Capacitance Tangent Delta Power Factor Dielectric Loss Tester
I.Introduction:
Tangent delta tester is a high-precision instrument, which can be
applied to automatically measure electrical loss tangent ( ) and capacitance of all kinds of high voltage electrical equipments
on the spot of power plants, substations,laboratory, etc. The
instrument is an integrated structure with a dielectric loss test
bridge, a variable frequency power supply, a step-up transformer
and a SF6 high stability standard capacitor.
II.Features:
★Large LCD display
Simple operation, the instrument is equipped with a high-end full
touch LCD screen, super touch interface, and each process is very
clear. Operators can use it without additional professional
training.
★Mass storage data
The instrument is equipped with a calendar chip and large capacity
memory. The test results can be stored in chronological order.
Users can view historical data at any time and print it out.
★Multiple test modes
The instrument can be tested by high pressure, high voltage,
standard, positive connection method, reverse connection method,
self excitation method and other methods.
★CVT test step in place
The instrument can also test the full sealed CVT (capacitor voltage
transformer) C1, C2 dielectric loss and capacitance, to achieve the
C1, C2 simultaneous test.
★Do not dismantle the high-voltage lead measurement CVT
The instrument can accurately measure the dielectric loss and
capacitance of CVT without dismantling the CVT high voltage lead.
★CVT reverse shield method for measuring C0
The instrument can be used to measure the dielectric loss and
capacitance value of C0 on the upper end of CVT.
★High speed sampling signal
The inverter and sampling circuit of the instrument are all
controlled by digital, and the output voltage is adjustable
continuously.
★Multi protection security
The instrument has many protection measures, such as input voltage
fluctuation, output short circuit, over voltage, over current and
temperature.
