Product Name: Power Transformer C & Tan Delta / Insulation Power Factor Tester (CDEF) Model NO.: WGSL-4C Customized: Non-Customized Type: Tan Delta Tester Usage: Electric Component Tester Tan Delta Test Set: Tan Delta Tester 10kv/1A Trademark: GOLDSOL Transport Package: Aluminum Box Inside and Plywood Case Outside Specification: CE Origin: China HS Code: 903033200 Product Description IntroductionInsulating dielectric loss measurementof transformers, transformers, reactors, capacitors, and bushings, surge arresters is a very basic test method can effectively find the overall damp insulation deterioration and local defects of electrical equipment. It is widely used in electrical manufacturing, electrical equipment installation, transfer and preventive tests.WGSL-4C Automatic Frequency Dielectric Loss Tester bridge broke through the traditional measurement, adopting variable frequency power supply technology, SBC and modern electronic technology of automaticly frequency conversion, A / D conversion and data operations; It has the characters of good anti-interference ability, fast test speed, high precision, fully automatic digital and easy to operate; It has a high-power switching power supply to output 45Hz and 55Hz pure sine wave, providing up to 10 kV voltage; It can automatically filter out 50Hz interference suitable for testing at substations and other fields of large electromagnetic interference.Technical parameters1. Input: 180V ~ 270V AC, 1-phase, 50/60Hz ± 1%;2. Test voltage: 0.5 ~ 10 kV, user-selectable (model no.WGSL-5: 0.5-12KV)3. Test current: 200 mA maximum4. Accuracy:Capacitance: +1% of reading + 1pFTan: +1% of reading +. 00040Voltage: +1% of reading.5. Interfernce Supression:Ratio of interference current to specimen current: 2: 1Line frequency modulation technique either by:1) Fixed Frequency measurement:45, 50, 55, 60, 65Hz; User-selectable or2) Dual frequency measurement with automaticAveraging: 45/55Hz, 55/65Hz, 47.5/52.5Hz; User- selectableMeasurement modesUST (Ungrounded specimen test)This test is made when the specimen can be insulated from ground.The test is often used to reduce the effect of stray capacitance Losses to ground and to reduce the effect of interference pickup from nearby Energized apparatus.Typical test specimen include the primary to secondary winding insulation in high Voltage transformers and measurements on HV bushings with a capacitance tap.GST (Grounded specimen test)This is the most frequent used test connection and involves all insulation between The high voltage conductor and ground. Typical test specimens include transformer Windings to tank and core, circuit breaker assemblies, coils of rotating machines, etc.GST-g (Grounded specimen test with guard )This test is used to separate the total values of the GST into separateParts for better analysis. Often this test is used with the GST to confirm the testReadings made using the UST7. Test DurationTypically 40 Seconds, fully automatic testing.The unit automatically ramps up to set test voltage, take measurement, ramps down Voltage to zero and prints out test result.Measurure rangeTest capacitance range @ 50 Hz / 60Hz.1) Internal power supply 200 mA max.3pF ~ 60000p F @ 10kV60pF ~ 1µ F @ 0.5kV2) External power supply, 5A max.3pF ~1.5µ F@10kV3) Resolution: 0.001pF, 4 digitsTgδ Range: Unlimited, resolution. 0001% Voltage: 0~10kV, it can automatically identify capacitance/Inductance/Resistance.Current: 10µ A~5A9.
