Service Heroes

Rein­hausen not only builds on-load tap-chang­ers, but also offers an exten­sive ser­vice range for trans­form­ers. In the US, the ser­vice port­fo­lio is espe­cial­ly exten­sive.


From tap chang­er main­te­nance, through trans­former instal­la­tion, to the con­struc­tion of entire pri­ma­ry sub­sta­tions, Rein­hausen Man­u­fac­tur­ing offers cus­tomized ser­vice solu­tions for trans­former man­u­fac­tur­ers, ener­gy providers and indus­tri­al com­pa­nies in the US from its five loca­tions and with 65 ser­vice tech­ni­cians across the entire coun­try.

TAP CHANGER SERVICE

 

The hub for tra­di­tion­al tap chang­er ser­vice is the Rein­hausen OLTC pro­duc­tion loca­tion in Hum­boldt, Ten­nessee. From there, experts trav­el by any means nec­es­sary to work sites across the entire US, includ­ing remote regions like Hawaii and Alas­ka. All of the tools need­ed in the field are housed in a trav­el box mak­ing the twelve-per­son team fast and flex­i­ble.

TRANSPORT, INSTALLATION AND MAINTENANCE

 

The ser­vices span the entire life­cy­cle of the trans­former. Even the trans­porta­tion of trans­form­ers, includ­ing dis­as­sem­bly, removal and reassem­bly, can be done by our experts. The ser­vices also include main­te­nance, which may include but is not lim­it­ed to replace­ment of bush­ings, gas­kets, cool­ing fans, and oil treat­ment.

MODERNIZATION OF TRANSFORMERS

 

Mod­ern­iza­tion ser­vices include the instal­la­tion of advanced mon­i­tor­ing sys­tems, such as ETOS® automa­tion solu­tion for dig­i­tal­iza­tion. In addi­tion, ser­vices also include tra­di­tion­al retro­fits, such as the replace­ment of OLTCs, which often­times involves elab­o­rate and exten­sive mod­i­fi­ca­tions to the trans­former. Rein­hausen Man­u­fac­tur­ing has a vari­ety of tap chang­er prod­ucts and ser­vices in its port­fo­lio to fit our customer’s needs.

CONSTRUCTION OF PRIMARY SUBSTATIONS

 

In the states of Ari­zona and Neva­da, Rein­hausen Man­u­fac­tur­ing is plan­ning and build­ing turnkey pri­ma­ry sub­sta­tions in all volt­age ranges, from 69 to 500 kilo­volts. The ser­vice port­fo­lio spans from engi­neer­ing to final test­ing, and sup­port dur­ing com­mis­sion­ing activ­i­ties.


With unified forces

How the service team is set up in the US.

10 Oil rigs treat trans­former oil across the entire coun­try, from small trucks for tight spaces to semi trucks with all the equip­ment on board.

5 Num­ber of ser­vice bases in the US. All 50 states are served from these loca­tions.

1987 Rein­hausen Man­u­fac­tur­ing was found­ed in Hum­boldt, Ten­nessee.

65 Total num­ber of ser­vice tech­ni­cians employed by Rein­hausen Man­u­fac­tur­ing. They are dis­trib­uted across the coun­try, which allows them to be on site quick­ly.

24 Num­ber of ser­vice trucks in the fleet. They have mea­sur­ing tech­nol­o­gy and tools on board

DIALYSIS FOR TRANSFORMERS

One of the most impor­tant pieces of equip­ment for ser­vice work is the oil rig. For elab­o­rate trans­former work, all the oil — rang­ing from a few hun­dred to thou­sands of gal­lons — has to be drained and tem­porar­i­ly stored. Dur­ing the work, how­ev­er, mois­ture ingress may occur, which is detri­men­tal to the trans­former.

The oil rig plays a key role here: Using the pumps installed in the oil rig (1) , the oil is first pumped out into a ster­ile con­tain­ment and, after the work is com­plet­ed, it is pumped back into the trans­former. Before refill­ing, the vac­u­um and boost­er pumps (2) apply a fine vac­u­um to the entire tank (<1 mbar), which removes a major­i­ty of the mois­ture and also pre­vents the for­ma­tion of air bub­bles dur­ing fill­ing.

Once the oil is com­plete­ly filled back in the trans­former, the oil rig remains in oper­a­tion and cir­cu­lates the oil. In this process, with the oil con­stant­ly heat­ed to approx. 50° C (oil heat­ing 3 ), is where mois­ture extrac­tion (inlet/outlet fil­tra­tion 4 & 5) and degasi­fi­ca­tion (degassing cham­ber 6 ) occur. The water tak­en out of the sys­tem is col­lect­ed and con­tin­u­ous­ly mea­sured through dig­i­tal mois­ture mon­i­tor­ing. Depend­ing on how much mois­ture is in the sys­tem, this process can take from one day to sev­er­al weeks.
