Transformer Tan Delta and Capacitance Dielectric Loss & Dissipation Factor Tester

Transformer Tan Delta and Capacitance Dielectric Loss & Dissipation Factor Tester

Short Description:

ITEM: RUN-ZC8820S

The Tan Delta is a measure of the dielectric loss when the dielectric is subjected to an AC electric field.

The AC field is a result of voltage applied between a conductor and the outer capacitive foil in the case of the bushing or C.T. and for transformers between the conductor and the tank or core or other windings.

Advantage: 1. Automatic and intelligent measurement

2. Stable under strong interference

3. Competitive price and fast shipping

4. MOQ is Just one set and one year warranty

Features of the Capacitance & Dissipation Factor Test Set

1.  Using frequency conversion anti-interference technology, accurate measurement even under 200% interference, and the test data is stable, suitable for on-site anti-interference dielectric loss test.
2.  Adopting frequency floating, digital waveform analysis, and bridge self-calibration technologies, combined with high-precision three-terminal standard capacitors, ensure a high-precision dielectric loss measurement, and the accuracy and stability of the positive and negative wiring measurements are consistent. The input resistance of all ranges of the instrument is lower than 2Ω, which eliminates the influence of the additional capacitance of the test line. It can be connected to an oil cup for precision dielectric loss test of insulating oil, and can be connected to a solid material measuring electrode for precision dielectric loss test of insulating material.

3.  Automatically identify 50Hz/60Hz system power supply, support generator power supply, even if the frequency fluctuates greatly, it can be measured normally. The built-in series and parallel dielectric loss measurement models are fully compatible with the calibration table and dielectric loss standard, which is convenient for instrument verification.
4.  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.
5.  With an external standard capacitor interface, it can automatically track the frequency of the external test power supply from 40Hz to 70Hz, and support industrial frequency power supply and series resonance power supply for large-capacity high-voltage dielectric loss test.
6.  Multiple safety protections to ensure the safety of human and equipment.
7.  Built-in Micro-printer
8.  Internal storage up to 100 sets.
