In accordance with relay engineers’ desire NPP “Dynamica” improved RЕТ-VAH instrument transformer module. New device RЕТ-VAH-2000 in comparison with RЕТ-VAH module not only has increased power and increased output voltage up to 2000V, but is encapsulated in a new plastic enclosure which makes it more comfortable for use.
RЕТ-VAH-2000 module is intended for use with RЕТОМ-21 device and is capable to carry out tests within the following range:
Attention! – RЕТОМ-21 test system configuration is at the user option.
It is of future user option to include RЕТ-VAH or RЕТОМ-6000 modules into RЕТОМ-21 test system configuration. This choice is conditioned by the fact that РЕТОМ-6000 not only is capable to perform all RЕТ-VAH module functions but to test insulation strength. Moreover it operates off-line.
