Electrical Power System Components

The electrical grid in North America is a combination of various elements that provide a means of taking electrical power from where it is produced to where it used. The electrical grid is defined as an interconnected network of power stations, transmission lines, and distribution stations that transmit electrical power …

Three-Phase Transformer: Working, Selection & Connections

three phase transformer

In this section, single-phase transformers are reviewed with additional information; however, the main focus of the coverage here is the three-phase transformer. Three-phase transformers are used in large utility-scale renewable energy systems. Single-Phase Transformer Basics Recall that transformers act as a passive component in which two or more magnetically coupled …

Three Phase Electric Power Explained

Three-Phase Voltage

Single-phase ac voltage is generated in some smaller renewable energy systems. Power companies almost universally generate three-phase (3φ) ac electric power, and they supply it to industries as three-phase or convert it to single-phase (1φ) for residential and small commercial operations. Larger industrial users use the three-phase ac directly for …

Electric Power System and Equipment – Voltage Ratings

Electrical power systems used in buildings may be divided into three voltage classes. The system voltage is defined as the voltage between lines, or line-to-line voltage. Extra-low-voltage systems (50 V and below) This class is normally used for control, signal, and communication systems. Low-voltage systems (nominally below 600 V) The practical range …

Operational Amplifier (Op Amp): Basics, Operation, Applications

operational amplifier

An operational amplifier (op-amp) is one of the most widely used integrated circuits (ICs). An operational amplifier (op-amp) is a high-gain, directly coupled amplifier that uses external feedback to control response characteristics. See Figure 1. Figure 1. Types of operational amplifiers (op amps) include dual-power and high-current, high-power op amps. …

DC Power Supply Filter Types

A filter is a circuit in a power supply section that smooths the pulsating DC to make it more consistent. A filter minimizes or removes ripple voltage from a rectified output by opposing changes in voltage and current. The filtering process is accomplished by connecting parallel capacitors and series resistors …

6 Most Common Power Quality Problems

The quality of incoming power to a load is important because all electrical and electronic equipment is rated for operation at a specific voltage. The rated voltage is actually a voltage range. Typically, this range is ±10%. However, with many newer components derated to save energy and operating cost, the …
