JYR Touch Screen Automatic Dielectric Loss Tester

Product Introduction:

The main purpose of this instrument is to measure transformer loss parameters and accurately measure various parameters such as no-load loss, no-load current, load loss, impedance voltage, etc. The instrument has the advantages of small size, light weight, high measurement accuracy, good stability, and easy operation. It can completely replace the traditional method of measuring transformer loss using multiple meters, with simple wiring, convenient testing and recording, greatly improving work efficiency. It uses a large screen image LCD as the display window (with two configurations of color and monochrome, users can choose freely), graphical menu operation and Chinese character prompts, and a display interface that integrates multiple parameters on one screen. The human-machine dialogue interface is friendly, easy to use, and fast.The structure consists of two parts: the main unit and the accessory box. The main unit is the core of the instrument, and all electrical parts are inside the main unit. The main unit outer box adopts a high-strength imported waterproof injection molded chassis, which is sturdy and durable. The accessory box is used to place test wires and tools. Using digital synchronous sampling technology, accurately measure the true effective values of parameters such as voltage, current, power, power factor, frequency, etc. of three-phase electrical equipment, with a measurement accuracy of 0.5 level. This instrument is mainly suitable for testing the no-load and load characteristics of power transformers. It can replace nine pointer instruments of the same level and is an ideal replacement product for traditional electricity testing instruments.

Product Features:

Capacity measurement: The instrument is equipped with a rechargeable battery and can output a three-phase sine wave inverter power supply. It does not require any external power supply to measure the capacity and determine the model of the distribution transformer. At the same time, it displays the transformer impedance voltage and the load loss converted to rated temperature and rated current;
Measurement of no-load loss: The instrument displays three-phase voltage, three-phase current, and three-phase power. The instrument displays the distortion rate of the applied power waveform, automatically calculates the no-load loss of the transformer converted to rated voltage and corrected for waveform distortion, and displays the model of the distribution transformer iron core;
Measurement of load loss: Display three-phase voltage, three-phase current, and three-phase power, automatically calculate the impedance voltage percentage of the transformer, convert it to load loss at rated temperature and rated current, and automatically determine the coil model of the distribution transformer;
The instrument has a large screen LCD display that can display 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. Instrument Chinese menu, Chinese prompts, easy to operate;
The instrument is equipped with a 232 interface, which can communicate with a computer through a data cable. The instrument comes with a built-in printer that can print and display data. It also has a built-in memory that can store up to 20 sets of data, including calendar and clock functions.
