Why VRDTs are becoming ever more important<\/h2>\n
\n
\n

<\/i><\/i>1 DECENTRALIZED GENERATION<\/a><\/h3>\n
\n

is increas\u00ading, and with it the need to increase the per\u00adfor\u00admance of dis\u00adtri\u00adb\u00adu\u00adtion grids.<\/p>\n<\/div>\n<\/div>\n

\n

<\/i><\/i>2 ADDITIONAL LOADS<\/a><\/h3>\n
\n

Mobil\u00adi\u00adty and heat will be elec\u00adtric in the future. The host\u00ading capac\u00adi\u00adty for these addi\u00adtion\u00adal loads must increase.<\/p>\n<\/div>\n<\/div>\n

\n

<\/i><\/i>3 DUAL ROLE<\/a><\/h3>\n
\n

With solar sys\u00adtems on roofs, more and more con\u00adsumers are also becom\u00ading pro\u00adduc\u00aders. Dis\u00adtri\u00adb\u00adu\u00adtion grids have to dynam\u00adi\u00adcal\u00adly respond to these dynam\u00adics.<\/p>\n<\/div>\n<\/div>\n

\n

<\/i><\/i>4 MORE FLEXIBILITY<\/a><\/h3>\n
\n

in sec\u00adtor cou\u00adpling can be uti\u00adlized more effi\u00adcient\u00adly of dis\u00adtri\u00adb\u00adu\u00adtion grids have greater capac\u00adi\u00adty.<\/p>\n<\/div>\n<\/div>\n

\n

<\/i><\/i>5 THE COMPLEXITY OF GRIDS IS INCREASING<\/a><\/h3>\n
\n

and the dig\u00adi\u00adtal\u00adiza\u00adtion of dis\u00adtri\u00adb\u00adu\u00adtion grids helps mas\u00adter this issue.<\/p>\n<\/div>\n<\/div>\n<\/div>\n\n

Simply powerful<\/h2>\n
\n

The third generation of ECOTAP\u00ae VPD\u00ae makes voltage regulation the standard in distribution transformers.<\/h3>\n

<\/p><\/blockquote>\n

500,000 SWITCHING<\/big><\/strong>
\nis what ECOTAP\u00ae VPD\u00ae is capa\u00adble of. This exceeds the aver\u00adage ser\u00advice life time of a typ\u00adi\u00adcal local grid trans\u00adformer.<\/p><\/blockquote>\n

Smart\u00adly into the future<\/big><\/strong>
\nThanks to ECOTAP\u00ae VPD\u00ae, dig\u00adi\u00adtal con\u00adnec\u00adtion is no prob\u00adlem and the VRDT becomes active equip\u00adment in the dig\u00adi\u00adtal dis\u00adtri\u00adb\u00adu\u00adtion grid.<\/p><\/blockquote>\n

Very com\u00adpact<\/big><\/strong>
\nThe vol\u00adume of the new ECOTAP\u00ae VPD\u00ae has been reduced by 50 per\u00adcent in com\u00adpar\u00adi\u00adson to its pre\u00adde\u00adces\u00adsor.<\/p><\/blockquote>\n

30 %<\/big><\/strong>
\nless weight is what the new ECOTAP\u00ae VPD\u00ae includ\u00ading motor-dri\u00adve unit brings.<\/p><\/blockquote>\n

Main\u00adte\u00adnance-free oper\u00ada\u00adtion<\/big><\/strong>
\nVac\u00adu\u00adum tap-change tech\u00adnol\u00ado\u00adgy ensures a long ser\u00advice life and vir\u00adtu\u00adal\u00adly no main\u00adte\u00adnance effort.<\/p><\/blockquote>\n

