The present technical work describes the update and implementation of measurement equipment to carry out high voltage tests at industrial frequency. The proposed update allows for the replacement of an analog measurement device with a digital one (DMI 551). This updating is based on the usual needs of High Voltage Laboratories, as regards the requirement of counting with an appropriate measurement system to obtain reliable values so as to determine the correct criteria in the results of high voltage tests in alternate current at industrial frequency. In this work, the main characteristics of the updated measurement system are exposed. Besides, it is described the design, calculation, and construction of a low voltage new stage of the voltage divider which forms part of the measurement system. On the other hand, the results of the electric tests carried out in the implementation contrasted with the complete system together with the respective conclusions are exposed and analyzed. Finally, the tests carried out on the proposed measurement system made it possible to highlight the improvements of the modified system with respect to the original system. In particular, the contrast tests revealed a very good response to the modified system.
