When you let water into a bathtub what kind of machine helps you open the tap?
It depends on the faucet but generally it would be a screw or lever.
What other ways to conserve energy?
turn off lightscarpoolturn off the tap when not in useuse cold water instaed of hothave "sleep" mode on your electronics
What is the flow rate of water from a street fed mains tap on a 15mm pipe?
Considering the pressure is 17,000 BAR then its 4,521,906 Liter per nano second
When a transformer secondary lead has been connected to a middle loop that is not an end connector what is it called?
this is a simple ceter tap...however for Y and star systems it may be more complicated. creating different voltage with the same primary's
How can you tell if your motor centrifugal switch is bad?
I cannot be 100% certain that the centrifugal switch on my table-saw motor is bad, but here are some symptoms that I recently experienced: 1) The motor starts fine, but the motor-start capacitor begins smoking (bad sign) while the motor is running. I think this means the switch is sticking closed in this case. 2) Other times, the motor does not want to start at all. If I slacken the drive belt, the motor starts spinning. When it gets up to speed, I can tighten the belt and go ahead and use the saw. In this case, I think the switch is sticking open. I first experienced symptom #1, which led me to believe I had a bad capacitor. I replaced it, but after a few uses, the new capacitor also smoked. Then I noticed symptom #2. After doing a little web snooping, I have nearly concluded that the problem is the centrifugal switch. Just not sure yet how to get to it or find a replacement. . . Bucky K in Ohio
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 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 bet manual off Tap changer and auto tap changer in Distribution Transformers?
automatic tap changing transformers can change their tap setting on their own, manual tap means a person has to manually go out and change the tap setting
Is an on-load tap changer considered as a resistor?
No. All a tap changer (whether 'off-load' or 'on-load') does is to make minor changes to the turns-ratio of a transformer.
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.
Why tap changer is required?
Tap changers are used to change transformer winding ratios by a specified amount (+/- 10%, for example). This allows more voltage control of one side with respect to the other. For a distribution transformer, as load increases, the voltage will sag. If it sags too far, a tap changer will be required to raise the voltage to acceptable values.
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.
How does on load tap changers operate?
On-load tap-changers are operated by an electric motor, often by driving a flywheel mechanism. The operation of the tap-changer is controlled by an AVR (automatic voltage regulator) which monitors the transformer's secondary voltage.
Why was the tap changing panel removed from a transformer?
So that tap-changing can't be done any more, or maybe the tap changer was faulty.
What would an off load transformer tap changer be used for?
to inreases or decreases n. of turns of a transformerAnswerAn 'off-load' tap changer is a tap-changing mechanism that can only be used when the transformer is disconnected, as opposed to an 'on-load' tap-changing mechanism that can operate when the transformer is energised and on load.Tap changing is performed to slightly change the turns ratio of a transformer in order to keep the secondary voltage within the statutory limits (e.g. in the UK, 230 V +10% -6%) should there be a substantial change in load.

How can you change step up into step down without changing winding?
You can't, unless you have a crazy tap changer so you can remove or add windings to change the ratio from N1 > N2 to N2 > N1.
