WHAT IS A REGULATOR AND HOW DOES IT WORK?

The regulator, which is often used in electrical appliances, is the elements included in most devices. Regulators prevent systems from being damaged because of more efficient use of electronic devices and voltage imbalances that may occur. The most common questions about these devices that come up in most places are “What is a regulator?” and “How does the regulator work?" there are questions. In this article, we will answer these two questions.

WHAT IS A REGULATOR?

A regulator is the name given to devices that provide voltage regulation in situations of imbalance, such as when energy is supplied in low-voltage systems. The regulator regulating the imbalances in the mains voltage prevents the efficiency from falling.

The regulator keeps the physical quantities such as frequency, power, speed, pressure, voltage and current constant at a certain level. In addition, the regulators prevent any damage that may occur by electromechanically disconnecting the output voltage during drops and rises in voltages other than the setting by means of an electronic protection system. Due to this feature, the use of regulators is resorted to in networks such as computers, fax machines, laboratory devices, homes, and lighting systems.

Regulators without overvoltage protection are not recommended for use at overvoltage. The most used systems of regulators are those located in rural areas where transformer distances are very far, as well as in unorganized industrial areas that use the same transformer as factories.

HOW DOES THE REGULATOR WORK?

The regulator usually works by connecting in series to transformers or precision-built variable auto-transformer systems. These devices, acting as boosters, adjust the voltage compensation. The regulator consists mainly of a finder element, a servo motor, and has complex and simple types. In a short circuit that occurs on the load side, the regulators ensure that the large currents that occur go away.

Unfortunately, simple type regulators cannot respond instantly to the changes we have just mentioned, complex type regulators should be used if a regulator is sought that will respond instantly to an irregularity that may occur. These regulators, known as shunt sensing series regulators, respond instantly to even small changes.

The elements protecting the regulator are separate from the regulator. These elements often come into play when the regulator is unable to do work and stop the system or machine. In regulators, the alternating current from the mains is transferred first to the transformer and then to the variable autotransformer by an electronic servo circuit. The motor and the ends of the motor connected to the variable autotransformer are connected to the servo circuit, while the servo circuit is connected to a transformer where it receives power.

HOW TO CONNECT THE REGULATOR?

In 1-phase static regulators, the input-output connection of the device should be made by following the diagram given on the device. With one phase to be taken from the electrical panel, the neutral cable is connected to the terminal assembly on the back panel of the device.

the connection of 3-phase static regulators is also made by following the diagram given on the device in a similar way to 1-phase static regulators. The neutral wire is taken from the device's electrical panel with 3 phases and connected to the terminal group on the back panel sequentially as L1-L2-L3 and N from the left, then the neutral and phase connection of the load to be fed is made respectively.
