Oltc And Rtcc Panel Operation Youtube Rtcc panel is used to control the transformer output voltage automatically by changing the oltc tap positions. it is mainly used for the parallel operation of oltcs when multiple transformers are connected to the same bus voltage. it is also used for monitoring of oltc tap position and transformer output voltage as an event record. 3 working function of rtcc panel. rtcc panel is used for voltage regulation on remote mode or auto mode in transformer. it is used two types auto and manual mode. voltage is controlled by in auto mode by automatic voltage regulation relay. the voltage can be regulated by manual mode with the help of push button and selector switch.
Oltc Operation Checking Rtcc Oltc Avr Ict Substation Electri Tap changers are voltage regulation equipment used to adjust the voltage ratio in transformers by adding or removing tapping turns. voltage adjustments can be made by using either on load tap changers or off load tap changers. taps can be made either on the primary or the secondary of the transformers. it is important to maintain the system. The world mainly uses resistor type oltc’s and have done so for 90 odd years. the largest producers of oltc’s – reinhausen and abb offer some very good insight to operation of oltc’s, but if you are an engineer involved with transformers and don’t understand these principles, maybe further training is needed rather than posting stupid. See how to connect to an oltc for remote operation of the tap changer with the rtc or ttru3, find out more bit.ly 2xgijzgwebsite: megger.c. Based on the requirement of output voltage, oltc operates by the drive mechanism in a manual or automatic way through avr (automatic voltage regulating). generally in power transformer, avr relay is used in rtcc (remote tap changer control) panel. as per the command of avr relay, the oltc operates to change the voltage to raise or lower direction.
