Large LCD English display
The instrument is equipped with a 7-inch large-screen touch-color display a large full-touch operating interface, simple operation, and each process is very clear and straightforward. The operator does not need additional professional training to use it. One click can complete measurement of the entire process, which is currently an ideal intelligent medium loss measuring device.
Massive storage data
The instrument is equipped with a calendar chip and a large capacity inside, which can save 100 groups of data, and can save the detection results in chronological order. You can view historical records at any time, and you can them out.
Scientific and advanced data management
Instrument data can be exported via a USB flash drive and can be viewed and managed on any PC.
Multiple modes
The instrument can be tested using various methods such as internal high voltage, external high voltage, internal standard, external standard, direct connection method, reverse connection method, and selfexcitation method. In the case of external standard external high voltage direct connection method, it can perform high voltage (greater than 10kV) medium loss.
CVT measurement without removing the high voltage lead
The instrument can correctly measure the medium loss value and capacitance value of the CVT without removing the CVT high voltage lead
CVT reverse connection shielding method to measure C0
The instrument can use the reverse connection shielding method to measure the medium loss value and capacitance value of C at the top of the CVT.
High-speed sampling signal
The inverter and sampling circuit inside the instrument are all digitally controlled, and the output voltage is continuously.
Multiple protection safe and reliable
The instrument has multiple protection measures such as input voltage fluctuation, high voltage current, output short circuit, power failure, overvoltage, over, and temperature, which ensure the safety and reliability of the instrument. The instrument also has the function of setting grounding detection to ensure that devices that are not grounded are not allowed operate and start testing. There is an alarm function when the power supply is incorrectly connected to 380V on site to protect the instrument from damage.
CVT in one step
This instrument can also test the medium loss and capacitance of C1 and C2 of the fully sealed CVT (capacitive voltage transformer), achieving testing of C1 and C2. This instrument can also test the CVT transformation ratio and voltage angle difference.
LCR fully automatic measurement
Fully automatic inductance capacitance, and resistance measurement, angle display.
Support Bluetooth data query
The instrument is equipped with a Bluetooth module and supports Bluetooth data transmission. The protocol meets theData and Communication Technology Specification for Digital Test Instruments of Electrical Equipment" of the State Grid.
