DGS-206C Transformer Tangent Delta Tester

Application:

It is a high-precision test instrument used to test the dielectric loss tangent and capacitance of various high-voltage power equipment. It can also test the dielectric loss and capacitance of fully sealed CVT (capacitive voltage transformer) C1 and C2. The instrument can also test CVT ratio and voltage angle difference.

Features:

◆Adopt digital trap technology to avoid the interference of power frequency electric field to the test,frequency can be convert to 50.0Hz, 47.5Hz\52.5Hz, 45.0Hz\55.0Hz, 60Hz,

57.5HZ\62.5Hz, 55.0Hz\65.0Hz, the output voltage is 0.5kV-10kV continuously adjustable.

◆CVT testing in one step

The instrument can also test the dielectric loss and capacitance of the fully sealed CVT (capacitive voltage transformer) C1, C2, and realize the simultaneous test of C1 and C2. The instrument can also test CVT ratio and voltage angle difference.

◆Mass storage of data

The instrument is equipped with a calendar chip and a large-capacity memory, which can save 200 groups of data and can be printed out. Instrument data can be exported via U disk.

◆Multiple test modes

The instrument can be tested by internal high voltage, external high voltage, internal standard, external standard, positive wire method, negative wire method, self-excitation method and other methods.High voltage (greater than 10kV) dielectric loss can be achieved under external standard external high voltage.

◆CVT negative wire shielding method measuring C0

The instrument can measure the dielectric loss and capacitance of C0 at the upper end of CVT by negative wire shielding method.

◆High speed sampling signal

The inverter and sampling circuit inside the instrument are all controlled by digitalization, and the output voltage is continuously adjustable.

◆Multiple protection is safe and reliable

The instrument has multiple protection measures such as input voltage fluctuation, high voltage current, output short circuit, power supply fault, over-voltage, over-current, temperature and so on, which ensures the safety and reliability of the instrument.The instrument also has the function of grounding detection to ensure that ungrounded devices are not allowed to boost voltage.
