering, Applications and Manufacturing (ICIEAM), 2017
There is a dangerous zone of step voltage in 6-35 kV power networks with an isolated neutral in the emergency mode caused by a ground fault about a point of damage. People and animals occurring in the step voltage area face a severe danger of electrical shock and even death.

Detecting and Avoiding Step Voltage Hazards

IEEE Transactions on Power Delivery, 2015
Uncontrolled flow of electrical current in the earth may have a range of effects, from barely perceptible to dangerous electrical shocks, or unintended electrical heating resulting in fires. This paper promotes awareness of hazards from ground-potential rise and briefly describes the root causes of voltage in the ground. It is proven that the values of

A Secondary-Side Phase-Shifted Bidirectional Soft-Switching DC–DC Converter Employing Step Voltage Switching for Eliminating Device Voltage Overshoot

IEEE transactions on power electronics, 2023
In this article, we present a modulation strategy for bidirectional power flow for the step voltage switched (SVS) secondary-side phase-shifted (SPS) dc–dc converter that eliminates the device voltage overshoot problem.

Flexible Step-Voltage Regulator for Unbalanced Distribution Networks

IEEE transactions on industry applications, 2022
This article presents a new device named flexible step-voltage regulator (FSVR) based on a multiwinding transformer for unbalanced distribution networks. While the traditional step-voltage regulator (SVR) can be used to control the voltage magnitude only,

Estimation of Parameters of Five-Phase Induction Motors Using Step Voltage At Standstill

IEEE transactions on energy conversion, 2021
This paper proposes a new method to estimate the electrical parameters of five-phase induction motors based on the response to a step voltage applied to the stator with the rotor at standstill.

Coupled Inductor-Based Single-Switch Quadratic High Step-Up DC–DC Converters With Reduced Voltage Stress on Switch

IEEE Journal of Emerging and Selected Topics in Industrial Electronics, 2023
In this article, two single-switch quadratic boost converters based on a three-winding coupled inductor (CI) are proposed. These converters provide a high voltage gain in a low duty cycle, reduced voltage stress on the power switch, continuous input ...
