Product descroption:
Transformer capacity tester, is dedicated to power distribution transformer capacity measurement, transformer no-load and short-circuit loss measurement instrument, and has harmonic analysis function, convenient for the on-site power grid quality analysis.
Product function and features:
1.Measurement of load loss:
Display three-phase voltage, three-phase current, three-phase power, automatically calculate the percentage of impedance voltage transformer, temperature conversion), shed the rated voltage, load loss automatically judge the oil-immersed or dry type distribution transformer core model, the alarm test process of adaptive prompt functions, convenient for users.
2.Measurement of no-load loss:
The instrument displays three-phase voltage, three-phase current, three-phase power, the instrument displays the distortion rate of the applied power waveform, automatically calculates the transformer's no-load current converted to the rated voltage and the no-load loss corrected by waveform distortion, and displays the type of oil-immersed or dry-type distribution transformer core.
3.Measurement of single phase:
Can be used to check transformer single-phase defects or used in the absence of three-phase power on site. The instrument can record three single phase measurement data, and can calculate the transformer no-load current, no-load loss, impedance voltage and load loss according to different transformer connection.
4.Measurement of zero sequence impedance:
The measurement of zero sequence impedance is suitable for transformers with neutral points in star wiring on the high voltage side. The instrument can record zero sequence impedance, zero sequence reactance, zero sequence inductance, impedance Angle and zero sequence resistance.
5.Measurement of capacity:
Instrument built-in rechargeable lithium battery, itself can output three-phase sine wave inverter power supply, automatically adjust the output voltage, with soft opening and soft stop function, without any external power supply which can realize the measurement of distribution transformer capacity and judgment of the model, at the same time shows the transformer impedance voltage and temperature conversion), rated power flow load loss.
6.It can be directly measured in the measuring range allowed by the instrument, and outside the measuring range can be connected to the mutual inductance of voltage and current. The instrument can set the ratio of external voltage and current transformer to display the value of applied voltage and current directly.
7.The instrument has harmonic analysis function, can measure the rate of multiple harmonics and total distortion rate, and with original initial waveform and bar chart display.
8.The instrument adopts large LCD display, which can display three-phase voltage, three-phase current and three-phase power, three-phase average voltage, average current, three-phase total power and related data. Display using English menu, English tips, easy to operate.
9.AC/DC: lithium battery power supply or 220V AC charger adaptive power supply.
10.Intelligent charging management, remaining power display, low power alarm, backlight automatic adjustment, save power.
11.No power off clock and date display; Data storage mode is divided into local storage and usb storage,this machine storage can store 200 test data, and the local storage can be transferred to the usb disk; Flash drives store data cells formula is in Word format, which can be edited and printed directly on the computer.
12.Thermal printer printing function, fast, silent.
13.Human-computer interaction interface is more friendly: the status bar at the top of the screen displays the usb drive insertion status in real time
When the connected device performs operations, a message indicating that the device is disconnected is displayed.
14. Small size, light weight, easy to carry and use.
