Duration

This course is approximately 3 weeks in duration.

Learning Method:

The PDDP program is more of a self-guided learning style.
You are required to read the notes and materials given, complete the follow-up assignments on your own, send in your questions prior to your 1 hour webinar meeting (if required) and be involved in live discussion via the internet.
Once you have completed the course, you will receive a certificate of completion

Description

The UPS & Battery Systems are used in all applications that need reliable backup power, therefore it is very important to properly size; select; install and maintain this system

All life safety Systems require Black start capability therefore the most common use is an UPS which can provide clean high quality energy for as long as necessary.

Objective

The Students will learn the typical configuration of the UPS Systems; main parameters; Calculation and sizing for a specific application

Also most important tools to troubleshoot and maintain a UPS & Battery System, pending on type of UPS and battery Cells in use.

Target Audience

Electrical Engineers
Control Technicians
Technical Managers

After completion of the course the delegate will be able to

Understand the functionality of different UPS Type
Size the UPS and battery bank for an application
Recommend solution for a practical implementation
Perform Maintenance and Parameter settings on a UPS
Perform Battery maintenance and results interpretation
Design a complete UPS System and recommend the proper grounding solution

The PDDP Distance Education program works as follows:

Once you register for this course, you will be sent a login username and password for our online distance website.

You will receive the course notes in hard copy through the online website, you will receive a set of notes each week covering the course material.
A one hour video-conference session will be conducted by your instructor each week (if required). The objective of this session is to assist in solving the assignments, as well as answer student questions that should be sent to instructor early enough prior to the meeting time. In addition with being able to communicate with the instructor, you will also be able to communicate with other students in the same class and watch their questions being answered as well. (A high speed internet connection is strongly recommended for this feature).
Each set of exercises can be completed and submitted by the indicated date and your completed exercise will be marked online and and returned by your instructor.
To gain the most from your course, it is highly recommended that you participate fully in all discussions and exercises. Please remember that each course has a form of quiz or exercise at the end to test your understanding of the material. You will be informed of these dates when you receive the course schedule.

*Course commencement date is subject to instructor availability.
