Abstract
A mobile environment-controlled unit, such as an over-the-road compartment trailer, having an environmental-control system, such as a refrigeration unit, powered by an alternator and having a high-voltage alternating current (AC) bus. The unit incorporates a high resistance ground scheme and can incorporate a solid-state input module to detect phase-chassis faults. This combination provides an improvement in protection for mobile applications that cannot have a voltage reference (or neutral point) solidly connected to earth ground.
