Power Transformer Protection System Using Differential Relays in PT PLN (Persero) PLTGU of the Belawan Generation Sector

Introduction

In the world of electricity, the transmission channel is vulnerable to lightning strikes, which can cause a very dangerous phenomenon known as overvoltage. This overvoltage can exceed the existing isolation limit, leading to a short circuit disorder. The short circuit disorder can be divided into five categories, including a short-circuit disorder of one phase to the ground, two phases to the ground, three phases to the ground, as well as interference between two or three phases. Among these various types of disorders, the most common is one phase disruption to the ground, which is often caused by lightning strikes.

The Importance of Power Transformer Protection System

To overcome the risk of this short circuit disorder, the use of effective protection systems is very important. One method commonly used is differential relays. This relay serves to detect a difference in current between the two sides of the transformer. When a disturbance occurs, this current difference will increase, so that relay can quickly respond and disconnect to prevent further damage to the equipment.

The Role of Differential Relays in Power Transformer Protection System

In the context of PT PLN (Persero) PLTGU of the Belawan generation sector, the application of a protection system with differential relays is very crucial. Power transformer, which serves to increase or reduce voltage, has a central role in electricity distribution. If the transformer is interrupted, the impact can be very broad, ranging from physical damage to the equipment to disruption in electricity supply.

Applying the right protection system, such as differential relays, not only provides protection against equipment but also increases the reliability and continuity of electricity supply. This relay can accurately detect interference currents and respond to the Mailing Mileton. The use of modern technology such as digital current sensors can also increase the accuracy of detection and accelerate system responses.
