What is off load tap change?
Tap changer is a device that is used to change the secondary voltage on transformers. It is normally on the HV winding of the transformer. Off load tap changer is designed to change the taps only when the transformer is not charged, while on load tap changer is capable of changing the tap on load too.
What is the difference between off load tap changer and on load tap changer?
An on-load tap-changer must not break the supply to the transformer's windings while the transformer is on load. So it has a 'make-before-break' arrangement with its contacts -i.e. one contact moves to the second tap setting, before the second contact moves away from the first tap setting, while a reactor balances the load currents when the contacts are on different tap settings. An on-load tap changer is motor-driven, and can be operated automatically or manually.An off-load tap-changer does not require a make-before-break arrangement, because it is designed to be operated when the transformer is disconnected.
What is on load tap chenger?
A tap changer is used to vary the turns ration between the windings of a transformer to make minor changes to the secondary voltage. An on-load tap changer enables the turns ratio to be altered without disconnecting the transformer. An off-load tap changer requires the transformer to be temporarily diconnected. On-load tap changers are installed on the high-voltage side of the transformer, where the current is lower.
What is center tap transformer?
Center tap transformer is the such kind of transformer that is made to a point half way along a winding of a transformer.
What main by OCTC and OLTC in the transformer?
OCTC means off circuit tap changer (off load tap changer) and OLTC means on load tap changer. in octc we can change the tap position while the transformer is in off condition only. we can not change the tap position of octc in charged condtion of the transformer. the tap position of octc can be change in deenrgise condion of transformer only means if you nwant to chang the tap position firstly you will have to deenrgise the power transformer then you can change the tap position of octc.while in oltc we can change the tap position of OLTC in charged condition of power transformer. This is the basic diffirence between OCTC and OLTC.generally the OCTC used in single phase generating transformer (G.T.Power Transformer) and OLTC used in three phase powwer transformers like standby transformer and auto transformer in power plants and switch yards. for any other question please mail me at (ashu_uit2007@yahoo.co.in )
What is a plain tap or tee joint?
plain tap or tee joint is one of the types of of electrical wire splices and joints
Which will freeze fastest tap water tap salt water and tap sugared water?
Plain Tap water would freeze fastest.Adding salt or sugar to tap water will cause a depression/decrease in freezing point. Hence it will be harder to freeze the tap salt or sugar water.
Do you need to add anything to their water or is it just tap water?
Nothing needs to be added to animals water. The water is just fine how it is as plain tap water.
Do you think Salt water will have more or less surface tension than plain tap water?
more
In what forms to drink water during day?
Water can be obtained from fruits, as well as just plain water from either the tap or a bottle.
Does a bean seed grow faster in salt water sugar water or tap water?
No, addition of table salt (NaCl) to water used for watering plants will normally kill the plant.
What freezes faster salt water or plain tap water?
Salt in a water solution will LOWER the Freezing Point of the resultant solution. Therefore the Saltwater will have to be cooled to a lower temperature. All other things being equal, that should take longer than the plain tap water.
Who is Daniel Dingel?
Daniel Dingel is an engineer who developed a car that uses plain tap water or sea water as fuel- he also used to work for NASA
Which will boil first salt water or plain water?
salt water boiled first i had to do an experiment and salt water won
