Product Feature And Application

1.Measurement of Load Loss:

It displays three-phase voltage, three-phase current and three-phase power, automatically calculates the impedance voltage percentage of the transformer, converts it to the load loss at the rated temperature and rated current, and automatically determines the core model of oil-immersed or dry-type distribution transformers, which is convenient for on-site users to use.

2.Measurement of no-load loss:

The instrument displays three-phase voltage, three-phase current and three-phase power. It shows the distortion rate of the applied power supply waveform, automatically calculates the no-load loss of the transformer after converting the no-load current to the rated voltage and correcting the waveform distortion, and displays the model of the core of the oil-immersed or dry-type distribution transformer.

3.Single-phase measurement:

It can be used to inspect the defects of single-phase transformers or in situations where there is no three-phase electricity on site. The instrument can record the data of three single-phase measurements and calculate the no-load current, no-load loss, impedance voltage and load loss of the transformer according to different connection methods.

4.Measurement of Zero-sequence Impedance:

The measurement of zero-sequence impedance is applicable to transformers with a neutral point in star connection 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.Capacity Measurement:

The instrument is equipped with a built-in rechargeable lithium battery and can output a three-phase sinusoidal inverter power supply by itself. The output voltage is automatically adjusted and it features soft start and soft stop functions. Without any external power supply, it can measure the capacity of distribution transformers and determine their models. At the same time, it displays the transformer impedance voltage and the load loss converted to the rated temperature and rated current.

6.Within the allowable measurement range of the instrument, direct measurement can be carried out. Beyond the measurement range, external voltage and current transformers can be connected. The instrument can set the transformation ratio of the external voltage and current transformers and directly display the values of the applied voltage and current.

7.The instrument is equipped with a harmonic analysis function, capable of measuring the content rate of multiple harmonics and the total distortion rate, and is displayed with the original waveform and bar chart.

8.The instrument adopts a large-screen LCD display, which can show three-phase voltage, three-phase current, three-phase power, three-phase average voltage, average current, three-phase total power and related data on the same screen.

9.AC/DC dual-purpose: Powered by lithium battery or 220V(50Hz) /110V(60Hz) AC charger, adaptive.

10. Intelligent charging management, remaining battery power display, low battery alarm, automatic backlight adjustment to save power.

11.Non-volatile clock and date display; The data storage methods are divided into local storage and USB flash drive storage. Among them, local storage can store 200 test data items, and local storage can be transferred to a USB flash drive. The data stored on the USB flash drive is in Word format and can be directly edited and printed on the computer.

12.Thermal printer printing function, fast and silent.

13.The human-machine interaction interface is more user-friendly: The status bar at the top of the screen displays the insertion status of the USB flash drive in real time. When operating an unconnected device, a corresponding unconnected prompt message is displayed.
