Product Description:


It is used in the AC power distribution system terminal with the 1 kV voltage or more to increase power factor,to reduce ciruit loss,to improve the output of the transformer and to make the motor economically operated.It is used paralleled with the motor and the inductive load to automatically tracking compensate to the frequency factor.TBBW2 merged measurement and Compensation funceions into 1,it is the best choice for low-voltage side compensation of tranformers.
Operating standard:IEC439,GB7251-97,JB7113-93.

Main features

a、Novel in structure,light in weight.
b、Applies the intelligent reactive compensation controller, has complete functions and good performance.The compensation type can be transformed at liberty between the automate and the manual.

Q:I have no headlights,why?
Verify there is battery voltage present at the switch on the Red/White wire. If not check fuses. If ok check for battery voltage coming out of the headlight switch on the Light Green wire in the headlight position. If no voltage on LG wire , replace headlamp switch. .
Q:96 Chrysler Concord fuse?
I know you said that you checked the fuses ,but did you check both fuse boxes .You should have one under the dash and another one under the hood. It sure sound like you have a blown fuse to me.
Q:What could possibly be wrong with my dc bench power supply?
Fuses generally protect against fire rather than damage. So even if you replace the blown fuse, the power supply may still be broken.
Q:Fuses on an 05 750 shadow?
I'm thining you still have a bare wire grounding out somewhere, hard to find to :(
Q:During the formation of a star, two reactions take place.?
The mass you use in Emc^2 is the difference in mass between the fused atom and it's components. For example in (A) your mass (that is converted to energy) is 3.01550 - (2.01355+1.00728) 0 If you want to know why then look up mass defect
Q:Speaker drops out after replacing blown fuse, how do I fix it permanently?
You obviously have a loose connection--speaker drivers very rarely have an intermittent problem. I would check the fuse-holder. Either the spring at one end is not under enough pressure when the fuse is in, or perhaps you replaced the original fuse with one slightly shorter. Unfortunately it has been many years since I have seen a DM220, and I don't remember the type of fuse or fuse-holder that it has. I would swap fuses with the other speaker, and see if the problem moves: I HAVE seen defective, intermittent fuses!
Q:How much current for a 10 HP motor at 480v?
You are about correct for a three-phase motor. I'm reading 14 amps, but this depends on the type of motor and varies. You always figure amps per phase in circuits. Breaker ampere trip ratings are also listed per phase. Motor inrush can be four to seven times full load amp rating for motors (depending on the type of motor). This value is often referred to as locked rotor amps. If you size a breaker or fuse as you would another type of circuit, such as a lighting circuit, you will continually trip a breaker or clear a fuse. If you are in the U.S. and need to provide this per NEC, then the requirement is, you can select a circuit breaker up to 250% of the full load amps. If the motor is protected by fuses, you are allowed a fuse rating up to 175% of the full load motor rating. Assuming 14 amps full load, the apparent breaker rating would be 35 amps. You can select a 40 amp breaker since it is the next commonly available breaker rating above 35 amps. Feeder circuit conductors for the motor need to be sized 125% of the full load rating per the NEC. 14 x 125% 17.5; so #12 AWG (which is rated up to 20 amps) circuit conductors are minimum.
Q:van wont shift out of park, brake lights are off but so are 10 other electrical components?
Your brake lights not working is the reason it won't come out of park. Some of the newer vehicles have more than one fuse box. Mine has one under the back seat and one under the hood. The owners manual is the first place to start. Make sure ALL the fuses are good. You'll need a test light, check for power at your brake light switch, located on the brake pedal under the dash. Then check to see if you have power at the other end of the switch when the pedal is depressed. A lot of times, it is this switch that goes bad or just gets knocked around. If you have power on both sides of this switch, then you move on to the bitsy solenoid. I'd need more information to tell you where it is on your van, but try checking the brake light switch first. Good luck!
Q:how to turn off the air bags light and seat belt light on a 2003 jeep grand cherokee larado?
you will need to take your car to the main dealer or someone with a code reader and they will turn your warning lights out. they probably came on because you pulled the fuse or disconnected an airbag wire while the ignition was turned on the dealer will probably read the code first and inform you of a probable fault. when an electrical component on a vehicle is disconnected while the ignition is turned on the ECU will will detect a (fault) ie power failure to the individual item that has been disconnected.
Q:Help with physics homework?
OK, this question doesn't make sense, for two reasons: 1.) Colors, by definition, are at different wavelengths. If the beam has 2 color components, each component would have it's own wavelength. 2.) Your question at the end isn't a proper sentence, and is leaving a necessary part out.
