ınp - electrical equipment
Introduction
Technical staff operating, inspecting or maintaining the electrical equipment of installations in an international industrial environment should to know in depth and perfectly different aspects such as: Selection and erection of a wiring system besides the identification of conductors from different countries and the usual inspection and test plan for cables; the schema of the reasons of each typical and most common inspection and test plan and their details; the purpose of the tests, standards and procedures, the knowledge about the typical acceptance criteria, mistakes, instruments and equipment needed, etc.
This training is not intended to cover or address the requirements and acceptance criteria of every country because these could surely vary. It is intended to ensure that the fundamental principles and practices are understood and in line with IEC requirements.
Who should attend?
- Mechanical & electrical engineers.
- Electrical equipment inspectors.
- Technical staff working in production area.
- Technical staff working in maintenance area.
Objectives
This course has the following objectives:
- Having a clear idea on the different types of cables, their construction and terminology.
- Being able to use electrical formulas and understanding American Wire Gauge as well as its current ratings and conductor resistance.
- Studying how the generators and motors work and their main standards.
- Knowing the different types of generators and motors understanding their advantages and disadvantages in order to decide e which one is better for any particular requirement.
