FIELD: test equipment.
SUBSTANCE: device has several units for conducting signal preliminary processing connected in parallel to final data processing unit through communication line. Device also has signaling unit. Final data processing unit has operator's PC and data collecting unit made on the base of industrial computer. Preliminary data processing unit has units for connecting object to measuring terminals of phases, commutation unit, a alarm protection unit and measuring unit. The latter has analog signal preliminary processing unit provided with primary converters on the base of precision resistors, analog signal basic processing unit, digitization unit and communication interface. Device performs continuous centralized inspection of capacitor-type paper-oil equipment (high-voltage terminals, current transformers) to detect leakage in insulators at early stage without switching equipment off.
EFFECT: improved reliability of operation.
