QUALITROL-IRIS POWER IS THE WORLD’S LARGEST PROVIDER OF MONITORING AND TESTING EQUIPMENT FOR MOTOR AND GENERATOR WINDINGS PDTech Dielectric Response Analyzer (DRA-3) for Off-Line Insulation Diagnosis of Generator and Motor Windings The dielectric response analyzer is used for off-line insulation diagnosis for generators and motors and is also applicable to transformers. It measures the charging and discharging currents (also called polarization and depolarization currents or PDC) of the winding of stator or rotor insulation. The resulting measurement provides information on the condition of machine insulation, such as, cleanliness, ageing, resin decomposition and resin cure. The PDTech DRA-3 System allows you to connect all three phases and the ground at one time. The phases are measured sequentially step by step, without any interaction from test personnel. The measurement steps are automatically controlled and stored by a computer connected to the instrument. The PDTech DRA-3 System also allows the possibility to measure all three phases together to ground, each phase separately and between the phases. Once data is stored, it can be analyzed by the evaluation program in order to get a complete report of the measurement including standard parameters such as insulation resistance, polarization index, etc. IRIS POWER OFF-LINE PRODUCTS PDTech Dielectric Response Analyzer (DRA-3) Hardware Specifications Input Voltage Universal 90 to 240 VAC Voltage Supply for Notebook Same as input voltage (galvanically insulated) Warning Light Connector for warning light, indicating a high voltage is present High Voltage Integrated floated DC high voltage source, up to 10 kV, preset voltages 0.5, 1, 2.4, 5 and 10 kV, 1 mA High Voltage Control Integrated 10 kV Reed relay controlled with Digital I/O PC card Shunt for Current Measurement 1 MΩ Current Measurement Range 1 mA to 0.1 nA, resolution 1 pA SOFTWARE Specifications Data Acquisition Fully automatic for measurement: separate phase to ground, all phases together, and between phase analysis Evaluation Automatic calculation of parameters as polarization index, insulation resistance, absorption index, etc Comparison Included software for comparison of up to 4 different measurements Data Report Automatic export to Microsoft Excel 2000 and above Installation KIT CONTents ORDER • DRA3 instrument • 1 Black Alligator Clip • Transit Case • A 5 m USB Cable • Power Cable • Operating Manual • 4 HV Cables • Software kit CD HVDRA: DRA‐3 Dielectric Response Analyser, charging/ discharging current measurement, up to 10 kV • 3 Red Alligator Clips QUALITROL-IRIS POWER HAS BEEN THE WORLD LEADER IN MOTOR AND GENERATOR WINDING DIAGNOSTICS SINCE 1990, PROVIDING A FULL LINE OF ON-LINE AND OFF-LINE TOOLS, AS WELL AS COMMISSIONING AND CONSULTING SERVICES.
