To meet the actual demand for power automated nowadays, we have added “Four Remote” intelligent communication function for this kind of product,‘Four Remote’includes telemetering, telecommand, telecontrol and remote regulating, which can be usedas RTU (Remote Transmit Unit).

Micro computer comprehensive protection in HV cabinet of the substation is used for detection of HV side system parameter, and protection and control of HV switch, whichuses CAN bus to communicate, normally the intelligent circuit breaker on LVside has Modbus protocol communication interface, CAN bus on HV side is transformed into 485 bus by protocol conversion module, which communicates with Modbus equipmenton LV side through 485 field bus.

After the wholesubstation achieves “Four Remote”, the background system in the control centercan monitor internal actual motion inside of substation on site and internal switchstatus in real time, and can change internal setting value of each deviceinside of substation and remote control switch at any time.

Wire communication ata traditional communication mode can be used if the substation and controlcenter are close enough. Beside this communication connection type, we alsoprovide GPRS wireless communication to achieve “Four Remote” by GPRS single,which exempt a large number of wire connections between control center andon-site equipments, great convenience to the installation and debugging works, there is no restrictionson installation site as long as GPRS single is available.

Q:I plan on starting college next September to study electrical electronic engineering, it's three years in college then moving onto university. In college I would be B Tech qualified and the awarding body is EAL. Is B Tech qualification good ?What Qualifications will I get out of university ?What's the difference between BEng and MEng ? Could an Electrical Engineer work on oil rigs ?: I have no idea about B Tech. A university will give you either a BSc or BEng (Bachelors degree in Science or in Engineering), which doesn't actually matter much, it's a technical distinction that most employers will ignore. MEng is a masters in engineering, you normally get it from a university that offers a 4 year masters program as a way for students to get a Masters degree (which is normally a post-graduate qualification) while still getting the government funding level offered for undergraduate degrees. In theory these are as good as a true post-graduate degree, in practice they are considered somewhere between a Bachelors and a separate post-grad masters. There may be some small call for electrical engineering on an oil rig but very little, it certainly wouldn't be considered a mainstream source of employment for people with that qualification.

Q:I have a hanging, pull-string electrical light in my attic. This is very standard stuff. I would like to purchase an electrical device that will screw into the electric light and give me an electrical outlet. Think of this as a device with the base of an electric light bulb and an electical outlet instead of the bulb. I thought I saw one in a hardware store 20 years ago, but I have no idea if this product still exists. I can not think of what it would be called with a technical name when searching for one on the Internet.My business application is to be able to plug equipment into my attic rather than running the cord into the main house.: It's called a light socket adapter. There are many places that sell them. Take care not to overload the low-current lighting circuit though !

Q:i got this in a hairdressing assinment and i need to no about it x: safety features of equipment. electrical connexion. must be earthed so no fires can occur or minimise. equipment must be checked every 6 to 9 mths for any electrical fault. etc

Q:And what is an MBA? My sweetie is studying that at a community college will that mean he won't learn as much as if he took it in university?: He engineers electrical things. And Pedro I. Wong may have a very valid point! ;-)

Q:I just moved into an apartment building that apparently has a chronic problem with power surges. The power tends to go on and off several times a week, for no apparent reason. I know I need to buy power surge protectors for all my equipment, but I don't know what type. I've seen surge protectors (multi-plugs) that say 875 joules, 1,045 joules, and so on, but I don't know how to translate that in terms of equipmentFor example, I have a TV, DVD Videocassette player, and high-quality music equiment all plugged into a multi-plug in the living room. Should I buy a multi-plug power surge protector for this area, and what energy requirement should that surge protector have if I'm going to plug all that equipment onto it? What type of a power surge should I buy for my computer? What about the fridge? Air conditioner? Remember, I'm probably going to need to put power surge protectors all over the place, so which would be best for the different types of equipment in a home?Thanks!!!: If I were you I would get a good surge protector and UPS, or uninterruptable power supply. Make sure the surge protector is a quality unit. Actually, I would buy an Isobar surge protector as most UPS units don't have this type of protection. Many are only designed to provide power, not protection. They are good units with real protection. I would then plug the UPS into that. The Isobar will stop surges and spikes (they are different things), and the UPS will protect your equipment from the sudden shut downs and start ups from the loss of power.

Q:I accidentally connected the negative and positive terminals of my battery with a wrench, I have checked all the fuses and none look to be blown. What else should I be looking for?: Do you have electrical power at all, on any thing? You don't say what else it affected. Could be a fuse link burned that controls all the power to the car. If just your lights, some light switches have built in breakers, which shut off the lights when a wire in the light circuit, like a door light, shorts out. This protects the rest of the system. There might be a reset on the switch. But it would be car specific, meaning how to reset it would be in a manual, or someplace, and might require taking the switch out of the dash. If that is not the case, look for a 30 amp fuse which is usually what lights use, that might be blown.

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:and which one to use in my country Egypt ?: NFPA - National Fire Protection Association - National code that covers anything to do with flamable stuff (electrical, dust, combustibles, sprinklers, fire alarms, etc) (United States) NEC - National Electric Code a.k.a NFPA 70 (NEC is a section of the NFPA code) - Addresses proper installation of electrical equipment, devices and wiring(United States) NEMA - National Electric Manufacturers Association- trade organization for electrical manufacturers. Sets common rules, practices and certification for the manufacture of electrical components and devices (United States) IEC - International Electric Code - International version of NEMA IEC would most likely cover devices made for use in Egypt. I'm not sure what organization or governing body would address the installation there.

Q:Hello all!I know this is a crazy ideaBut I wanna try and build a mini automobile where a person could travel here and there :D I've already planned this but what are the basic requirements I need to engage in this project? I mean apart from the basic structure of the system, what are the main electronic devices and mechanical equipment I need to engage in this? I haven't done anything like this before but I think I have adequate experience. If someone could explain the basic concepts to build a mini automobile with the requirements I would be very grateful :)Thank you: i'll tell you my Electrical point of view, you need to calculate the maximum load, and speed and choose the rating of the DC motor, and of course you need to design a driving circuit to control the speed of the motor, u need a gear to reduce the speed of the motor and get higher torque, that's so difficult for you look for something easier :P

Q:Context:Provide rated electrical equipment where combustible dust is present.: Certified to a set of specifications or standard.
