Gold Multimeter Tan Delta Capacitance and Dissipation Factor Test Set Dielectric Loss Meter

Principle of Tan Delta Test
A pure insulator when is connected across line and earth, it behaves as a capacitor. In an ideal insulator, as the insulating material which acts as dielectric too, is 100 % pure, the electric current passing through the insulator, only have capacitive component. There is no resistive component of the current, flowing from line to earth through insulator as in ideal insulating material, there is zero percent impurity.

In pure capacitor, the capacitive electric current leads the applied voltage by 90°.

In practice, the insulator cannot be made 100% pure. Also due to the aging of insulators, the impurities like dirt and moisture enter into it. These impurities provide the conductive path to the current. Consequently, an electric leakage current flowing from line to earth through the insulator has a resistive component.

Hence, it is needless to say that, for good insulator, this resistive component of electric leakage current is quite low. In another way, the healthiness of an electrical insulator can be determined by the ratio of the resistive component to the capacitive component. For good insulator, this ratio would be quite low. This ratio is commonly known as tanδ or tan delta. Sometimes it is also referred to as dissipation factor.

JYC has anti interference fuction by frequency conversion during insulation loss testing, and it is not necessary to change wire as CVT testing, and same time JYC can test the turn radio of CVT.

Technical Parameters

Transformer Capacity Characteristics Tester Function

• We can measure a variety of distribution transformer, power transformer capacity instead of the additional power. It is more convenient and efficient.
• Combined with the power, voltage, boost up flow and other equipment, it measures various transformer no-load current, no-load loss, impedance voltage, load loss and so on.
• All results are automatically carried out relevant correction. You only need to input the related parameters (such as temperature, load adjustment coefficients), then the instrument can automatically correct such as waveform deformity correction, temperature correction, correction of non rated voltage, rated current correction.
• The maximum voltage is up to 750V and the maximum current is up to 100A. It is equipped with protection circuit.
• The voltage and current range can be very flexible and easy to expand.
• It has large screen, high brightness LCD display, English menu and operation tips, friendly man-machine interface and wide temperature, brightness adjustable type LCD screen, which can adapt to the different temperature.
• According to the test results of no-load and load loss, it can automatic presume the three-phase oil immersed distribution transformer and power transformer’s performance levels as the reference (this instrument is currently only available for three-phase oil immersed transformer and power transformer performance level code. Others are invalid.
