Static electricity The phenomenon of static electricity requires a separation of positive and negative charges. When two materials are in contact, electrons may move from one material to the other, which leaves an excess of positive charge on one material, and an equal negative charge on the other. When the materials are separated they retain this charge imbalance.

Basics of Static Electricity Static electricity is the accumulation of electrical charges on the surface of a material, usually an insulator or non-conductor of electricity. It is called static because there is no current flowing, as there is in alternating current (AC) or direct current (DC) electricity.tatic electricity is usually caused when certain materials are rubbed against each other—like wool on plastic or the soles of your shoes on the carpet. It is also caused when materials are pressed against each other and pulled apart.

Basic Circuit Function The OFF-NONE-(ON) or OFF-(ON) circuit is a momentary, single throw, two-position switch circuit. In general, for basic unlighted single pole switches, the momentary ON position closes the circuit at switch terminals 1 & 2. For basic unlighted double pole switches, the circuit is closed at terminals 1 & 2 and 4 & 5.

- The circuit breaker. The circuit breaker does the same job as the fuse, but works in a different way. A spring-loaded push switch is held in the closed position by a spring-loaded soft iron bolt. An electromagnet is arranged so that it can pull the bolt away from the switch.

ported vaccum switch,what purpose do it serve. now when that switch goes bad does it make the car run rough at a idle. Often this switch will have manifiold and ported vacuum coming to it from the carburetor or intake manifold. If it goes bad the manifold vacuum will reach the componet at idle and possibley change the idle Characteristics of the engine. follow the vacuum hoses to find the component it controls. with the engine idling, disconnect the vacuum hose at the componet and check to see if vacuum is present. If so and the engine hasn't reached normal operation temp. the vacuum switch is bad.

Switched-mode power supply 1 By switching the bipolar switch when the voltage is at a minimum (in the valley) to minimize the hard switching effect that causes EMI. 2  By switching when a valley is detected, rather than at a fixed frequency, introduces a natural frequency jitter that spreads the RF emissions spectrum and reduces overall EMI.

What is a Power Supply Voltage Switch? The power supply voltage switch, sometimes called the voltage selector switch, is a small switch located on the back of most desktop computer power supply units (PSUs) This small switch is used to set the input voltage to the power supply to either 110v/115v or 220v/230v. In other words, it's telling the power supply how much power is coming from the power source.

Basics of Static Electricity Static electricity is the accumulation of electrical charges on the surface of a material, usually an insulator or non-conductor of electricity. It is called static because there is no current flowing, as there is in alternating current (AC) or direct current (DC) electricity.tatic electricity is usually created when materials are pulled apart or rubbed together, causing positive (+) charges to collect on one material and negative (−) charges on the other surface. Results from static electricity may be sparks, shocks or materials clinging together.

Transfer switch Intelligent transfer switch. A transfer switch is an electrical switch that switches a load between two sources. Some transfer switches are manual, in that an operator effects the transfer by throwing a switch, while others are automatic and switch when they sense one of the sources has lost or gained power.

- What is a Manual Hard Bypass Switch and why are they necessary?UPS installations often include a manual wrap-around hard bypass switch, also referred to as maintenance bypass switch, or MBS. The manual bypass switch allows the UPS to be de-energized without interrupting power to the critical load. The manual bypass switch provides a safe easy means for a trained service technician to perform routine maintenance, inspections and repairs to the UPS.

- 1 UNDERSTANDING SONET UPSRs. 2  A major advantage of SONET networks is their standardized APS (automatic protection switching) schemes. SONET systems can be configured as point to point terminals, linear add-drop chains and rings. 3  UPSR. To understand how the UPSR works refer to figure 1 which depicts a four node ring. Each node on this ring is connected to its respective adjacent nodes by two fibers, one transmit, and one receive. For purposes of discussion the outer fiber loop is referred to as ring1 and the inner fiber loop is referred to as ring2.

How does a voltage stabilizer work? If the output voltage is not in range a mechanism switches the tap, to change the transformer to move the voltage in acceptable range. It does not give a constant voltage output, but operates the system in a safe voltage range. If any one wants to buy stabilizers online than click here Voltage Stabilizers.

- 3) Connected to the moving contact is a catch that is controlled by your circuit breaker's switch. When the circuit breaker detects unsafe levels of electricity and flips the switch OFF, the catch is triggered, breaking the connection between the moving and stationary contacts and stopping the flow of electricity.

Ensuring Generator and UPS Compatibility When a generator turns on and the switch connecting it to the UPS closes, the immediate application of the load to the generator can cause sudden swings in frequency and voltage. You can usually avoid this situation if the UPS has a walk-in feature.

How does static electricity work? Like charges repel each other (positive to positive or negative to negative). Most of the time positive and negative charges are balanced in an object, which makes that object neutral. Static electricity is the result of an imbalance between negative and positive charges in an object.These charges can build up on the surface of an object until they find a way to be released or discharged.One way to discharge them is through a circuit.tatic electricity is the result of an imbalance between negative and positive charges in an object.

Transistors Electrons are pulled from the emitter into the base—and then from the base into the collector. And the transistor switches to its on state: The small current that we turn on at the base makes a big current flow between the emitter and the collector.By turning a small input current into a large output current, the transistor acts like an amplifier.But it also acts like a switch at the same time. transistor works when the electrons and the holes start moving across the two junctions between the n-type and p-type silicon. Let's connect the transistor up to some power. Suppose we attach a small positive voltage to the base, make the emitter negatively charged, and make the collector positively charged.

Static synchronous compensator A static VAR compensator can also be used for voltage stability. However, a STATCOM has better characteristics than an SVC. When the system voltage drops sufficiently to force the STATCOM output current to its ceiling, its maximum reactive output current will not be affected by the voltage magnitude.sually a STATCOM is installed to support electricity networks that have a poor power factor and often poor voltage regulation. There are however, other uses, the most common use is for voltage stability.
