The 1336-GF-SP6A is a ground fault current transformer, manufactured and designed by Allen-Bradley in order to be used with 1336 Series systems. Grounding transformers are important parts when it comes to preserving the correct functioning of electric distribution systems. The Allen-Bradley 1336-GF-SP6A ground fault current transformer is within the F frame of the series which ranges from 250-450 HP making it compatible with parts that feature the same HP range. Grounding mechanisms provide a neutral point where the main power source is unable to do it. This unit is usually applied to high voltage systems. The Allen-Bradley 1336-GF-SP6A ground fault current transformer is a fundamental part of a grounding system and the main function of this system is to control the voltage range respecting ground and provide a current path that allows us to detect unwanted connections between line and phase conductors. Once an unwanted connection has been detected, it sends a signal in order to trip protection devices and remove the excess of voltage on these conductors. Drives from the 1336 series, are usually mounted in cabinets and ground connections are made at a common grounding point in the cabinet. Normally, this installation provides grounding connections to both the motor frame and drive cabinet ground.

The Allen-Bradley 1336-GF-SP6A ground fault current transformer also has a fault detector mechanism, which means that it has the ability to monitor the whole system, identify when a fault has occurred and pinpoint the location and type of the fault. This is important since it will help improve the process and preserve the life of all the equipment involved in the system.
