Capacitance tester HDJS-8000

dielectricdissipation factorfor transformers

HDJS-8000 Transformer Capacitance Tan Delta Tester is a automatic on-site tester that is designed to measure dielectric loss（tgδ）and the capacitance （Cx） of electric equipment. The measure result can be displayed on the LCD screen and printed by micro-printer .It’s suitable for testing on transformer, capacitor, insulating bush, CT/PT, MOA . Features 1. The instrument adopts complex number current method to measure capacitance, dielectric loss and other parameters. The measured result is highly accurate and it is easy to realize automatic measurement. 2. The instrument adopts variable frequency technology to eliminate 50Hz/60Hz power frequency interference. The measurement data will be get even under the strong electromagnetic interference. 3. The instrument is easy to operate and the measuring process is controlled by microprocessor. Once a suitable measuring method is selected, the data measurement will complete automatically under the control of microprocessor. 4. The instrument is designed to be an integrated model with reference capacitor and HV power supply in it, enables site test measurement and reduces site wiring. 5. The instrument is equipped with CVT testing function, which can achieve CVT self-exciting testing without external accessories and measure the capacitance and dielectric loss of C1 and C2 by at a time. 6. GST measurement adopts ivddv technology to avoid unstable data provided by previous GST measurement. 7. The instrument provides low voltage shell function of GST. When the bus of 220kV CVT is grounded, dielectric loss measurement can be conducted for C11 without removing 10 kV GST.
