Three-Frequency Test Transformer Device Model Parameter Recommendation - Yangzhou DARUI
DARUI Electric recommends for you
Partial Discharge-Free Oil-Immersed Test TransformerAdopts automatic control technology, with high automation and strong anti-interference capability. It is mainly used to test the insulation level of various insulating materials, insulation structures, and electrical products under power frequency voltage, and also serves as a partial discharge-free power frequency test power supply for transformers, instrument transformers, arresters, and other test objects.
With the rapid development of power technology, high-voltage partial discharge testing has become a mandatory item for factory tests, partial discharge-free tests, acceptance tests, and condition-based maintenance of various electrical equipment (such as cables, large transformers, instrument transformers, GIS combined appliances, etc.).
Features of Partial Discharge-Free Oil-Immersed Test Transformer
1. Strong system integration, complete voltage and capacity series, and comprehensive functions.
2. Low impedance voltage, system impedance not greater than 5%, meeting AC test requirements. Manual control mode, similar to traditional electric step-up/step-down method, with rise/fall controlled by buttons. The equipment automatically detects upper/lower limits and has overvoltage protection.
3. Uses fast electronic protection devices with high reliability. The test result has an audible alarm function. When the test passes or fails, the equipment emits different alarm sounds, allowing test personnel to identify the result directly by the alarm sound.
The partial discharge-free oil-immersed test transformer product is a partial discharge-free power frequency test transformer developed by our factory through introduction and absorption of advanced foreign technology. It is widely used in manufacturers of electrical appliances, cables, motors, transformers, instrument transformers, insulating materials, and related high-voltage components, as well as in high-voltage laboratories of power, research, and universities. It can perform partial discharge and power frequency withstand voltage tests on their products.
