รายละเอียดสินค้า
PROVA1660 : เครื่องวัดอัตราส่วนจำนวนรอบหม้อแปลง, 1เฟส และ 3 เฟส
Features ▪ Measurements of 1Φand 3ΦTransformer/VT/CT Turns Ratio. ▪ VT/PT ratio 0.8~10000, CT ratio 0.8~2000. ▪ Graphical and Literal Illustration of Measurements and Connections with Large Back-lighted Dot Matrix 240 x 128 LCD. Display Test Data with Nameplate Transformer Values for Easy Interpretation. ▪ Ten Test Frequencies (50~400Hz). ▪ Display Turns Ratio, Deviation, Secondary Output, Excitation Voltage and Current, Phase Angle and Nameplate Transformer/VT/CT Values in one page for easy transformer quality interpretation. ▪ Check for Live Test Points, Short Circuit, Open Circuit, and Reverse Polarity before Each Measurement. Message is displayed to Warn Users (But, checking is not performed once measurement starts). ▪ Store 4096 Files of Transformer Nameplate Values (VT/PT/CT, 1Φ/3Φ, Test Frequency, Primary and Secondary Voltages or Ratio, RCF) and Measuring Data. ▪ 9 types of 3Φ Windings Connections pre-installed for easy user selection. ▪ Wireless Blue Tooth Communication with PC. ▪ Select Filter to Remove Field Noise (Slow, Normal, Fast). ▪ Disable or Enable Auto-Power-Off with Programmable Time. ▪ Built-in calendar clock. ▪ Records with Date and Time Stamp. ▪ Powerful Lithium Battery (3400mAH) with built-in Charging Circuit. ▪ User Programmable RCF (Reference Correction Factor, 0.99~1.01) to Correct Accuracy within 1% Error. ▪ Friendly File System for Easy On-site Data Retrieval and Nameplate Values Management. ▪ PC Application Software included. Electrical Specifications: Reference Conditions:23℃ ± 5℃ (30 to 50% RH) range. Add 25ppm/℃ for 0° to 18℃ and 28° to 50℃ to all accuracy specifications. No external electrical or magnetic fields. Output current ≦150 mA for VT/PT and ≦50mA for CT. Calibration cycle is 1 year. Accessory 1. Test leads (set of 2) 2. Alligator clips (4pcs.) 3. Rechargeable lithium battery 4. User manual 5.
