Reconstruction of existing ripple control transmitters
Simultaneously with production of new transmitters, EPA carries out reconstruction of older transmitters, and in that occasion, generally in the case of HV transmitters fitted with the SMK 250kVA static converter, the replacement of the VLK 04 system for the new VLK 10 takes place.
In the case of 110kV transmitters also VLK 02 and VLK 03 systems are being replaced for the new VLK 10, during which time we offer two possibilities in terms of high power parts of the SMK: Either, in the case of newer SMKs (younger than 10 years) the modification of existing high power parts so as to be compatible with the new VLK 10 system, or the complete replacement of the existing high power parts for newly innovated SMK 1600 ripple control units. The transmitters on the higher level of quality are the result of these reconstructions, i.e. transmitters fulfilling certain requirements, especially those related to fully unmanned substation operation with the possibility of remote supervision and control.
This way the following ripple control transmitters were reconstructed in Czech Republic :
