- Basic systems - Inspect, test, and operate various ac and dc control and protection wiring, schemes, and components as found in electrical apparatus and assemblies. Evaluate scheme and results.
- Basics of Control Components Control, as it relates to machines and processes, is a broad term that means anything from a simple toggle switch to a complex system.
- Wiring Diagram Book Examples of Control Circuits
- Motor control - Inspect, test, and operate motor control systems specific to reduced voltage starting, variable frequency, variable voltage, dc drive, wound rotor, synchronous, and other motor applications.
- Fundamentals of Motor Control Basic principles and language of AC motor control.
- Basics of DC Drives Although AC motors and vector-control drives now offer alternatives to DC, there are many applications where DC drives offer advantages in operator friendliness, reliability, cost effectiveness, and performance.
- Field Inspection and Testing of Medium-Voltage Motor Control Centers Equipment Installation Checks and Testing Requirements for MV MCCs.
- Medium-Voltage Motor Starters and Protection This article will concentrate on mechanical and electrical interlocks that all ANSI compliant medium-voltage motor starting equipment must have as well as motor protection that includes thermal algorithms, number-of-starts limitation, negative sequence protection, resistance temperature detectors (RTDs), and more.
- What To Check When Commissioning Variable Speed Drives Once all the basic checks have been completed and the commissioning test sheet completed, the VSD is ready for energization.
- Medium-Voltage Motor Starters and Protection Medium-voltage (2.3 kV to 15 kV) starters have been around for many years and we have very complex ways of controlling and protecting the circuits and the motors.
- Knowledge of PLCs, networking, and automated control systems.
- Basics of PLCs A programmable logic controller (PLC), also referred to as a programmable controller, is the name given to a type of computer commonly used in commercial and industrial control applications.
- RS-485 basics: Introduction Since its definition in 1983, RS-485 has become the preferred interface standard for many industrial fieldbus applications.
- RS232: Basics, Implementation & Specification RS-232 is a standard communication protocol for linking computer and its peripheral devices to allow serial data exchange. In simple terms RS232 defines the voltage for the path used for data exchange between the devices.
- What's The Difference Between The RS-232 And RS-485 Serial Interfaces? In general, the RS-232 is best for short-distance low-speed requirements. The RS-485 is for higher speeds over longer ranges or if duplex networking capability is required.
- Ethernet Tutorial – Part I: Networking Basics This tutorial will explain the basics of some of the most popular technologies used in computer networking.
