GCSTD-CII power frequency dielectric constant measuring instrument Introduction: The power frequency dielectric constant measuring instrument GCSTD is an instrument that measures the dielectric loss (tg δ) and capacitance capacity (Cx) of various insulation materials, insulation sleeves, insulation liquids, power cables, capacitors, transformers, and other high-voltage equipment. It has the advantages of simple operation, Chinese display, printing, convenient use, no need for conversion, built-in high voltage, and short testing time. characteristic: 1. The instrument has high measurement accuracy and can meet the requirements of oil dielectric loss measurement. Therefore, only a standard oil cup and a dedicated testing line are needed to achieve oil dielectric loss measurement. 2. Adopting frequency conversion technology to eliminate on-site 50Hz power frequency interference, reliable data can be measured even in strong electromagnetic interference environments. 3. The overcurrent protection function ensures that the instrument is not damaged in the event of a short circuit or breakdown of the test sample. 4. Comes with standard capacitors and high-voltage power supply for easy on-site testing and reduces on-site wiring. 5. The instrument adopts a large screen LCD display, and the testing process is both intuitive and easy to operate through Chinese character menu prompts. Technical parameters: Test environment temperature: 10 ℃~30 ℃ (LCD screens should avoid prolonged sunlight exposure) Relative humidity: 20% to 80% Power supply: Voltage: 220V ± 10% Dimensions: Length * Width * Height=470mm * 320mm * 360mm Weight: 16kg Output power: 1.5KVA Display resolution: 3 bits, 4 bits (all internal are 6 bits) Testing methods: forward connection method, reverse connection method, external test voltage method Measurement range: Internal test voltage: tgδ：99.9% Cx ：30 pF＜Cx（10KV）＜60000 pF 10KV Cx＜60000 pF 5KV Cx＜80000 pF 2.5KV Cx＜0.3uF External test voltage: Determined by the output power of the external test transformer Basic measurement error: dielectric loss (tg δ): 1% ± 0.09% Capacitor capacity (Cx): 1.5% ± 1pF Resolution: tg δ: 0.01% Cx ：0.1pF The instrument has an integrated structure for boosting and measuring, with five adjustable output voltages ranging from 2.5KV to 10KV Sample requirements: Diameter of 50MM, 100MM, 38MM
