eSeminar Series on Surge Protection
The purpose of this series is to offer training to all parties interested in surge protection of power systems. This series is an extension of the live in-person training seminars offered by ArresterWorks for the past several years. Since it is not very prudent to produce an online seminar more than 1-2 hours in length, the previous one and two day seminars are broken down to lengths that are more reasonable and will be offered as a series of training sessions.Hardware requirements:
A high-speed network with a computer that has an audio output and a microphone. If your computer is not equipped with audio, a phone connectioin is available. Video camera on the computer is preferred for better two-way communications, but is not necessary.
Time requirements:
All eSeminars will be open 30 minutes prior to the start time to allow connection issues to be resolved. The presentation time can vary depending on questions, but should not extend past the end time by more than 20%. The session is interactive and questions will be addressed as they come up. There will also be time at the end for Q&A session.
Schedule:
eSeminars are scheduled on a request basis. If you would like one scheduled for you personally or for a group, contact ArresterWorks
Fees:
Fees for eSeminars are availalbe on request. All eSeminars must be paid for with credit cards prior to receiving login in instructions. The fee applies to each person attending the eSeminar. For larger groups, a sepcial eSeminar can be set up.
Continuing Education Credits:
If you are interested in CEUs a short exam can be downloaded and completed. Upon successful completion a credit can be issues (Florida PE Board Approved) from ArresterWorks. Feedback forms must be filled out to receive credit.
Customized and New eSeminars:
If you do not find the surge protection topic you need in this list, please contact Jonathan.Woodworth@ArresterWorks.com. It is quite possible, that a course could be easily designed and offered.
