VETZ medium voltage diesel gen-sets of the unit power from 1250kVA to 20000kVA

VETZ designs and manufactures medium voltage 6000V - 24000V gen-sets of the prime power from 1250kVA to 20000kVA with high-speed 1500rpm and medium speed 750-1000rpm diesel engines.

VETZ medium-voltage gen-sets are the customized power generating equipment manufactured with the special design and technology.

Base frames of VETZ medium voltage gen-sets consist of steel components processed with high accuracy for assembling on them heavy diesel engines of the weight more than 10tn (figure 1) and heavy medium voltage alternators, including two bearings machines, for the coupling with the engines as directly as with flexible adaptors (figure 2).

VETZ medium voltage diesel gen-sets are driven by engines of MTU (Germany) (figure 3), MAN (Germany), Perkins (UK) (figure 4), ABC (Belgia) and licensed engines. They are best on the market considering the power/weight/size/reliability ratio and application of high-tech electronic control units. VETZ applies the engines under OEM approval of their manufacturers to ensure the warranty. In VETZ powerful medium voltage gen-sets the engines are served with all necessary auxiliary devices such as cooling liquid heaters, fuel and oil processors etc (figure 5).

Control panels of VETS powerful medium voltage gen-sets enjoy the controllers tested on testing benches of engines manufactured to be used with their engines. The most important part of the tests is to ensure the smooth data exhange between the engines electronic governors and the control panels controllers to enable them to master the gen-set for most complicated tasks such as syncronozation with other gen-sets and with grid, and for the perfect protection of engines (figure 14).
