New energy-efficient autotransformers (AT), as well as transverse control transformers (TPR) produced by CJSC "ZTR" will be installed at 750 kV substations "Zaporozhskaya" and "Dneprovskaya".
In new AO, no-load losses are 24% lower than in conventional AO, short-circuit losses on the low voltage side are 70% lower, on the medium voltage side - by 24%. Also, new JSCs are equipped with diagnostic systems, which will later be connected to the automated process control system (APCS) of the substation, which will allow the Customer to receive data on the state of the JSC online.
Especially for Ukrenergo substations, ZTR has proposed a new energy-efficient model of an autotransformer in the 750 kV voltage class, and now the manufacture of this equipment is being completed, which was recently inspected by Ukrenergo specialists.
Technical factory tests will begin at the end of October, which will also be attended by Ukrenergo specialists and representatives of FICHTNER (Germany), an international consultant from the creditor bank.
In particular, the compliance of the data obtained as a result of the tests of transformer equipment with the technical characteristics specified in the contract will be checked and confirmed. The first delivery of the AT-3 and TPR phases to the 750 kV Zaporozhskaya SS is planned at the end of this year.
REFERENCE: Zaporozhtransformator CJSC is one of the world's largest manufacturers of transformer equipment with experience in deliveries to 88 countries. The enterprise manufactures power oil transformers, electric reactors, controlled shunt reactors.
