rail systems. Given AAC's reputation for reliability and durability, the following areas are a few of the rail and rail transit applications that rely on AAC excellence:

• High accuracy applications, such as current transducers to monitor traction motor forward and reverse regenerative brake current.
• High sensitivity DC current detectors, with built-in relay and field adjustable trip point control, sense ground fault problems anywhere in the system.
• DC voltage detectors monitor third rail power applied to individual cars. The output relay responds when the voltage exceeds the field adjustable trip point setting.
