CPF-10 Capacitance and Tan Delta Tester

• Large LCD  display

The instrument is equipped with a 7-inch large-screen touchable color display, an touch operation interface. The operation is simple, and each process is clear and understandable. The operator does not need additional professional training to use it. Just a gentle click can complete the entire process measurement. It is currently a very ideal intelligent dielectric loss measurement device.

• Massive data storage

The instrument is equipped with a calendar chip and a large-capacity memory. It can save 100 sets of data. The detection results can be saved in chronological order and can be viewed at any time. And it can be printed out.

• Scientific and advanced data management

The instrument's data can be exported through a USB drive and viewed and managed on any PC.

• Multiple testing modes

The instrument can use various methods such as internal high voltage, external high voltage, internal standard, external standard, positive connection method, reverse connection method, self-excitation method for testing; in the case of external standard external high voltage positive connection method, it can measure the dielectric loss of high voltage (greater than 10kV) of CVT.

• No need to remove high-voltage leads to measure CVT

The instrument can accurately measure the dielectric loss value and capacitance value of CVT without removing the high-voltage leads.

• CVT reverse connection shielding method for measuring C0

The instrument can use the reverse connection shielding method to measure the dielectric loss value and capacitance value of the upper end C0 of CVT.

• High-speed sampling signal

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

• Multiple protection and safety reliable

The instrument has multiple protection measures such as input voltage fluctuation, high-voltage current, output short circuit, power failure, overvoltage, overcurrent, temperature, etc., ensuring the safety and reliability of the instrument. The instrument also has a grounding detection function to ensure that equipment not grounded is not allowed to operate and start the test. In case of accidental connection of 380V power supply on site, it has an alarm function to protect the instrument from damage.

• CVT testing in one step

This instrument can also test the dielectric loss and capacitance values of the C1 and C2 of fully sealed CVT, achieving simultaneous testing of C1 and C2. It can also test the transformation ratio and voltage angle difference of CVT.

• LCR automatic measurement

Automatic measurement of inductance, capacitance, and resistance, with angle display.•
