Power ProblemsA UPS performs two primary functions:
Protects connected loads from the effects of mains electricity power failures by providing an instant source of back-
up power in the event of a mains failure.
Filters and conditions mains power to protect connected loads from the effects of mains-born and system-introduced
power problems associated with electricity networks.
The following table gives an overview of the most common power problems, symptoms and their causes.
Problem
Power Blackout
Power Sags & Brownouts
Power Surge
Undervoltage
Overvoltage
Power spikes
Power Transients
/Switching
Line Noise
Frequency Variations
Harmonic Distortion
Symptoms
As the name suggests, a complete blackout and
failure of the power system for over 2 cycles,
which can result in system crashes, data loss
and/or corruption and hardware damage
Short duration undervoltages (75-86% below
what they should be), which last for a short
duration but can cause equipment to
malfunction or shut down and lead to data
and memory loss, data and equipment errors
and flickering lights.
This is where the voltage rises above normal for
short periods and can result in data and memory
loss, equipment malfunction or breakdown.
An undervoltage is similar to a power sag except
that it lasts for longer in duration and can cause
equipment to lock up, break down and lead to
data loss and/or corruption.
This is a sudden, rapid rise in voltage, the
duration of which lasts for a while and can have
devastating results such as data loss, equipment
breakdown, burned out circuit boards and a
total or partial electronic system failure.
A power spike is the same as an overvoltage
except much higher in voltage rise (up to
6000 volts).
These are rapid voltage peaks of up to
20,000 volts lasting a duration of 10-100
microseconds. Even though they last for less
than a second, it is enough to lead to equipment
damage, breakdown, data loss and component
stress, which can lead to future breakdown.
If not filtered out, line noise can cause system
and keyboard lock ups, data loss and errors
and data storage losses
This is a change in frequency from the normal
(50/60Hz). It can cause hardware to crash,
data corruption and loss, keyboards to lock
and software program failure.
Distortion of the normal sinewave waveform,
which can cause hardware damage, equipment
to overheat and communication errors.
Cause
• Utility or mains power failure.
• Tripping of downstream circuit breakers.
• Failure of the power distribution network.
• Large motor loads starting up.
• Heavy equipment starting up.
• Internal or mains power switching.
This can be caused by large motor loads or heavy
equipment being switched off.
The most usual cause of this is heavy demand
for utility power.
• Lightning strikes.
• Supply faults.
• Lightning strikes.
• Supply faults.
• Heavy equipment being switched on causing
high in-rush current.
• Utilities correcting line problems.
• Arcing faults and static discharge.
Electric motors, motor controls, relays, broadcast
transmission, microwave transmission and electrical
storms, which can result in Radio Frequency
Interference (RFI) and Electromagnetic Interference (EMI).
Power sources that are unstable, including generators.
Switch-mode power supplies and variable speed drives. Any
equipment that introduces a non-linear load transmission into
the system (i.e., printers, copiers, faxes and even some UPS).
Modular UPSModular UPS is a relatively new
phenomenon that allows for better
‘right-sizing’ of UPS systems. Several
leading manufacturers such as EATON
and Riello UPS now offer modular UPS
systems. Historically, UPS has had to
be oversized in order to build in
redundancy (using parallel
configurations) and to allow for future
system expansion, and this has
resulted in each unit within the system
running inefficiently. The call for
efficiency, particularly within the data
centre community, is loud and clear
and so modular UPS now enables UPS
systems to be right-sized and to run
efficiently while capacity and increased
redundancy can be introduced
incrementally. Small units of 12-15kVA
(depending upon UPS brand) can be
stacked or slid together using a
drawer-style approach within a
standard data centre rack. Each 12 or
15kVA unit is an independent UPS in
its own right with all of the associated
internal workings to enable it to
operate independently if required.
However, several units (6-8 per rack)
can be run together to provide
increased capacity and redundancy.
Some modular designs enable multiple
racks of units to be paralleled together
for further capacity. Modular UPS
carries a higher capital outlay but
because it enables more accurate
right-sizing is gaining ground in
applications (such as data centres)
in which progressive growth is
anticipated but impossible to predict.

The Different Types of UPSUPS are classed as either static or rotary. Within the static UPS category,
there are three types: online, line interactive and offline.
