1. Chloride Australia Welcomes Stowe Australia To A Power Protection Seminar

2. Today’s presenters: Carlo Quiriconi Technical Services Manager Graham Higginson Area Manager Qld

3. Power Protection & Business Continuity
A Power Protection system is a critical tool in minimizing Business Continuity risk -
Manages power quality
Provides support in the event of power interruption
Reduces the risk of disruption to critical business processes
Reduces the risk of lost productivity
Reduces the risk of economic loss
Reduces the risk of disruption to customer service & loss of business

4. Growing Need for Power Protection
UPS power is typically used to support IT infrastructure -
Computer Rooms; Data Centres; Trading Floors; Call Centres; General Office
Other Applications include –
Industrial Control Systems; Security Systems
Two major issues are driving use of UPS -

5. Growing Need For Power Protection
Degradation Of Power Quality
Lack of investment in power infrastructure by power utility companies.
Reduction in electrical network maintenance to reduce cost. This decreases the reliability of the power network
Onus onto the end user to provide performance requirements to suit their needs.

6. Growing Need For Power Protection
Increasing Demand For Quality Power By The End User
The use of microprocessor based equipment in day to day office business activities requires the continuous availability of quality power to avoid damage to critical equipment.
The use of microprocessor based equipment in manufacturing processes requires protection from outages to avoid unplanned & uncontrolled downtime.

7. Advantages of UPS Power
Protection Against Power Interruption
The primary function of the UPS is to protect the downstream equipment from power fluctuations -
Sags or dips in voltage
Total absence of incoming voltage which can last milliseconds or minutes.

11. UPS Performance Terminology
Rectifier
Rectifiers performance is typically qualified as 6 or 12 pulse. This determines the type of current reflected into the mains supply. A 12 pulse produces less “harmonic” or non linear current into the mains supply.
PWM IGBT Inverter
PWM stands for “Pulse Width Modulation”. This is the “State of the Art” inverter switching technology used to recreate the AC waveform from the DC supply.
The power module used in the inverter bridge is called an Insulate Gate Bipolar Transistor (IGBT).
Battery Design Life (Sealed Lead Acid)
The battery quality is determined by the “Battery Design Life”. Lower rated UPS systems (< 10kVA) use 5 year design life batteries.
Larger UPS systems typically use 10 year design life batteries and in some cases up to 15 years design life.

17. True On Line UPS (Double Conversion)
Advantages
Continuous Regulation Of Output Voltage & Frequency
The load is supplied with conditioned power at all times.
Higher Reliability
UPS internal components are in continuous operation. The internal components are not in stand by operation to support the critical load.
Disadvantages
Efficiency
There is a cost of ownership due to heat losses

19. Interactive Technology (Stand By Mode)
Advantages
Efficiency
Improved efficiency due to direct supply from mains
Disadvantages
Non-Regulated Output Supply
Direct mains supply exposes critical load to voltage & frequency variations
Lower Reliability
Internal components are rated for short term operation during power absences

20. UPS Configurations Single UPS Parallel UPS Parallel Redundant (N+1)
Independent Dual UPS (N+N)

21. Single UPS (Single Input Supply)
Typically for Lower rating UPS < 10kVA in single or three phase

22. Single UPS (Dual Input Supply)
Typically for higher rating UPS > 10kVA three phase

23. Parallel UPS (2 units up)
Load requires all UPS available for supply capacity
All UPS can be considered as one UPS system

24. Parallel Redundant (N+1) (2 units up)
Configuration allows for one UPS at a time to be isolated without removal of UPS supply.
The maximum load permissible on the UPS system is determined by capacity remaining with the removal of a single UPS unit

25. Independent Dual UPS (N+N)
Dual plane installations. (Dual Cord Technology)
Higher reliability required and achieved due to duplication of all infrastructure to end equipment.

26. External Maintenance Bypass Introduction
Purpose
Facilitates transfer of output load UPS to an alternative supply source for UPS maintenance works or UPS replacement. Ensures no “LIVE” power is present on the UPS (OH&S).
Key Features
Make before break changeover facility
Interlock facility with UPS to inhibit transferring between two sources which are not synchronized.
Changeover switch can have 1-4 poles.

27. External Maintenance Bypass Introduction
Interlocking Systems
Rotary Switches -
Electro-mechanical via a solenoid or blocking relay which inhibits the rotation of the switch. A push button enables the switch to rotate and simultaneously transfers the UPS to static bypass
Mechanical Interlock which inhibits the rotation of the switch. A push button enables the switch to rotate and simultaneously transfers the UPS to static bypass during the transfer operation.
Circuit Breakers/ Switches -
Mechanical inter-lock via two Fortress/Castell keys located in UPS output switchboard and a third key connected into UPS system transfer control. The changeover circuit breakers cannot be closed without the keys present.

28. External Maintenance Bypass Configurations
Rotary Wrap Around (3 Position)
Rotary Changeover (2 position)
Keyed Changeover

29. Rotary Wrap Around External Bypass Switch
Typically installed for single or three phase UPS up to 10kVA
ADVANTAGES
- Single supply required
DISADVANTAGES
3 pole more expensive than 2 pole
Bypass and UPS share one supply

30. Rotary Changeover External Bypass Switch
Typically installed for 3 phase UPS systems from 10kVA to 160kVA
ADVANTAGES
- Less expensive than a 3 position
- Independent supply sources for UPS and Bypass
DISADVANTAGES
- Requires second supply source from switchboard

31. Recommended Design Two Position Rotary Switch
Special feature - Safety interlock with maintenance bypass supply

32. Sample of a Two Position Switch

33. Keyed Change Over Bypass Switch
Typical Installation
Utilized for large UPS systems with rating typically >160kVA
Reasons
It is more cost effective to use circuit breaker or isolators >250A.
Higher fault current rating
External maintenance bypass is incorporated into UPS Input/Output Switchboards.

34. Keyed Change Over Bypass Switch
UPS “A” key when removed forcing UPS into Static Bypass
“A” key inserted into “External Maintenance Bypass Switch “to allow it to close and trap key”
“UPS Output Switch” opened releasing an “A” key to return to UPS system..
