4. Guide line for switch control
The controller complies with the control ruleof the shape of” # “, the users can reset the upper or lower limit for eachphase and reactive power.
1) The controller is in the state of auto switch when the voltage is between UL and UH. (UL is under voltage threshold for the users, UH is over voltage threshold for the users)
2) It can be blocked when the voltage is lower than UL. It can not be put into use when the lack of reactive power, and the parts that have been put into operation should be cut off, it can be unblockedand returned to the state of auto switch when the voltage is higher than UL.
3) It can be blocked when the voltage is higher than UH. It can not be put into use when the lack of reactive power, and the parts that have been put into operation should be cut off, it can beunblocked and returned to the state of auto switch when the voltage falls backto UH-6.
4) In the state of auto switch, the controller measures on-load reactive power, if the value of on-load inductive reactive power is larger than the set value of switch on, then the capacitor switches in, the capacitor will switch out if the capacitive reactive power is more than the set value of switch off.
- Q: and how does its work?
- It will basically provide safety protection from electrical shock. Occassional large electrical equipment may become temporarily energized --- maybe a down power line, or by accident. By grounding the equipment, the earth that you are standing on, and the equipment will always be at the same voltage. Therefore, even if the equipment becomes energized at 25000 Volts, the ground you are standing on will be at 25000 volts as well. So there is no potential difference and therefore, no electrical shock. Without the earth connection --- there would be a 25000 Volt potential difference, and you would suffer severe electrical shock, or even death. Excerpt from Wikipedia: Ground or earth in a mains (AC power) electrical wiring system is a conductor that provides a low impedance path to the earth to prevent hazardous voltages from appearing on equipment (the terms ground (North American practice) and earth (most other English-speaking countries) are used synonymously here). Normally a grounding conductor does not carry current. Neutral is a circuit conductor (that carries current in normal operation), which is connected to earth (or ground) generally at the service panel with the main disconnecting switch or breaker.
- Q: 1. what is electrical and wiring system?2. what are the factors to be considered in designing an electrical wiring system in buildings?3. what are the possible ways of saving energy when designing an electrical and wiring system in buildings?i just need the experts opinion about this.thanks!
- A building electrical system includes all of the equipment and wiring designed by the electrical engineer. This begins at the utility power connection and includes the service entrance equipment (meter base, current transformer cabinet and main disconnect switch), a main distribution panel (main breaker panel or main switchboard), and branch circuit distribution panels. The electrical system includes all wiring from the connection to utility power to connections to all electrical utilization of equipment. The electrical system also includes building lighting and lighting controls, building premise wiring for computers, computer hub room equipment, security systems, public address/broadcast system, keyless entry system, fire alarm system, and standby and emergency power systems. The main factors to consider is square footage of building, type of occupancy, number of occupants, and applicable local codes, the number of floors in the building, location of exits and stairwells. These considerations are used especially in determining what voltage with which to serve the building and size (ampacity) of service entrance and main distribution panel. These statistics are also important in the design of the fire alarm system. The main ways to save energy is through use of occupancy sensors and daylighting controls for lighting (the latter assumes windows or skylights for introducing daylight). These controls will keep the lights off unless specific areas are occupied, and lighting along with HVAC are the largest electrical loads. Energy costs (both electricity and heating fuel) can often be significantly reduced by incorporating CO2 sensors and variable frequency drives to control air handlers (large fans) rather then running them continuously at a rate to support maximum building occupancy, as is the case in many buildings.

- Q: I am 57 years old. MBA graduate with substantial experience in Electrical equipment maintenance. I have also experience in NDT.
- My guess is that your age is a stigma, though nobody will admit to you that they won't hire you because of your age. They might not even be conscious that they are discounting you because of your age. Look around the office when you go for your interview. Is it filled with younger, or with older people? Do the regular stuff too: Go on the internet and research good interview skills. Practice with your friends. Ask your friends to critique your resume. Look up the company on the internet and come up with some specifics about why you want to work for that particular company. Yeah, that's a good point Your salary expectations might be significantly higher than someone half your age. Better check into that. Also, I have no idea what NBT is. You might edit your question so that people have a better idea of what your experience is. Good luck!
- Q: I have heard, (I can't recall where), that the Earth's natural magnetic field is slowly declining. I have also heard that solar flares can disrupt the operation of electrical/electronic equipment. Would either of these natural phenomena affect the operation of electronic/electrical equipment? Please answer each query briefly, and provide links if possible.
- Electrical/Electronic equipment is only effected by something called Electro Magnetic Interference (EMI). The Earth Magnetic field usually does not create this kind of interference. The solar flares on the other hand can produce EMI. However, there are ways you can protect your electrical equipment from the EMI by shielding the equipment from the source of EMI. The thickness of the shield depends on the frequency of the EMI and the conductivity of the metal that is using as the shield. In general, a good conductor metal is the good shield such as Nickel, Silver, Copper, etc. Another way to protect a electrical component against the EMI is using a high permeability metal (hi-mu metal).

- Q: I'm a physics students and often come up with seemingly stupid questions I can't really find an answer to. If the human body acts as a resistor of around 100 kilo-ohms or more, how is it that I could die by grounding myself with the hot terminal of an electrical outlet?I understand that the average current flowing through me is the product of RMS-voltage over resistancebut this value doesn't seem NEARLY high enough to do any damage much less for me to detect.Thanks!

- Q: HiCan someone tell me what the difference is betweena) turning my TV (or whatever) off on the setb) turning it off at the switch on the wallc) unplugging itWhat I'm reading seems to suggest that only unplugging it really means its off - is that true?
- When you turn off modern Tvs from the remote, it will go to standby mode, there's still electricity on the circuit enough for the memory to remember your settings, like volume, time, the channel you've last watch before turning it off. When you turn off the switch from the wall or unplugging it, the Tv is now completely disconnected from the power source. You may loose personal settings, and when you plug it back on then it may function in the default settings. Leaving it plugged has advantages but surge, lighting, sudden voltage changes may damage it. So when you'll be out for days then unplug it from the AC outlet to play safe.
- Q: i have an old distribution board, dorman smith and the lights are all off one circuit, when i flicked the outside light on it knocked off all the lights but didnt trip the 6amp circuit breaker?? Has the circuit breaker had it? its at least 10 years old?
- I'm not familiar with you system however it can't be as old as the fuse system. In the US people who don't have much experience run into this problem and find that when a breaker is tripped, it looks exactly like one that is not. 1- To see if the breaker is really tripped, try pushing it to the on position and see if moves at all. 2- If it does, turn it off as far as it will go, then turn it back on. 3- Doing this will reset a tripped breaker. 4- If this is not the problem, you need to see if there is electricity coming out of the breaker into the circuit. You should really get an electrician to do this. (have a small screwdriver that lights up when it touches a live wire) there are other testers that have two wires with metal tips that are used to test for live wires. They are not expensive and even a multitester runs less than 10 Euros here in Spain. I use one because I want to know the numbers. The screwdriver cost 60 cents. Again you better get an electrician if you don't know much about electricity and especially if the breaker is ok and that sudden surge you had just happened to blow apart a connection that was loose somewhere in the beginning of you lighting circuit. Good Luck.
