EE0200 : Practical Troubleshooting of Electrical Equipments & Control Circuits

 

This practical and highly-interactive course includes various practical sessions and exercises.  Theory learnt will be applied using our state-of-the art simulators. 

No matter how complete or expensive an electrical system is, the components of the system begin to deteriorate as soon as they are installed and failure of some component in the system will ultimately result.  If deterioration is not checked, it can cause electrical failures and malfunctions.  In addition, load changes or circuit alterations may be made without overall design coordination, which can result in improper selection of equipment, or settings of protective devices, or wrong trip units installed in the circuits.  There are certain definite and logical methods and procedures in locating the source of trouble on electrical equipment.  Experience indicates that in most cases where the exact trouble spot is not determined, it is because the troubleshooter has not applied his or her knowledge properly. 

 

Blown fuses, overload contacts, open contacts, short circuits, burned out coils, and grounds are responsible for most electrical circuit failures.  These problems should be relatively easy to find and correct.  Many of the more “sophisticated” systems fail because of some minor adjustment problem that requires more information than has been furnished to all the repair people. Records indicate that this type of failure is infrequent. 

 

The larger and more complicated system usually fails for the same reasons as the smaller and less complicated system: dirty contacts, open circuits, blown fuses, burned out coils, faulty grounds, broken limit arms, or some other mechanical aspect relating to the electrical operation.  

 

This course covers the troubleshooting of all types of apparatus and equipment found in the electrical power systems serving industrial and commercial facilities, large institutional complexes and office buildings, and utility type substations and generating plants.  The course provides practical information on the troubleshooting of electrical equipment and control circuits for the maintenance personnel who install and care for such equipment.  

 

The course utilizes a state-of-the-art Electrical Troubleshooting Simulator, where participants will actually troubleshoot electrical faults.  The software will allow participants to operate the circuit, take meter readings, remove wires, replace components and other troubleshooting activities.  Participants will actually solve multiple faults on a highly realistic circuit simulation of an electric motor consisting of numerous relays, switches, lights, solenoids, limit switches, reversing starter with overloads, push buttons, step down transformer, and safety switch.  Further, multimeters, clamp-on meters, ammeters, megohmmeters, proximity voltage meters, hand-held oscilloscopes and other meters will be thoroughly discussed as plant electrical troubleshooting tools.  This course concentrates on both safety and efficiency to achieve the ultimate goal of savings through the reduction of lost production time.
