The TCC300 is a microprocessorbased package suitable for substation transformers with onload tap changers The TCC300 digital tapchanger controller is dedicated for metering monitoring and operational control of stepvoltage load tap changers It can be easily integrated to replace old onload tap changer controllers or for new installations requiring stateoftheart features.

Transformer Tap Changer Controller

Today there are three ways to control the Load Tap Changer (LTC) One the LTC can be controlled using a designated device the Voltage Regulator Relay (VRR) which is currently the most common method for many utilities According to the Standard IEEE C372 the device number for the VRR is 90 [1] Author Nelli Sichwart Ahmed Eltom Gary KobetCited by Publish Year 2013.

Transformer Taps are generally provided on HV winding as it is easier to work with low current compare to LV winding Transformer tap position control the secondary side output voltage Tap changer operation V2/V1 = N2/N1 V2 = (N2/N1)*V1 Since V1 and N2 are constant V2 can be regulated by change in N1.
