![]() ![]() HV and LV Bushing monitoring functions (option) Analog inputs can be free allocated to any additional sensor.Bottom and top oil temperature, ambient temperature (via additional temperature sensors).via voltage and current transformers/transducer.The main monitoring options are listed below: Voltages and Currents The Hydrocal 1009 can be used as a complete monitoring system for the condition of the transformer. Optional HV and LV bushing sensors for HV and LV bushing monitoring applications via communication interface.Optional IEC 61850 modem for SCADA connection.Optional DNP3 serial modem for SCADA connection.Optional 2G/3G modem with external adhesive antenna.Communication interfaces ETHERNET 10/100 Mbit/s (copper-wired / RJ 45 or fibre-optical / SC Duplex) and RS 485 to support MODBUS ®RTU/ASCII, MODBUS ÒTCP, DNP3 proprietary communication and IEC 61850 protocols.Advanced software (on the unit and via PC).Installation on the operational transformer without any operational interruption.Individual measurement of Hydrogen (H 2), Carbon Monoxide (CO), Carbon Dioxide (CO 2), Methane (CH 4), Acetylene (C 2H 2), Ethylene (C 2H 4), Ethane (C 2H 6) and Oxygen (O 2).controlling a transformer cooling system): It also has digital outputs for transmitting alerts or performing control functions (e.g. The device can serve as a compact transformer monitoring system by the integration/connection of other sensors present on a transformer via its optional analog inputs: Oxygen (O 2) can be a sign of excessive ageing or leakages within the sealing of hermetic transformers. It additionally measures Moisture in Oil (H 2O).Īs Hydrogen (H 2) is involved in nearly every fault of the insulation system of power transformers and Carbon Monoxide (CO) is a sign of involvement of the cellulosic / paper insulation, the presence and increase of Acetylene (C 2H 2) and Ethylene (C 2H 4) further classifies the nature of a fault as overheating, partial discharge or high energy arcing. It individually measures the key gases dissolved in transformer oil, such as: The HYDROCAL 1009 is a permanently installed multi-gas-in-oil analysis system with transformer monitoring functions. Measurement of CT (ratio, polarity, ohmic resistance, knee point).Measurement of Dielectric Frequency Response (DFR).Measurement of frequency response analysis (FRA).insulation resistance between each winding, core, clamps, shield Determination of capacitances windings-bushings and measuring dissipation factor.Measurement Voltage ratio and Phase displacement.Power Resistors for Industry, Energy & Traction.High Voltage Tests, Measurements & Adjustments.On-site Measurement & Commissioning Service.Testing the Tripping Time of Contacts and Moving Parts.Tests & Measurements on Switches & Disconnectors. ![]()
