Course Description:
This extensive 2-day "Live" Instructor-Led (On-Site or Virtual) course is designed for Central Office Technicians or others with the responsibility for the installation, maintenance, troubleshooting, and repair of Central Office power equipment. NEW material has been added to reflect some of the latest tools available, including automatic power monitoring, infrared cameras, battery testers, plus sodium nickelchloride batteries.
The course provides a broad but detailed study of Central Office power systems, for both earlier and modern equipment. The course can also offer material on Data Center power, which typically uses AC-powered servers that are increasingly being used by telcos and service providers.
Basic electrical theory is effectively combined with a practical hands-on approach that enhances the students' learning experience. Examples include DC wattage versus reactive volt-amps, and how this affects surge currents and AC ground loops. Use of various testing equipment is demonstrated, showing how different vendors offer similar features. Multiple types of measurements are shown, including the use of DC current meters, battery resistance meters, ground field resistance meters, and automatic measurements made using continuously-monitored battery and power systems, showing on-demand measurements and trends.
Examples are shown for a typical central office with both earlier DC rectifier, battery, and BDFB components, plus newer systems that integrate some or all of these components. A remote equipment cabinet example is also shown, showing options for site grounding, including grounding that is coordinated with the power company.
The course can be adjusted to suit the needs of a given group, including grounding of outside-plant copper and fiber optic cables, and grounding at the customer premise, like shields, messenger leads, and tracer leads, plus sizing of the conductors and minimum length of the ground bar. Grounding to other metallic structures like fences, towers and nearby plant can also be included.
