Product overview

In transformer factory and overhaul during the transformer's no-load and load is the transformer manufacturers and power supply, quality of the electricity sector is detected, reducing power loss of an important pilot project. According to actual needs and conditions of field experiments, developed by our own YDSH transformer loss parameter Tester, test data are accurate, reliable, intuitive interface dialogue, simple operation, easy to carry and other performance characteristics, is the characteristic test of transformer replacement product, is an ideal test equipment and transformer manufacturers in the electricity sector, applies to the construction of energy saving supervision.

Performance characteristics

• 240*64 the instrument using the large screen and backlight LCD display of Chinese characters, transformer direct input of parameters, convenient, intuitive and accurate measurements of electric equipment for three-phase voltage, current, power, power factor, frequency of true RMS measurement precision is 0.2. Display of three-phase voltage, electric current, low voltage, power, power factor, frequency of 20 parameters. Wide linear range, readings are repeatable and stable performance. To ensure accurate measurement of power factor 0.000~1.000, especially suitable for low power factor load testing
• No load or the load test data displayed on the screen all at once; Conversion of data without human load loss, 75 degree load loss values are displayed directly on the screen; No-load test, with average voltage over 400V three-phase automatic latches function, and can be locked at any time, and to unlock the data.
• The instrument has a print function, for it is recorded to save data.
• The instrument can be equipped with RS232 serial port, can be controlled by the computer test and displays the data.
• When the test current 800A, test voltage 500V, this instrument can be directly tested. If you need a larger test current or voltage, external CT or PT.
