BASIC ELECTRICAL KNOWLEDGE FOR LOW VOLTAGE APPLICATION

INTRODUCTION FOR BASIC ELECTRICAL KNOWLEDGE FOR LOW VOLTAGE APPLICATION

The International Electro-technical Commission (IEC) defines supply system low voltage as voltage in the range 50 to 1000 V AC or 120 to 1500 V DC.
In electrical power systems low voltage most commonly refers to the mains voltages as used by domestic and light industrial and commercial consumers. “Low voltage” in this context still presents a risk of electric shock, but only a minor risk of electric arcs through the air.
Since, most of the electrical devices using “Low Voltage” in our technology system, the organization shall assign Technician / Line Leader / Supervisor to monitor the application of “Low Voltage” in our electrical system.

To ensure effectiveness of “Low Voltage application” in manufacturing Industry especially to maximize production output and minimize machine breakdown delay time, the Supervisor / Line Leader / Technician must have basic knowledge of electrical engineering to monitor the operation of electrical system.

Basic Electrical knowledge for Low Voltage Application will expose the participants on:

• Basic principle of electrical system
• Low voltage distribution system
• Low Voltage supply specification
• Electrical Devices and basic function
