Abstract
Electrification in transportation is gathering pace with several initiative like the more electric aircraft. In order to improve the availability of electrical power systems in aircraft applications, the use of an ungrounded IT system is proposed with the benefit of guaranteeing operation even in the case of a single insulation fault to ground. An insulation monitoring device is proposed to continuously monitor the insulation resistance and provide support for any preventative maintenance. Extensive simulations and experimental validations are presented to support the concept.
