On Load Tap Changer

On Load Gears offers On Load Tap Changer, Type RMV. RMV type OLTC is a single compartment design, with a selector switch mounted inside the transformer tank. It works on the principle of high speed transition resistance and is suitable for both star and delta connected transformer with linear or change-over (coarse fine/reversing) type tapping arrangement. The tap changer follows the principle of flag cycle, making it suitable for bi-directional flow of power. The OLTC has a maximum current and voltage ratings of 200 A and 132 kV respectively and it may be used on delta connected transformers up to 80 MVA ratings. It can give a maximum of 23 positions when connected with a change over. The compact design and less oil requirement is an added advantage to this tap changer. On Load Gears was started in 1983 to manufacture OLTCs as a spin off from a company that had existed from 1967. The founders of OLG have 40 + years business experience. Through the last 29 years of existence OLG has expanded its product line to include not only all varieties of tap-changers for the domestic and international markets but also vacuum circuit breakers, weldable transformer bushings and most recently capacitor switches.
