Measurement devices in an electrical power system usually take the form of instrument transformers designed to represent high voltage and high current quantities as smaller, proportionate electrical signals. Controllers take the form of protective relays and other control systems designed to display and record the measured quantities, as well as take an automatic control action.

Thus, it is important to be able to measure and control electricity, not only for reasons of efficiency but also for sale, taxation, safety, equipment protection, and reliability of service. As with any other quantity we wish to measure and control, the systems designed for these purposes may be divided into three general categories: sensors to measure, final control elements to exert influence, and controllers to make the necessary control decisions automatically.

Power circuit components include power sources, Uninterrupted Power Supply (UPS) devices, relays, electrical transformers, and voltage/current converters. Industrial control panels do not contain controlled equipment or the main power supply. Because they do not house the controlled equipment or machines, ICPs can be seen as the modular control units of an automated system.

Power supplies tend to get a reputation as one of the most important power considerations of a DC control circuit - but we can’t ignore other key players: power filters, converters, and backup power modules.

Needless to say, modern electrical power grids are highly complex systems. The critically important nature of a functioning power grid is difficult to overstate for any first-world nation, as so much depends on the uninterrupted flow of power from generating stations to customers. The complexity of power grids and their control systems will only increase over time as more renewable generation capacity (e.g.

You can definitely get fine resolution with other systems, and it is very dependent on the controller and feedback mechanism. Even the most precise actuator is only as good as the control and the sensor. It’s not uncommon to get sub-micron resolution from electric actuators, particularly ...

To understand such systems, the output and other unknowns of the system must be evaluated upon different inputs. This process is the basis for system dynamics response. In this article, we will dive deeper into the mathematical relationships between the elements of mechanical and electrical control systems.

An interposing relay is an interface between a control system and a higher power circuit to provide isolation or amplification of mismatched voltage and current from a control to a load circuit. ... A reliable definition of a relay is ‘a combination of both monitoring and sensing devices.’ A relay is operated by a variation of conditions in one electrical circuit (the control) to affect the operation of electric devices in the same or another electrical circuit (the load).

As you can see, the strategy of using independent “relay” devices to command a large power circuit breaker to trip is a much more sophisticated way of ensuring power system protection and reliability than constructing each circuit breaker with its own internal overcurrent mechanism. This is truly an “instrumentation” approach to electric power control: intentionally locating the intelligence of the system to a set of dedicated control devices which may be upgraded and reconfigured on demand to meet continually changing needs.
