Developed a voltage sensor with precision class 0.5, amplitude better of 0.5 %, and phase better of 20’ or 0.33º

Integrated Rogowski sensors for acquiring phases and neutral currents in the electronics of automation, and protection, obtaining a precision of the set lower than 0.5 % or primary 30 mA for sensitive neutral and 0.5 % or 50 mA in phases

Asset management


Quality analysis functionality (harmonics, THD, gaps and surges) has been developed.Also, has been developed a function for detection of intermittent faults in subestation relay. This function detect faults that are extinguished by themselves in a few milliseconds, and that over time will lead to a frank fault.

Developed a new compact version of the monitoring system located in the secondary substation. This system implements communication features based on Web Services with offices, by adding Modbus protocol for integration with devices that collect BT and MT measurements
