HZKZ-50A Transformer Empty Load And No-Load Losses Test Equipment
HZKZ-50A Transformer Empty Load And No-Load Losses Test Equipment
I. Overview
The HZKZ-50A Transformer No-Load Characteristic Tester is the latest product from Huazheng Electric Manufacturing (Baoding) Co., Ltd. Equipped with a mainstream ARM processor running at a base frequency of 168 MHz and 128 MB of built-in memory, the device also supports expandable storage up to 4 GB via a memory card. It features a 7-inch high-definition color touchscreen combined with an emWin graphical interface, providing an intuitive and user-friendly operation experience that eliminates the need for an external keyboard. The tester includes a built-in database function, allowing data to be exported via a USB flash drive or transferred directly to a computer using a data cable.
The circuit design of this instrument is exquisite and unique, which makes it superior in performance, powerful in function, small in size and light in weight. It can not only be used to test the on-no load parameters of transformer, but also measure the harmonic content and waveform in the field. The instrument can record the test curve of transformer under on-no load condition, then provide reliable basis for transformer fault analysis.
