This Capacitance and Tan Delta Tester adopts variable frequency power technology, single chip and modernized electrical technology to carry out automatic frequency shift, analog-to- digital conversion and data computing. It features strong anti-interference capacity, high test speed, high precision, automatic digitization and easy operation. It adopts high -power switching power supply, which outputs 45Hz and 55Hz pure sine wave and automatically increase the voltage to a maximum value 12kV. The tester is applicable to the site test of substation and other places with large electromagnetic interference. This method is extensively applied in dielectric loss measurement of transformer, mutual inductor, reactor, bushing, capacitor, arrester and others equipments in
power industry.
Functions and Features
- The instrument adopts complex number current method to measure capacitance, tan delta and other parameters. The measured result is highly accurate and it is easy to realize automatic measurement
- The instrument adopts variable frequency technology to eliminate 50Hz/60Hz power frequency interference. So, a reliable data will be reachable even under the strong electromagnetic interference:
- Digital backlit LCD display
- The instrument is easy to operate and the measuring process is controlled by microprocessor
- The instrument is designed to be an integrated model with reference capacitor and HV power supply in it
- External oil cell to test tan delta of insulating oil (optional).
- Multi test mode: UST/GST/CVT/GSTg
- Internal automatic memory/printer /RS232 port.
- 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.
- GST measurement adopts ivddv technology to ensure the stability of test data in GST measurement.
- 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.
- The instrument has a function of measuring high-voltage dielectric loss. It can carry out dielectric loss test with over 10kV with the help of voltage transformer or series resonance.
- Multi protection functions
- PC software can automatically generate test report in Excel format.
