一种用于电力电缆绝缘测试的新型超低频余弦矩形电压发生器的实现

As an important part of asset maintenance strategy, power utilities carry out insulation testing of power cables to diagnose and assure their health condition. Among various testing methods, very low frequency cosine-rectangular voltage (VLF-CRV) testing is a relatively new approach that has been recently proposed because of its significant advantages of high efficiency, multifunctionality, and ea...
