Introduction

The direct current generator (DC) is an essential component in various electrical systems, converting mechanical energy into DC electrical energy. One of the methods to reinforce the DC generator is through the strengthening of the shunt, where the field resistance is installed parallel with anchor resistance. In this context, determining the critical resistance value in the shunt field is crucial to achieve the desired induction stress. This article aims to provide an in-depth analysis of the determination of critical resistance for voltage generation in guidance current generator strengthening shunt, with a focus on the application in the laboratory of FT-Asu Electric Energy Conversion.

Understanding the Direct Current Generator

A direct current generator is an electric engine that converts mechanical energy into DC electrical energy. The process involves the field currents flowing through the terrain winding producing magnetic flux, which then cuts the conductor in the anchor, producing an induction voltage. The shunt resistance determines the amount of field current, which ultimately affects the magnitude of the magnetic flux and induction voltage. The higher the value of the shunt field resistance, the smaller the field current and the magnetic flux produced.

Critical Resistance: The Key to Optimal Performance

Critical resistance is the maximum shunt field resistance value that allows the generator to generate induction stress. If the shunt field resistance value exceeds the critical value, the generator will not be able to produce an induction voltage, because the field current is not strong enough to produce adequate magnetic flux. Therefore, determining the critical resistance value is essential to achieve optimal performance in the direct current generator.

Critical Speed: The Minimum Rotation Speed Needed

Critical resistance value is also closely related to the critical speed of the generator. Critical speed is the minimum rotation speed needed by the generator to generate induction voltage with a certain shunt field resistance value. The greater the value of the shunt field resistance, the higher the critical speed needed. This relationship is crucial in understanding the optimal operating conditions of the direct current generator.

This research was conducted at the Electrical Energy Conversion Laboratory, Department of Electrical Engineering, Faculty of Engineering, University of North Sumatra.
