Product Description:

• The Ground Relay Circuit is intentionally connected to the locomotive frames.
• Therefore, any generator imbalance condition or accidental contact with the frame will result in current flow through the frame between the intentionally grounded GR circuit and accidental ground in the locomotive circuit.

• The same technology has been adopted in P4 and G4 locomotives.
• However, the timing of this event is a bit different with EM2000 control.
• Specially, each GR event is now timed individually irrespective to any other event.