Online UPS (also known as VFI – Voltage and Frequency Independent)
This type of UPS continuously powers the load through its inverter, creating
a break-free supply in the event of a mains failure. It employs double-
conversion technology to convert the voltage twice, from mains ac to dc,
using its rectifier, and from rectifier dc to ac using its inverter), which
enables voltage and frequency levels to be tightly regulated. This type of UPS
continuously conditions power to ensure loads receive a clean, problem-free
supply. Newer designs of online UPS offer several operating modes in order to
improve economy and reliability. This type of UPS typically ranges in size from
single 700VA units to 800kVA modules, the larger of which can be employed
in parallel configurations to build in redundancy.
Line Interactive UPS (also known as VI – Voltage Independent)
This type of UPS is a step up from online designs and offers enhanced power
protection and additional line conditioning. When mains power is present, UPS
output is supplied via a built in Automatic Voltage Stabiliser (AVS), which
operates within a set input voltage window. An EMI/RFI filter is employed to
protect the AVS and load by clamping peak voltages to acceptable levels.
When mains power supply fails, the inverter is powered up and a relay
connects the load to the inverter output. Line Interactive UPS have internal
battery sets that provide a short duration runtime at full load. Runtime can
be extended with the connection of external battery extension packs.
Offline UPS (also known as VFD – Voltage and Frequency Dependent)
This type of UPS offers basic power protection, some line conditioning and
filtering and is used primarily for small, essential loads (such as work stations,
terminals, PCs) below 1kVA. When mains power is present, UPS output is
supplied via a built in EMI/RFI filter that provides limited protection from
spikes and transients. A simple charging circuit charges the internal battery.
The inverter is usually in offline or standby mode. When mains power fails,
the inverter powers up and a relay connects the load to inverter output. The
internal battery within and offline UPS offers 5-7 minutes of back up power
and there is no facility for adding runtime extension. This gives enough time,
however, in the event of a mains failure, to gracefully shutdown equipment
and spare it from damage.
Line Interactive and Offline UPS do not provide a break-free supply like Online
UPS does and this makes them unsuitable for some types of sensitive load.
Rotary and Flywheel UPS
Rotary UPS and flywheel UPS are mechanical devices that convert kinetic
energy into electrical energy using a rotating transformer, induction coupling
or a flywheel engine. They usually start at 500kVA in size and can range in
excess of 2MVA. Coupled with the fact that they typically carry a high capital
outlay cost, they are designed primarily for very large installations. The
advantages of these technologies are that they generate little in the way of
harmonics, offer a very high meantime between failure (MTBF), have better
fault clearing capabilities and can cope with leading power factor loads, such
as high-end Blade servers of the type used in data centres. In the right
setting, and for the right application, they also offer greater operating
efficiency, higher reliability and lower lifetime costs compared to equivalent
static UPS designs.
UPS ApplicationsThe UPS market has opened up in the past few decades and continues to
do so as more and more businesses and operations rely on electrical
equipment for their very continuity. If you think about it, everything we use
at work these days needs to be plugged in somewhere – even if it’s just to
recharge a battery.
The good news is that this opens up a whole raft of opportunities for us and
our trade partners and we are all geared up to help you make the most of it.
In any situation where a power loss or poor power quality will result in
business disruption, data loss or corruption or a breach in safety, some form
of power protection and alternative power source is required. The most
common form is UPS power protection alongside an onsite diesel generator,
both of which can be paralleled (two or more UPS and generators operating
together making up and parallel configuration power protection system) to
offer extended runtime and redundancy.
Below are outlined some common applications for UPS power protection:
ComputersMany businesses rely on computer systems today. Some, such as data
centres, sell hosting to customers and have to ensure specific levels of
uptime and availability. This category of application also includes file
servers, telecoms and communications equipment such as network servers,
switches, routers, PBXs and so on.
Financial SystemsSuch as those that run and operate retail EPoS (Electronic Point of Sale)
terminals and ATM (Automatic Teller Machines).
IndustrialEquipment that runs industrial processes, pumping equipment and so forth,
plus medical machinery and life support systems.
Security/Entry SystemsDoor entry systems (access control) are often controlled electronically and if
the power goes off they will either open (thus creating a potential security
breach) or stay locked (thus creating a safety issue for the people within).
Other systems that fall into this category are CCTV, automatic gates and car
park barriers.
Safety Emergency lighting, lifts, public address systems.
Remote applicationsRail signalling equipment, remote telecoms equipment, unmanned safety
and communications systems, broadcasting equipment and monitoring
systems.
