Product Introduction:
It is a series of test transformers developed and produced based on the original similar products with many improvements according to the "Test Transformer" standard. This product is a new type of product developed and produced in accordance with DL/T848.2-2004 "General Technical Conditions for High Voltage Test Devices - Part 2: Power Frequency High Voltage Test Devices".
This series of products has the characteristics of small size, light weight, compact structure, complete functions, strong universality and convenient use. It is particularly suitable for insulation strength tests under power frequency or DC high voltage for various high-voltage electrical equipment, electrical components, and insulating materials in power systems, industrial and mining enterprises, scientific research departments, etc.
It is an indispensable important equipment in high voltage testing. Use power frequency 220V (above 10kVA is 380V) power supply to connect to the XC∕TC (special equipment for test transformers produced by our company, please refer to its specific instruction manual for details) series operation box (cabinet), adjust through the built-in autotransformer (above 50kVA the voltage regulator is external) to output 0-200V (or 0-400V) voltage to the primary winding of the LCSB (G), TDM (G) test transformer. According to the principle of electromagnetic induction, the required high voltage for testing can be obtained on the high voltage winding of the test transformer.
