JHJS560 Different Frequency Automatic Dielectric is a high-precision instrument, which can be applied to automatically measure electrical loss tangent (Tgδ) and capacitance of all kinds of high voltage electrical equipments on the spot of power plants, substations,laboratory, etc. Specialized in tan delta test transformer, 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. High voltage source inverter test generated inside the instrument, the transformer voltage for sample test. At the same time, the utility model is suitable for the occasions that the generator is used for power supply after the power cut. The instrument with insulation cup can test the dielectric loss of insulating oil, and is the ideal equipment for tan delta transformer test in power system detection.
Product Features
Large LCD display
Simple operation, the instrument is equipped with a high-end full touch LCD screen, super touch interface, each process is very clear, the operator does not need additional professional training can be used. Click on it to complete the whole process of measurement, is a very ideal intelligent dielectric loss measurement equipment and professional Tan Delta Test Set.
Scientific and advanced data management
Instrument data can be exported through USB flash drive, and can be viewed and managed on any PC.
Mass storage data
The instrument is equipped with a calendar chip and a large-capacity memory, which can store 200 groups of data, save the test results in time sequence, check the historical records at any time, and print them out.
Multiple test modes
The instrument can use high pressure, high voltage, standard, standard, positive connection method and reverse connection method, self excitation method and other methods can do testing; high voltage in standard high voltage conditions (greater than 10kV) dielectric loss.
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. The instrument can also test the CVT ratio and voltage angle difference.
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.
Automatic measurement of LCR
Automatic inductance, capacitance and resistance measurement and angle display.
Multi protection security
The instrument has many protection measures, such as input voltage fluctuation, output short circuit, over voltage, over current and temperature. The instrument also has the
