CTs that are specially designed to match the ground fault input of GE Multilin motor
protection relays should be used to ensure correct performance. These CTs have a
50:0.025A (2000:1 ratio) and can sense low leakage currents over the relay setting range
with minimum error. Three sizes are available with 3½-inch, 5½-inch, or 8-inch diameter
windows.
