Product Description
10KV Insulation Power Factor Tester/Loss Transformer Tester/Dielectric Loss Analyzer
(Mode: CDEF)
Introduction
CDEF fully-automatic anti-interference dielectric loss tester breaks through the traditional bridge testing method and 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 adopts high-power switching power supply, which outputs 45Hz and 55Hz pure sine wave and automatically increase the voltage to a maximum value 10 KV. It can filter 50Hz interference automatically, and it is applicable to the site test of substation and other places with large electromagnetic interference. This methods is extensively applied in dielectric loss measurement of transformer, mutual inductor, reactor, bushing, capacitor, arrester and others equipments in power industry.
The instrument can test the following parameters and display them in figures:
Capacitance value of tested article CX is in pF or nF, 1nF=1,000pF.
Dielectric loss value of tested article tgδ is displayed with %.
Feature
1. Adopts complex number current method to measure capacitance, dielectric loss and other parameters.
2. Adopts variable frequency technology to eliminate 50Hz/60Hz power frequency interference. So a reliable data will be reachable even under the strong electromagnetic interference.
3. Large screen LCD . In the process of testing, English menu prompt is visualized and easy to operate.
4. 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.
5. Designed to be an integrated model with reference capacitor and HV power supply in it, enables site test measurement and reduces site wiring.
7. 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.
8. GST measurement adopts ivddv technology and avoids unstable data provided by previous GST measurement.
9. 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.
10. Measuring high-voltage dielectric loss. It can carry out dielectric loss test with over 10kV with the help of voltage transformer or series resonance.
12. Ground-fault protection function. In case that the instrument is not grounded or grounded incorrectly, the instrument will refuse to enter into normal procedure and output HV. As for the over-current protection function, it will protect the instrument from damage when the tested article is in a short circuit or breakdowns.
13. Electric shock protection. When the instrument operator suffers an electric shock due to incaution, the instrument will cut off the HV immediately and thus ensure the security of operator.
Title goes here.
