Content

  • Introduction
  • UPS Products
  • Static Transfer Switches
  • GE’s unique technologies
slide3

Energy is the Key

The actual power grid was built to supply the 3 main inventions of the last Century:

the light bulb

the electric motor

the refrigerator

Utilities provide a reliability of 99,9%= 8 hours out of tolerance/year„good enough“ for this type of application

To produce, store, transfer and restore 4 MB of data

we „burn“ the energy equivalent of 1 Kilo of coal

Static Transfer Switches
  • STS Static Transfer Switch
  • Electronic switch that ensures uninterruptible switching between a preferred source and an alternate source. (primary or secondary)
  • Automatic operation – in case the preferred source is out of limits (fails) the load is automatically transferred to the healthy alternate source.
  • This transfer is seamless in case both sources are synchronized
slide11

Static Transfer Switches

  • Redundant power supplies
  • Redundant cooling
  • Over voltage protection
  • Front access for service
  • Manual bypass
  • Alarm contact interface
  • User friendly control panel
  • Neutral dimensioned for 200%
  • Unique conductivity detection

GE‘s unique technologies

RPA Redundant Parallel Architecture

High reliability UPS cluster with no single point of failure

SEM Super ECO Mode

Saving energy whilst maintaining high protection level

IEM Intelligent Energy Management

Award winning concept for energy savings

slide13

Redundant Parallel Architecture

utility supply

  • Up to 8 units in parallel
  • Any UPS able to be the logic leader
  • Decentralized bypass
  • Redundant Communication Bus
  • Transparent failover and recovery process
  • True redundancy with no single point of failure

VFI concept

2 Conversion Processes:

+ optimal protection for

mission critical applications

- increased energy losses

Balance:

For less critical loads run UPS on bypass continuously

In case mains is out of limits transfer the load to inverter

Super ECO Mode: not only is the load supplied on bypass, but the inverter is also switched off, increasing energy savings

Fast Transfer to Inverter

  • Super ECO mode
  • Efficiency : 98%
  • to Inverter in case Bypass is out of limits
  • Fast error detection
  • Extremely short transfer times (<2 ms)
  • User definable scheduling
  • Available for 10 – 500 kVA

Intelligent Energy Management

UPS: Cost of Ownership
  • Purchasing Cost & Installation Cost
  • Direct Operating Cost

Efficiency = Energy Losses = Heat

  • Indirect Operating Cost

Heat = air conditioning / Ventilation

  • Maintenance Cost
