Overview

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, overcurrent protection and switchgear.

Through presentation and demonstration, this training course provides an overview of DC Telecoms installations, installation methods and equipment .

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.

We also offer the option to deliver the course via webinar.

Who should attend?

This course is intended for managers, engineers and technicians who require an awareness of the requirements for the installation, inspection and maintenance of DC telecoms equipment. Those that require training in the practical aspects of the installation and maintenance of these systems should consider the TEL003 course.

Learning Outcomes

Delegates will be able to recognise the key elements of a typical AC/DC telecoms power system and understand 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.

The course is modular and includes the following:

  • Electrical Circuit Principles.
    • Current Flow.
    • Voltage Sources.
    • Resistance.
    • Ohm’s Law and Electrical Circuits.
    • Electrical Power.
