VLF-40kV 0.1Hz Cable AC Withstand Voltage Test System

Details

Introduction

♦Ultra-low frequency insulation withstand voltage test is actually an alternative method of power frequency withstand voltage test. As we know, when power frequency withstand voltage test to large generators and cable, it needs to test transformer or resonant transformers with large capacity because their insulation layer are with big capacitance. Such huge equipment, not only weight heavy, high cost and application is also inconvenient. In order to solve this problem, Power Sections adopt reducing the test frequency, thus reducing the capacity of the test power supply. 

♦0.1 Hz AC withstand voltage test alternative power frequency withstand voltage test, not only can have the same equivalence, but also have much less volume of equipment and greatly reduce the weight.
