Optimize asset management with HVEX online monitoring

Power transformers are among the most important assets in the transmission and distribution networks of electrical energy. Failures in transformers are usually catastrophic and cause irreversible internal damage, as they often occur in the insulation systems of coils and bushings. The Online PD Monitor provides accurate information about the integrity of the insulation to maintenance and asset management teams, capable of measuring online partial discharges of high-voltage windings, capacitance, and dissipation factor (tan δ) of the condenser bushings of power transformers.
