A tap changer is a connection point selection mechanism device along a power transformer winding that allows a variable number of turns to be selected in discrete steps. A transformer with a variable turns ratio is produced, enabling stepped voltage regulation of the output. The tap selection may be made via an automatic or manual tap changer mechanism.

Power Transformer is an electrical transformer which receives voltage from power system and delivers in another form of voltage i.e. High voltage to Low voltage and vice versa with same frequency. Mainly it receives low voltage with high current and transmits high voltage with low current. It is primarily used in Substations and Power Generation Stations.

The in-house developed and manufactured on load tap changer (OLTC) is featured with integrated design, liquid (transformer oil) insulation and transition resistors. It is used to change transformer taps under workload and adjust the output voltage. It is very essential to maintain the system voltage within prescribed limits for the better health of electrical equipment’s by improving the quality of power supply. The product, a high speed resistor type is designed for use in 3 Phase distribution and Power grid transformers.   Features: Simple Geneva device operating mechanism Top quality components that ensure reliable performance Several features are incorporated within the mechanism to promote long service intervalsand reliability. Economy in design Solid wiping contact used to control the surface film on the contact. Draw out / Replaceable type electrical control wiring Tap changers are type tested as per IS 8468/1977. Our OLTC have reasonably sized side flange, so that we can replace entire power switch components without dismantling the OLTC from the transformer. Our OLTC tanks are sand blasted and powder coated to 100 micron thickness so that they are scratch proof and long lasting. Compact size reduces overall space requirements in transformer to ensure cost effective solutions. The design and manufacture of equipment is subject to constant improvement

The on-load tap-changer vacutap® avt with vacuum interrupters and integrated motor drive serves as switching element and for setting the ratio of dry-type transformers under load.
