Switching Transients Analysis Fundamentals
Switching Transients Analysis Fundamentals Author: Velimir Lackovic Switching transients severe enough to cause problems in industrial power systems are most often associated with inadequate or malfunctioning breakers or switches and the switching of capacitor banks and other frequently switched loads. The arc furnace system is most frequently studied because of its high frequency of switching…
Shunt Capacitor Bank Design and Protection Basics
Shunt Capacitor Bank Design and Protection Basics Author: Velimir Lackovic Shunt capacitor units are typically used to deliver capacitive reactive compensation or power factor correction. The use of shunt capacitor units has gained popularity because they are relatively inexpensive, simple to install and commission and can be placed anywhere in the electrical distribution system. Their…
PV Systems Safety
PV Systems Safety Author: Velimir Lackovic This course is intended to be a reference with helpful and easily-accessible instructions on how to work safely with photovoltaic (PV) systems. It includes description of specific hazards, their frequent causes, and strategies to prevent and avoid them. This course has three different sections: PV System Characteristics and Hazards:…
Principles of HVDC Transmission
Principles of HVDC Transmission Author: Velimir Lackovic Designers must decide between AC and DC transmission. This course addresses this challenge by exploring line losses and their relationship to the rating and size of chosen conductors. This course is suitable for engineers with a desire to understand the basic principles of HVDC transmission. It reviews the…
Practical Power Cable Ampacity Analysis
Practical Power Cable Ampacity Analysis Author: Velimir Lackovic Cable ampacity studies calculate the current-carrying capacity (ampacity) of power cables in underground or above ground installations. This ampacity is determined by the maximum allowable conductor temperature. In turn, this temperature is dependent on the losses in the cable, both I2R and dielectric, and thermal coupling between…
Power Quality Measurements – Essential Theory
Power Quality Measurements – Essential Theory Author: Velimir Lackovic The decline in quality of power is a big issue due to an increase in the use of inverters in power electronics, an increase of unbalanced loads from large furnaces or rectifiers, and complex power distribution associated with power network interconnections for new energy plants. Poor…
