Product overview

Active/tester of transformer capacity is developed for the current market conditions, developed high-precision test equipment. It comes with high performance rechargeable batteries without external power supply charging time can be measured 100 times in a row. The internal digital synthesized three-phase reference sine wave signal, low distortion and high stability, effective guarantees the accuracy of the project under the condition of non-rated test data; Through the high efficiency power amplifier output triple high power testing power supply, you can automatically adjust the output voltage and current, can be adapted to different capacity transformer testing and wide range of applications.

Measurement of transformer capacity and an external three-phase short circuit of transformer losses is not required when testing power supply and voltage regulators, current generator, auxiliary equipment, simplified wiring, greatly improving working efficiency; Capacity accuracy up to 100%.

Product name

Capacity/characteristics of transformer testing instrument transformer capacity and load testing, transformer capacity testing equipment, transformer loss parameter Tester, source/transformer capacity testing instrument

Product features

1. Adaptability: the equipment is equipped with a high performance lithium-ion batteries on site does not need an external AC power supply can also work long hours, very suitable for passive situations of situ blackout.

2. Testing is simple: instruments with high accuracy three-phase AC test power supply (three-phase reference sine wave signal is not a simple AC inverter to ensure accurate and reliable testing data), to test transformer capacity without an external test power supply, greatly simplifying the complexity of the test, only the instrument itself and a small amount of test lines on transformer capacity testing is done.

3. Small size, light weight: smallest and only 320mmx240mmx130mm (smaller than similar products by more than half), light weight, only 3 kg (the lightest 10 kg of similar products).

4. Instruments with a battery indicator, to percentage of charge remaining in the liquid crystal display (by no means a simple loss of power alarm), to facilitate users work sustainability to avoid lack of electricity caused inaccurate tests or test data.

5. Transformer capacity testing instrument 10KV And 35KV Levels of standard and nonstandard distribution transformer capacity testing, volume testing range for 10~100000KVA . Non-standard transformers include: furnace transformer, medium-frequency transformers, Rectifier transformers and so on.

6. Powerful: a machine, a device to achieve the functionality of multiple devices.

As the transformer capacity testing instrument can measurement of transformer capacity, through the equipment of high-precision three-phase test of power sources and special calculation method for accurate measurement of capacity.

As transformer loss parameter tester can conduct a variety of transformer no-load test and load test; Test data, including no-load current percentage, load loss, impedance voltage, load loss, and so on.

Electric parameter test instrument precision measurement of electrical parameters of power systems, including: three-phase AC voltage, three-phase AC current, the phase angle between the voltage and current, three-phase power, and so on.

7. Simple, easy to learn and easy to understand, color LCD display; Big screen, high brightness LCD display, Chinese menu and the prompt realization of friendly human-machine interface operation; Users can save the test data and access; Internal clock that shows the current date and time; Test results through micro-high speed printers, allow users to confirm the signing, as a basis for effective treatment.
