What is the function of Oltc?

On-load tap changer (OLTC), also known as On-circuit tap changer (OCTC), is a tap changer in applications where a supply interruption during a tap change is unacceptable, the transformer is often fitted with a more expensive and complex on load tap changing mechanism.

Where is Oltc used?

Definition: An On-Load Tap Changing Transformer (OLTC) consists of an open load tap changer, it is also known as an on-circuit tap changer (OCTC). They are used in areas where there is an interruption in the power supply due to an unacceptable tap change.

What is a diverter in a transformer?

Diverter switches of OLTC perform switch over operation between the taps of the transformer, in which they are embedded at a leap. Speeds reached during this process are very high.

What is the use of tapping in a transformer?

Transformers are normally provided with taps to adjust the turns ratio to compensate for this supply variance. This will allow the output voltage to be closer to the rated output voltage when the input voltage is off rated voltage.

What is Oftc in transformer?

Tapping: OFTC(Off circuit Tap Changer) or OLTC(On Load Tap Changer)

What is Oltc and Rtcc?

RTCC stands for Remote Tap Changer Control. As we know the OLTC (On Load Tap Changer) is responsible to change the transformer output voltage. OLTC controls the winding tap position of the Transformer and it resulted in the output voltage also changes.

What is PRV in transformer?

Pressure Relief devices/valves are typically classified in the Transformer industry as safety or protection devices. The device will operate when the inside oil-pressure is greater than that of the set pressure. The device has a directional cover that will allow any hot oil to be safely expelled.

What is CRP in electrical?

A Control & Relay Panel (CRP) solution is designed to control several feeders, through medium voltage indoor and outdoor switchgear in a primary distribution substation. It is typically deployed when associated switchgear does not have space to accommodate the protection, control, and monitoring needs of a substation.
