Product FeaturesThe Electric Energy Comprehensive Tester is a portable multi-functional electrical parameter testing instrument developed by our company, with the price of domestic instruments and functions surpassing imported instruments. This tester can perform online detection of all electrical energy parameters of electrical equipment and power frequency lines without power interruption. To support the national resource conservation work, it is designed for the electric balance testing required by the upcoming energy management and transformation.
Using the three-phase vector diagram function, it facilitates users to judge whether the line wiring is correct and whether the line working status is normal, with miswiring judgment function.
Combined with a USB drive, it can fully record and store instantaneous data and waveforms of various electrical equipment, analyze data, draw and print change curves of voltage, current, power (able to distinguish positive and negative power) during the operation of various electrical equipment. This provides correct scientific basis for reasonable adjustment of oilfield pumping unit balance blocks, fan efficiency, coal mine electrical equipment, enterprise electric balance, railway, refrigeration, electric power, chemical, machinery and other industries in production, manufacturing, and energy management. The tester is equipped with a large-capacity lithium polymer battery pack, no external power supply needed for on-site testing; 7-inch TFT color screen displays various data curves; it has advantages such as high measurement accuracy, easy operation, comprehensive functions, and multiple uses in one. It is truly an ideal intelligent electric balance testing tool.
