高压电绝缘材料的数字测试-YH510

High Voltage Insulation Digital Tester-YH510 MAIN FUNCTIONS Measurement of Insulation Resistance and Leak Current Test Voltage: DC250V 5.00kV, Test Insulation Resistance 0 –5TΩ; Max Test Current 1mA Able to display insulation resistance, leak current, PI, DAR, and measurement time. Stepped Voltage Test Test voltage is gradually increased to measure variations of insulation resistances and leak currents under different voltages. Two types of stepped voltage values are optional, and measurement time can be selected for respective stepped stages. Display of PI (Polarization Index) and DAR (Dielectric Absorption Rate) Able to automatically measure parameters of PI and DAR. Measurement of Hot Line Voltage Able to measure AC and DC voltages AC: AC50 750V, Frequency: 50Hz/60Hz DC: DC±50 ±1000V Precision of Measurement: ±5%rdg.±5%dgt Temperature Measurement 10 70°C Precision of Measurement: ±1.5°C Data Storage Function Able to manually store 100 groups of data, and also able to automatically record 10 groups of data, with each group able to store 360 measurement points in maximum. Data Uploading Function Able to upload the store data into PC through USB interface, to be formed into graphic charts and to be printed for filing, and also able to set up and modify measurement parameters at PC end. Supports USB2.0 (Full Speed) Parameter Indicators Environmental Range of Temperature and Humidity: 0 40°C, 90%rh below (non-condensed) Display: LCD Display, with Back Light Display Refresh Rate: 1 Time/s (0.25 T/s during use of average value function) Output Voltage Monitoring: 2 Times/s Voltage Measurement: 4 Times/s Temperature Measurement: 1 Time/s Analog Bar: 2 Times/s Battery: 6# Battery x 6 | Ni-MH Chargeable Battery, 7.2V Max Rated Power: 15W Time for Continuous Use: Dry batter can last 5 hours and chargeable battery can last 9 hours, under the condition of 5kV generation, +/-ports disconnected and back light closed. Max Rated Voltage to Ground: 600Vrms(CAT IV),1000Vrms(CAT III) Insulation Level: AC7000V 15s between electrical loop and casing. Features 1)Test Voltage and Insulation Resistance Measurement in Broad RangeTest voltage ranges from 250V to 5kV, in 25V stepped setup, and able for measurement of 5TΩ insulation resistance in maximum. 2)Supports Various Insulation Judgments Able for computation and display of PI (Polarization Index)and DAR (Dielectric Absorption Rate), as well as stepped voltage test (five steps, with voltage and time for each step adjustable), temperature compensation, temperature measurement, leakage current display, and other insulation judgment functions. 3)Data Storage and Upload Function Able to manually store 100 data, automatically record 10 groups of data (360 measurement points in maximum for each data group), and automatically record date and time. 4)Carrying Case Hard carrying case adaptable to field application is adopted. 5)Chargeable batteries can be used at the same time Able to be loaded with 2# batteries and chargeable batteries at the same time, and when capacity of one group of batteries is insufficient, it can be switched to another group for further use.
