Ask Dr. UPS for advice on any situation
concerning your facility.
We have just recently learned that we must comply with OSHA and NFPA
70E requirements regarding Arc Flash hazards. What does that mean and
where do we go to get help? Debi
You come to Doctor UPS and I will help you understand what needs to be
done to protect those under your care and responsibility. Arc Flash is an
explosive release of energy due to either a phase to ground or phase to
phase fault. OSHA, NEC and the NFP have determined that improper work
procedures, inadvertent contact with the electrical system and collateral
build up of corrosion or DUST can trigger the arc. A study of your system
will determine the risk of personnel injury with exposure (short circuit
analysis) to this type incident, recommendations to reduce energy levels,
labeling of the hazards, training for staff and a list of personal protective
wear necessary while working in each area of risk. This IS NOT an
inexpensive assignment. You must keep in mind that implementing a
comprehensive Safety Plan saves you the expense and productivity loss
that is associated with a downed electrical system.
Dr. UPS we have a small manufacturing firm and occasionally our
computers freeze up on us and we must re-boot two or three times a day.
It happens even more in the summer. Please advise what we can do to
correct? Is it the computer or our power? Thanks, Tom
Sorry you are having this problem. It might be your computer but more
likely is harmonic transients within your electrical system that are
affecting your computer. A surge suppressor or a double conversion UPS
that conditions your power will solve this issue. If you can afford to protect
your entire office with a unit that would protect all your circuits would be
an even better fix. You need to know the voltage going in and from the
UPS, the amount of amperage you wish to protect and if there are
receptacles on the back of the UPS for additional items requiring
protection, such as your printer and monitor, etc. 500VA should be enough
for a stand alone computer set-up. If you are doing the whole office we
would come off the circuit by the panel and protect the volume of
equipment served by one or more circuits. We would need to calculate the
amperage required depending on the load. Decide how much time you
want for battery back up and if you want automatic shutdown software for
when you are away. It would notify you by page or email that the system
had gone on battery. Think about a maintenance contract unless you are
one of the few that regularly change the batteries in your smoke detector.
You'll need to add the UPS to your to do list.
Dear Dr. UPS
Why do you say I need to have a UPS to protect my home office equipment?
Sandy
Good question Sandy, you go to the head of the class! Losing your
electrical power isn't the only bad thing that can happen to delicate
electronic devices. And by the way, your home office is filled with
electronics as well as your family room, bedroom and kitchen. (TVs,
monitors, stereos, printers, faxes, phones, copy machines, etc, etc). You
can have voltage sags and surges, brown outs (a series of under voltages)
spikes in voltage, lightning strikes during storms and noise (ringing
disturbances from the utility) to name a few. A UPS prevents 100% of the
above mentioned disturbances. Other products like power conditioners,
voltage regulators and k-rated transformers will correct from 80-99.5% of
the above situations. It depends on how stable you view your supply of
power from your utility is to your facility. If you NEVER have a blackout,
then you don't need batteries, just clean continuous power available with a
power conditioner, voltage regulator or k-rated transformer. Call me to
discuss.
