Intelligent LV reactive compensation box
1. Purposes and characteristics
LV intelligent reactive compensation box of XBZW type can be installed with the transformer on the same pole or the linepole or the wall, etc. It keeps the priority of power factor on on-load feedpoint by selecting suitable capacity,
LV intelligent reactive compensation box ofXBZW adopts distribution intelligent monitor terminal as the control core, the intelligent monitor terminal adopts full digitized design，AC sampling, man Machine Interface of a large screen LCD of 128*64 lattices, and full metal enclosure design to improve efficiently the index of electromagnetism compatibility.
The installation of it is in accordance with the DIN standard, with the installation of an embedded/wall mounted series, the main board adopts AMT SMT (surface mount technology) equipment with power distribution monitor,reactive power compensation, harmonic analysis, incident record, electrical energy measuring, I/0 interface, and temperature sensor interface. The device provides serial port 1 of RS232/485 and serial port 2 of RS—485, the serial port 2 is a data transmission serial port to mainly support the multi-function electronhour meter. The communication method of serial port 1 supports twisted-pair, coaxialline, data radio and CPRS, which also can be commutated with the cooperation of light MODEM and optical fiber.

3. Function description
This equipment can record once after every 15minute interval, and can save 90 days history records. The record density can be chosen by 15 minute, 30 minute, 45 minute, and 60 minute. For the operation of this equipment, please see the communication rule as a reference.
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 know you need fuses for cars, electrical equipments, etc. I don't get what they are really used for?
- If there occurs a short circuit or an overload beyond the current rating of the fuse, the thing melts inside, breaking the contact, stopping current flow, and sending someone off in search of a new fuse rather than repairing the situation which blew out the last one. Nothing in the fuse breaks, it melts. A fuse is not a mechanical circuit breaker, which is an actual switch actuated either magnetically (in AC circuits) or a bimetallic strip which has the current going through it and gets hot enough on excessive current that it self-bends and breaks the connection temporarily, and can be reset. Once a fuse blows, it's over for that fuse.
- Q: I'm comparing the GP 6500 with 389 cc engine (splash lubrication) to the XG 6500 with a 410 cc industrial engine (oil pump pump lubrication). I would be using it for home emergency use, so I doubt I really need the industrial engine with oil pump. Over 10 years it will probably only get 100 hours on the engine mostly at a consistent 50% load with occasional short term peaks closer to max (toaster, sump pump coffee pot, etc). So I'm leaning towards the cheaper GP. But want to consider the following:Are they both easy to pull start? The biggest engine I pull start is my snowblower with a 250cc OHV Briggs. But when starting only the engine is turned, i.e. it's not engaged to the snowblower yet. The hardest thing I have to start is my power washer with a 160cc OHV Kohler. I think because it's directly connected to the pump which makes it harder to start.Is the XG industrial engine quieter than the GP engine?
- Generac Xp
- Q: Electrical system in a residential building. When we use any equipment on one phase the lights on that phase dim down but and the same time the lights on the second phase become brighter.
- The voltage on loaded phase dips on the account of starting current of equipment. This problem is specifically critical in case of motors. So the dimming brightening happens because of unbalance is 3 phases of the installation. This condition is completely normal keeps happening always.
- Q: a small fire that is at the outlet
- Shut off power at the circuit breaker and the class 'C' (electrical) fire is out. If anything is still burning, it is a Class 'A' (leaves an ash) fire and water will suffice. Baking soda can be used for Class 'B' (burning liquid) fires, but not electrical fires.
- Q: hi guyscan you explain in simple words what is earthing process and how it helps to secure human from detected current.thanks
- Earthing system helping for Human safety to avoid electrocution due to earth leakage.Earth is acting like a Huge conductor because of it minerals Moisture contend (water).If any electrical equipment Insulation failure leakage will be there ,if the same equipment is not Grounded ,there is a possibilitiesof getting electric shock to Human.If the same equipment is Grounded the leakage current will flow to Earth protect from electric shocks Trip the circuit. Pl. check this link for brief idea.
- Q: electrical equipments like resistor,capacitor, transistor, etc
- you have to go to asan you kind find many stores selling them. You just go to asan and ask for anyone there they will tell you the way correctly.
- Q: has to do with electrical control
- It is the National Fire Protection Association standard for electrical safety. Just do a Yahoo search for nfpa 70 and you will find it.
- Q: I am an electronics engg and have four year of exp in marketing .please do let me know the procedure to start such business. i have heard that we need to pay big amount as security to take dealership of any product .please also if some one can tell me the percentage margin left in trading.Is it profitable?? i want to open this company in rajasthan udaipur.
- Check your local news on how the industry is doing. Compare the unemployment and so forth to know if there is enough cash flow going on. Sometimes opening a business [which is risky] can work if you aim at a certain group and you know your audience. Do the investigating.
- Q: Examples include-Unplug your wireless router for 30 seconds and then plug back inUnplug all elerical cords for 45 seconds then plug back inWhy do they recommend a specific amount of time?
- It needs to shut down completly and it takes a few seconds. If you plug it back in too quickly then it acts as if it never was unplugged.
- Q: (1) source would be from a house and another source would be from a battery [and may not always be on but when on should have priority over the house's power].
- What you're describing is called an uninterruptible power supply, or UPS. It allows your normal house electrical to power your equipment and cuts in the batteries when the electric fails. The amout of load and size of batteries will determine how long the UPS can run from the batteries. If you are just going to power your computer, these things can be purchased from most computer stores.
