On-load tap changer
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. On load tap changers may be generally classified as either mechanical, electronically assisted, or fully electronic.
These systems usually possess 33 taps (one at centre “Rated” tap and sixteen to increase and decrease the turn ratio) and allow for ±10% variation (each step providing 0.625% variation) from the nominal transformer rating which, in turn, allows for stepped voltage regulation of the output.
We guarantee to keep the level through the utilization of standard fittings such as the two earthing terminals, air release device, and breather. Adding to this we also design our transformers with oil level gauge, drain cum sampling valve, oil filling hole, thermometer pocket, lifting lude, explosion vent device, filter valve, arching horns and off circuit tap charger which are the basic parts of a good transformer. Besides the standard fittings, we also give various pools of options to our clients which could be customized as per the needs.
