    thicker These transformers are designed so that all layers of the insulation can pass the thickness and high potential voltage tests required If one insulation layer breaks the next layer will be able to provide the required safety Transformer standards Various national and international safety agencies have published standards relevant to the design construction and testing of transformers A partial list of those standards follows Standards published by the International Electrotechnical Commission IEC include IEC 60076 Power transformers IEC 60905 Loading guide for dry type power transformerst IEC 61000 Electromagnetic compatibility EMC IEC 61558 Safety of transformers reactors power supply units Standards published by Underwriters Laboratories UL UL 5085 Standard for Low Voltage UL 5085 UL 544 Medical and dental equipment Canadian Standards Association CSA C22 2 NO 66 1 06 Low voltage transformers There exist a number of regional national and local deviations from the abovelisted standards For example in the U S the city of Los Angeles requires the use of tamperproof thermal protection and nonflammable materials in transformers due the region s high seismic activity Three phase transformers A transformer for use with 3 phase power is constructed by winding three single phase transformers on a single core Delta and Wye connections In a three phase transformer there is a three legged iron core as shown below Each leg has a respective primary and secondary winding Figure 2 A 3 phase transformer core As can be seen the three phase transformer actually has 6 windings or coils 3 primary and 3 secondary In power applications these windings are usually connected in one of two configurations Delta or Wye In a Delta connection there are three phases and no Neutral An output Delta connection can supply a three phase load In a Wye connection there are three phases and a Neutral An output Wye connection enables the transformer to supply a threephase voltage say 3 400 Vac and also a voltage for single phase loads namely the voltage between any phase and Neutral in this example 230 Vac The Neutral point can also be grounded to provide greater safety When circumstances permit most industry professionals prefer to use the Delta input Wye output connection for connecting a 3 phase transformer connection in power distribution applications If the transformer secondary supplies large amounts of unbalanced loads the delta primary winding provides a better current balance for the primary source The Delta Wye connection is used to create a common output neutral when no such neutral exists in the line This type of connection also supresses noise from the line to the secondary Figure 3 Three primary windings in Delta and three secondary windings in Wye GAMATRONIC S ISOLATION TRANSFORMERS Features Gamatronic offers a wide selection of 3 phase isolation transformers Standard models are available in a range from 6 to 150 kVA larger and smaller units are available on request On customer request Gamatronic can suppy transformers capable of accepting a range of input voltages and supplying any one

  • Mega V2 UPS
    these systems highly acclaimed for today This article attempts to shed light on these issues from commercial and technical aspects The History of Modular UPS The modular UPS did not spring out of thin air it was enabled by technological advancements The three phase UPS which was prevalent in the 90 s was mainly based on 6 or 12 pulse rectifiers with thyristors PWM inverters with IGBT components fast high performance power transistors and output transformers necessary for the inverter technology The rectifier included big chokes for the purpose of improving performance These chokes and transformers outlined the measure and weight of the systems The transformer less technology and shift to rectifiers with PFC technology allowed the systems to be dramatically smaller The use of advanced technology assisted in the creation of a three phase UPS with the output power of 10 000 VA that weighed 9 Kg only Compare this UPS to the previous one s that weighed over 100 Kg this was a remarkable advancement Several UPS manufacturers throughout the world realized the potential and immediately began to implement the new technologies They did not rest with upgrading the existing systems but rather opted for further advancement building a brand new modular system Resistance to modularity One can understand customer s initial hesitation towards modular technology raised from the fears of transformer less technology For years UPS systems were based on inverter with transformer suddenly consumers were told that the new system which comprised of transformer less inverter would work even better than before Today this might sound odd but at the time most electrical consultants would testify that the system was better with a transformer Among other things they claimed that the advantages of a transformer based UPS are that the load output current is completely separated from the utility power input current by a method known as galvanic isolation It also completely eliminates all direct current to the load which can be harmful to it Benefits of the Modular UPS Manufacturers invested a lot of effort to show case the positive aspects of the product These include Reliability Reliability is one of the most crucial demands from the UPS Even clients who want to save money and are prepared to settle for a third grade system will still search for the promise of as high a MTBF as they can find What is reliability when it comes to the UPS Continuous provision of power to the load the objective is to keep the system running on inverter even in case of a fault without transferring to bypass like it would in a common system Size and Weight As far as weight and size are concerned there is a big advantage to a system without transformers and power chokes The smaller and lighter the system the cheaper the shipment and storage are Furthermore if the client is interested in a redundant UPS a modular system with one extra module will be at least twice as small as
