Based on an average 25-year transformer lifespan, a 1000kVA Wilson e2 transformer achieves typically £85,000 worth of energy cost savings during its service through loss savings alone.See page 4 POTENTIAL SAVINGS THROUGH VOLTAGE OPTIMISATION The Wilson e2 transformer will be manufactured to suit your site’s requirements and designed to deliver your desired output voltage. In addition the e2 comes with an extended tapping range at no extra cost allowing for further adjustments of output voltage when needed. Where supply voltage ?uctuates or a stable output voltage is required the Wilson e2+ comes with automatic voltage regulators to provide stabilised output voltage.See page 6YOUR SITE OUR OFFER YOUR SOLUTION1 2 344ENERGY EFFICIENCY AT OUR COREKVAStandard CRGO transformerSuper low loss AMDT Copper windingsSuper low loss AMDT AL windingsCore losses NLLLoad losses LLCombinedlossesCore losses NLLLoad losses LLCombined lossesCore losses NLLLoad losses LLCombinedlosses315 600 5350 5950 160 3850 4010 160 3650 3810500 900 7400 8300 250 5000 5250 250 4700 4950800 1150 11000 12150 325 7300 7625 325 6200 65251000 1350 12500 13850 500 7700 8200 500 6530 70301250 1575 16000 17575 565 10700 11265 565 10200 107651500 1700 21000 22700 630 14000 14630 630 13400 140301600 1800 21700 23500 700 15000 15700 700 14000 147002000 2300 24000 26300 800 19000 19800 800 18000 188002500 800 23000 23800800 24000 248003000 28000 31000Figures correct at date of ?rst publication, Nov 2012.UTILITYCIRCUIT BREAKERHV METERINGTotal powerpaid for onmonthly billYOURTRANSFORMERYOUR LV PANELTRANSFORMERLOSSESLOAD 1 LOAD 3LOAD 2WHY DO TRANSFORMER LOSSES MATTER?Did you know that your monthly electricity bill includes your transformer losses?COMPARE TRANSFORMER LOSSESSince its launch the Wilson e2 has been continually developed to improve energy ef?ciency and is the transformer product with lowest combined transformer losses available in the UK.3% of all energy generated worldwide is wasted through transformer losses. Around 4.6 million distribution transformers are currently installed in the EU. Their losses exceed 38TWh/year – this is more than the entire amount of electricity consumed by Denmark and equates to 30 million tonnes of CO2.he Wilson e2 transformer reduces these unnecessary lossesand helps organisations save operating costs and reduce CO2emissions.55WHAT ARE AMORPHOUS CORE TRANSFORMERS (AMT’S)?The cores of conventional transformers consist of stacks of laminations that are madefrom silicon steel with an almost uniform crystalline structure (CRGO). In transformers with amorphous cores, a ribbon of steel is wound forming the core.CUTTING TRANSFORMER LOSSES BY HALFTwo types of energy losses are inherent in the running of distribution transformers:WHAT ARE AMORPHOUS METALS?CRGO CRYSTALLINE CORE e2 AMORPHOUS CORE1 2Core losses are continually present from the day the unit is energised, that is 24h a day, 365 days of the year.Wilson e2 transformers combine amorphous metal cores with low current density conductors to reduce core losses by up to 75% and combined transformer losses by up to 50%.
