Description
Field engineers in the telecoms industry may be expected to work on single and 3 phase AC fed DC power supply systems incorporating rectifiers, batteries and isolation/change over switches.
Through presentation, tuition and practical exercises this training course will provide the relevant knowledge to enable telecoms engineers to work safely using appropriate methods, procedures and equipment to inspect, test and maintain these systems.
This 1 day course will include theory and practical exercises on inspection and testing methods to ensure the systems remain safe for use. Training exercises are conducted using the latest DC Telecoms equipment and systems.
This course seeks to raise awareness of the statutory and non-statutory requirements for safe working on electrical systems and to demonstrate correct methods, tools and procedures to enable operatives to work safely on live electrical systems.
The course is delivered over a full day. The training will be delivered at our training centre in Tring, Herts where it is able to provide the relevant training facilities, equipment and materials.
What you will learn
Delegates will be able to recognise the key elements of a typical AC/DC telecoms power system and demonstrate the relevant procedures for safe inspection and testing of those systems.
Delegates will be able to understand and identify the risks associated with live-working on AC and DC systems and understand the correct procedures for managing those risks.
