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:i am attending college in the fall, actually school starts on the 21st, and my major will be in electrical engineering, i was just fishing around and wondered if anyone could give me, in a nutshell, the basics of this field. since i have already chosen this as my major I do know a little, enough to choose it as my major. i just wanted to know what I might not already know. Give the names of specific jobs that would be of interest after graduation also, if you know any. Thanks!
- Sky is the limit! Beside all the obvious electrical engineering jobs such as circuit designer (both digital or analog), system engineer, semiconductor process or equipment engineer, power engineer, communication engineer, product engineer, device engineer, QC engineer, field service engineer, etc. You can be an astronaut, mission control engineer (for NASA), technical marketing or sales engineer (with MBA), apply for medical school, and God forbids be a professor in engineering (with PhD), Simply too many to list.
- Q:I am just a few classes away from getting my Associates in Electrical Engineering. I currently have a Diploma in Industrial Electricity and have been working in industrial maintenance for 12 yrs. and am currently an electrical technician (10 yrs. multi-skilled and the last 2 yrs. strictly electrical due to a job change). I have returned to school to get my AAS in EE, so I would really like to know what possibilities I could expect.
- You can get a job as an electronic engineering technicians. You help design, develop, test, and manufacture electrical and electronic equipment such as communication equipment, medical monitoring devices, navigational equipment, and computers. You may work in product evaluation and testing, using measuring and diagnostic devices to adjust, test, and repair equipment. Median annual wages of wage and salary electrical and electronic engineering technicians were $53,240 in May 2008. The middle 50 percent earned between $41,550 and $64,120.

- Q:for a store of electrical equipments, I want to create a database for it, what is the data that I should maintain in this database (the names of the columns)?
- You need multiple tables. Using int() auto_increment primary keys for linking each section of data you want something like : stock_codes ( id int(6) primary key auto_increment, stock_code varchar(45) unique key, stock_description varchar(45), stock_qty int(6), suppler_id int(6) ) stock_movement ( id int(6) primary key auto_increment, in_date date, out_date date, moved_qty int(6), stock_id int(6), ) It helps to have tables of suppliers details, client details, sales person details, department details etc. If items have possible alternative suppliers you dump the supplier_id from the stock codes and use a link table for the stock id and supplier id to identify each inward transaction. Add tables for any additional information using links from the other tables to co-ordinate the data.

- 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 doing a project on electronic baton.I want it to look exactly like baton used by professional orchestra conductor.I stored the electronic components inside the handle of the baton.The problem is the space is very limited.The maximum diameter of the handle only about 18 mm.I need to choose a battery that also stored inside the handle.I want the battery that could work for long time.However what I can see the coin battery that is small only have small energy in it.It will only last for less than 1 hour.It is not good for new product.What can I do to maximize amount of energy so baton can work for longer time? ideally 10+hours or minimum of 5 hours and can fit inside small handle.I dont want to use external power cable.Hope you guys can help me.Really appreciated all of your helps.
- what i can't believe is that you've found a gyroscope, microcontroller, and bluetooth circuitry to fit in there - please tell us the manufacturer and part numbers for your parts - i would love a microcontroller that small - not to mention bluetooth
- Q:electrical safety product
- It is very similar to a surge protector in that it senses an sudden increase in voltage and/or current and quickly diverts the circuit to ground or isolates the attached devices.
- Q:i am instrument electrical eng.student and i am about to take 2 of the 4 subject for electives, here the subject:1)process control2)automation and robotic3)measurement and instrumentation4)control system 3i am thinking to involve in maintainance,oil and gas or maybe aircraft maintainance.after grad.what is the subject is suitable and what is the subject advantage and disadvantage. i want get some advice before make the decision.tq
- Well. it is very good major Oil and Gas companies need ur major since the instrumentation is controlling the whole units. Huge Essential System and very critical in any refinery such as: DCS : Digital Control Center. ESD: Emergency Shutdown. UPS: Uninterrupted Power Supply ( Electrical Equipment feeds instrument load) I think u have a bright future with this discipline if you have interests . And regarding these Subjects, i dont know much about control All the best
