Can a capacitor hold open an ac relay?
No, because as soon as a load is connected across a capacitor it will discharge. You need a continuous voltage supply across the coil of a relay to keep it energized. Yes. A large capacitor, 10000 mfd, can hold open a small relay for a few seconds, plus or minus, depending on your varibles.
When is thermal relief required on a liquid line?
Thermal relief is required on any liquid line where there is heat input and the line does not have an open path to flow to in the event of a failure scenario (blocked outlet, instrument air failure, general or single power failure, etc.). A classic example is the blocked outlet case of the cold side of a shell and tube heat exchanger. If the cold side flow is blocked between the discharge of a pump and the outlet of the exchanger the heating medium will continue to transfer heat and the liquid will expand and have the potential for thermal relief. Thermal relief is also required for cooling water exchangers on the cooling water side; however, some facilities keep administrative controls (car sealed open valves) on the cooling water lines to ensure such as scenario does not occur. These facilites would not typically provide thermal relief devices on their cooling water exchangers.
How can you stop high-heeled shoes from clicking on hard floors?
Here are some suggestions: If you go to a shoe store they have little rubber pads that are glued on to the heel of the shoe. This should stop it clicking for a while. The pads are used to keep the heels from wearing down. There is a cheap way, duct tape. You can walk a little on your tip toes. My friend used to stick non sticky gum and it never clicked, or you could just put glue on the bottom let it dry and it will be a lot quieter. You will barely hear it them.
How do you prevent Rusting on mild steel?
By means of passivation in particular yellow passivation we can prevent the CRS from rust. Right ?
What is the function of an under voltage relay?
under voltage relay is used to protect the electrical equipment from the low voltage below the rated voltage till 80% of the network potential. u/v relay is used to give a signal to emergency generator to start whenever the system voltage drops below (80%). U/V relay number is (27) which is available in most electrical circuits to protect the following circuits by insulating them whenever the low voltage occurs: LV/MV switch boards. Motor feeders Generator Circuits Transformer circuits u/v relay is considered to be one of the main protective relays in electrical design.
Why does the turn signal relay on your 1993 civic EX keep clicking?
Sir, The most likely case concerning your 93 civic blinker relay clicking is that inside a relay is two "flappers" that make contact on and off at a set rate that the cars computer or solenoid is set at. For example, I own a 93 civic LX, and my blinkers also click every time the light illuminates. But this monotonous tone is in almost every vehicle on the road. The way a relay works is actually quite complicated but its job function is fundamental. Theres two sets of "switches" in a relay. when you pass 12VDC through one pair of contacts, this triggers a switch inside to close the circuit of another pair of terminals, that's designed to give positive OR negative to a particular device. For Instance, your blinker. That monotonus "clicking" is the sound of those contacts making contact with metal surfaces in the relay. I hope this helps!

Why does the 59n relay keep tripping the breaker?
The 59 relay is an overvoltage relay. The 59N relay is an overvoltage relay for the neutral circuit. Check neutral and make sure the system is properly balanced.
