• Temperature of the primary conductor should not exceed
100°C.
• Dynamic performances (di/dt and response time) are best
with a single bar completely filling the primary hole.
• In order to achieve the best magnetic coupling, the primary
windings have to be wound over the top edge of the device.
• To measure nominal currents of less than 50 A, the optimum
accuracy is obtained by having several primary turns (nomi-
nal current x number of turns < 50 At).
