RMT 9922 is a device designed to control automatically and with an unplugged equipment the features of HVB and HVA three-phase transformers.
This control includes, among other things, the verification of tap transformer. With a connection to the primary and secondary of the transformer and to the tap transformer command, the functioning is entirely automatised and generates directly a complete report referencing the different parameters.
