Tap Position Indicators : EE-601
Emco Electronics’ Tap Position Indicator Type EE-601 is used to indicate the tap position of the Power Transformer. Resistors are connected between each tap on the tap-changer. The connections from the minimum, maximum and wiper positions coming from the tap-changer are connected to the respective Min, Max and Com terminals marked on the Rear Panel of the TPI.
When the unit is powered on, the display indicates the current position of the Tap-changer. As the tap is increased, the display increases and decreases as the tap is decreased. Check the TPI by changing the tap from position 1 (min) to the max. position and confirm that it reads correctly.
When the wiper is open, the display indicates zero.
