Electric switching (ROVC)

Introductie

Learn all about electrical engineering on the ROVC Electrical Circuits course! Learn to understand and troubleshoot switching technology.

Omschrijving

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! In this course you will learn, among other things, how to build and test various relay circuits from the ROVC tool case, and how to measure insulation resistance in three-phase motors.

Afronding

Electric switching final assessment

The course concludes with a digital exam. At the end of the course, you can choose the location, date, and time of your exam. However, the exam must be taken within 6 weeks of the last course session. After the exam, you will receive notification of your final result as soon as possible. Should you obtain a successful result, you will receive an accredited certificate.

CerTech

The organisation of our ROVC exams is done in collaboration with CerTech. CerTech is an independent exam board, responsible for the development, organisation, and administering of exams and tests. More than 10,000 candidates are examined each year on behalf of trade associations, consultancy firms and training institutes. This includes in particular technical, safety, security and organisational & communication exams.