Auto\u00admat\u00aded pro\u00adduc\u00adtion<\/big><\/strong>
\nThe new ECOTAP\u00ae VPD\u00ae was designed for auto\u00admat\u00aded pro\u00adduc\u00adtion in high quan\u00adti\u00adties. As a result, costs can be reduced sig\u00adnif\u00adi\u00adcant\u00adly and volt\u00adage reg\u00adu\u00adla\u00adtion can become the stan\u00addard in dis\u00adtri\u00adb\u00adu\u00adtion grids. Pro\u00adduc\u00adtion takes place in a new\u00adly con\u00adstruct\u00aded plant in Italy.<\/p><\/blockquote>\n

How does a VRDT work?<\/h2>\n

<\/p>\n

New pow\u00ader sup\u00adpli\u00aders, such as pho\u00adto\u00advolta\u00adic sys\u00adtems on roofs, lead to volt\u00adage increas\u00ades in local net\u00adworks. New loads, such as those caused by e\u2011mobility, lead to addi\u00adtion\u00adal volt\u00adage drops. Dis\u00adtri\u00adb\u00adu\u00adtion grids to date have not been designed for this. Since medi\u00adum-volt\u00adage and low-volt\u00adage grids are rigid\u00adly cou\u00adpled via dis\u00adtri\u00adb\u00adu\u00adtion trans\u00adform\u00aders, the most com\u00admon option used in the past, was to expand the grid. That is expen\u00adsive! Depend\u00ading on grid con\u00addi\u00adtions, the host\u00ading capac\u00adi\u00adty for addi\u00adtion\u00adal loads and sup\u00adpli\u00aders can be increased two to four times using a VRDT, with\u00adout need\u00ading to rein\u00adforce the cable net\u00adwork. How does this work? The con\u00adtrol and reg\u00adu\u00adlat\u00ading unit 1<\/span> con\u00adtin\u00adu\u00adous\u00adly mea\u00adsures the sec\u00adondary volt\u00adage 2<\/span> uand auto\u00admat\u00adi\u00adcal\u00adly out\u00adputs a sig\u00adnal to the tap chang\u00ader when it needs to change the trans\u00adformer ratio 3<\/span>. The con\u00adtrol and reg\u00adu\u00adlat\u00ading unit can also be con\u00adnect\u00aded with SCADA sys\u00adtems 4<\/span> to sup\u00adport more sophis\u00adti\u00adcat\u00aded volt\u00adage con\u00adtrol schemes.<\/p>\n

\n

Where does the ECOTAP\u00ae VPD\u00ae fit in?<\/h2>\n

In addition to distribution grids, VRDTs are also suitable for industrial applications and renewable production systems.<\/h3>\n

 <\/p>\n

Distribution grid<\/h3>\n

The dis\u00adtri\u00adb\u00adu\u00adtion grid is the main appli\u00adca\u00adtion for the new ECOTAP\u00ae VPD\u00ae with 30 amperes.It keeps the volt\u00adage in the low volt\u00adage grid sta\u00adble and is designed for trans\u00adform\u00aders up to a volt\u00adage class of 24 kV.<\/p>\n

 <\/p>\n

Industry<\/h3>\n

If very pre\u00adcise volt\u00adage or a larg\u00ader reg\u00adu\u00adlat\u00ading range is need\u00aded, ECOTAP\u00ae VPD\u00ae with 100 amperes and change-over selec\u00adtor is the right choice. It offers 17 oper\u00adat\u00ading posi\u00adtions and sup\u00adplies indus\u00adtri\u00adal, agri\u00adcul\u00adtur\u00adal or com\u00admer\u00adcial process\u00ades with a defined, sta\u00adble volt\u00adage range, pro\u00adtect\u00aded against out\u00adside influ\u00adences.<\/p>\n

 <\/p>\n

Renewables<\/h3>\n

At high\u00ader pow\u00ader lev\u00adels but with less space, such as in wind pow\u00ader sys\u00adtems, ECOTAP\u00ae VPD\u00ae with 100 amperes and 9 oper\u00adat\u00ading posi\u00adtions is the right on-load tap-chang\u00ader. It can be eas\u00adi\u00adly inte\u00adgrat\u00aded into exist\u00ading trans\u00adformer design and helps opti\u00admize<\/p>\n
