Electric switching

What skills will you learn in the Electric switching?

After completing Electric switching, you will be able to find and correct faults using a structured approach by interpreting power circuit and control circuit diagrams. You will also learn how to take measurements.

After completing the course, you will have sufficient expertise in how electric motor controls operate.

As a follow-up to this course, we recommend that you complete the NEN 3140 Skilled Person training course. This will help you do your job safely.

Content of the Electric switching

Construction and operation of electrical controls
• Reading diagrams: Memory circuits, latching circuits, sequential circuits
• Using measuring equipment (multimeter, Duspol)
• Voltage, current and resistance in practice (Ohm's Law)
• When to use alternating current and direct current
• Normally open, normally closed and changeover contacts
• Series and parallel switching in contacts and consuming devices
• Knowledge of components (magnetic switches, auxiliary relays, timer relays)
• Timer relays: on and off delay, combined on and off delay

Construction and operation of motor controls
• Power supply construction, converter, single-phase and three-phase power supplies
• Short-circuiting and overload
• Circuit resistance and voltage loss (Ohm's Law)
• Single-phase and three-phase cage motor (three-phase motor)
• Interpreting motor data (type plate), connecting motors
• Motor circuit for immediate activation, reversing the direction of rotation
• Star-delta circuit for three-phase motors
• Testing motors (winding resistance and insulation resistance)
• Measuring current draw of motor using an ampere clamp meter
• Frequency converters and soft starters, their operation and basic configuration
• Motor circuit protection: Fuses, thermal protection, motor protection switch

Troubleshooting electrical controls
• Procedure using a step-by-step and strategic approach (FRIDS)
• Input - control - output, thinking in blocks
• Using PLCs in control systems
• Measuring methods: Expected value - Process value – Waterfall method - Testing efficiently
• Reading techniques for comprehensive diagrams: Reduce to subdiagrams
• Cross referencing of components and relays, potential referencing
• Through testing, finding the actual cause of faults in relays and PLC controls

Who will benefit from Electric switching?

Do you want to increase your knowledge of industrial electrical engineering as found in switch and control boxes? And do you want to learn how to troubleshoot? Then this is the course for you! You will be trained to Maintain level. This is comparable to mbo-3 [vocational training] work and education level.

Practical training centre for the course Electrical Circuits

During the practical part of the training the following is covered:

Relay switching
