Description
Product details
Capacitance and Tan Delta Tester is a very basic method in the insulation test, which can effectively find the overall moisture deterioration and deterioration of electrical equipment insulation, as well as local defects. It is widely used in electrical engineering, electrical equipment installation, handover and preventive testing. The measurement of tan delta of transformers, transformers, reactors, capacitors, bushings, arresters, etc. is the most basic method to measure the insulation performance. The dielectric loss tester breaks through the traditional bridge measurement method, adopts the frequency conversion power supply technology, uses the single-chip microcomputer, and modern electronic technology to perform automatic frequency conversion, analog-to-digital conversion and data calculation; achieves strong anti-interference ability, fast test speed and high precision. Fully automatic digitalization and easy operation; power supply adopts high-power switching power supply, output double frequency conversion pure sine wave, automatic rise voltage, can provide voltage up to 12KV; automatically filter out 50Hz interference, suitable for large electromagnetic interference such as substation testing on the spot. It is widely used in tan delta measurement of transformers, transformers, bushings, capacitors, arresters and other equipment in the power industry Features: 1. Multiple automatic double variable frequency for optional, which can effectively resist the frequency interference of test site and ensure the accuracy of test results. Multiple fixed frequency for optional, which is suitable for measurement when powered by generator. 2. 7 "high HD color touch screen with stylus and function buttons. 3.Test mode :UST+GST+CVT+ GSTg 4. When the test voltage is higher than 12KV, the external high voltage transformer can be connected for measurement. 5.When the oil cell is connected externally, the oil tan delta test can be tested. 6. Automatic memory with time/date, up to 1000 test data . 7. Multiple protection ensures instrument and operator safety: high voltage protection, low voltage protection, grounding protection, short circuit protection. 8. Built-in thermal printer 9.USB port , easy to transfer test data to USB memory stick. 10.Powerful PC software automatically generate test report in Excel format. 11.Rugged carrying case protection level IP65. 12.All-in-one and lightweight. Technical specifications: Accuracy Cx ±(1%rdg+1pF) tgδ ±(1%rdg+0.00040) Antiinterference index Frequency conversion anti-interference, in 200% interference can still achieve the above accuracy Capacitance range internal high voltage 3pF~60000pF/12kV 60pF~1μF/0.5kV resolution Max. 0.001pF, 4 dgt tgδ range No limitation, capacitance, inductance, resistance can be automatically identified Test current range 10μA~5A Internal high voltage voltage setting range : 0.5~12kV maximum output voltage 300mA(4 minutes) 100mA(Continuous) voltage rising mode Rise or drop smoothly
