ELECTRICAL ISOLATION DETECTION WITH ENHANCED DYNAMIC RANGE
A bus terminal is isolated from ground potential during normal operation of the vehicle. A first current is applied to the bus terminal. A current level detector is arranged to detect a first level of the first current, or a corresponding observed voltage level, that exists or flows from the bus ter...

| description | A bus terminal is isolated from ground potential during normal operation of the vehicle. A first current is applied to the bus terminal. A current level detector is arranged to detect a first level of the first current, or a corresponding observed voltage level, that exists or flows from the bus terminal to ground. A compensator is configured to compensate for a range in the detected first level by applying a corresponding compensating voltage level to a first resistor coupled to the current level detector. An electronic data processor is capable of estimating a first isolation level between the bus terminal and ground based on the detected first level. |
