What Is Dielectric Testing?

Dielectric testing is a evaluation process performed by applying a voltage to an electrical component that exceeds its normal operating voltage. The purpose of the test is to determine if a component’s insulation is adequate enough to protect the user from electric shock. This testing procedure is typically performed on electrical components, such as circuit boards, appliances, cables, transformers, and electric motors. The manufacturer of an electrical component typically conducts the testing at the end of the production process, using a special device known as a dielectric tester.
Almost all electrical components leak a certain amount of electrical current due to a variety of different factors. This very small amount of current is considered to be safe for users, but under certain conditions, the insulating materials or mechanisms can breakdown and allow dangerous amounts to come into contact with the user. This type of insulation failure can sometimes cause serious injury or death. Dielectric testing is necessary to ensure that the insulating mechanism of an electrical component will withstand voltage variations under normal operating conditions.
The most common type of testing is the dielectric breakdown test. In this procedure, a high voltage electrical current is applied to the component. The dielectric tester monitors the amount of current leakage during the test to determine if the insulation has failed. The high voltage current continues to be applied to the device until the insulation fails or the time limit of the procedure has been reached. If the insulating mechanism does not fail, the product is usually considered to be safe for use. Electrical components that fail during dielectric testing are typically redesigned in order to meet safety requirements.
In addition to the dielectric breakdown test, a procedure known as a dielectric withstand test is also conducted to determine if defects have occurred during the manufacturing process. Electrical components sometimes contain small flaws, such as gaps or spaces that can create an electrical short circuit during the normal operation of a device. Dirt, humidity, environmental contaminates, and vibration can combine to produce an electrical shock hazard if these manufacturing flaws go undetected prior to consumer use. In this procedure, electrical current is supplied to the component at normal operating voltage. A dielectric tester is attached to the component to monitor the amount of current leakage present. If the leakage levels are within an acceptable range, the component is approved for use.

What is power factor?

Power factor is the relationship between working (active) power and total power consumed (apparent power). Essentially, power factor is a measurement of how effectively electrical power is being used. The higher the power factor, the more effectively electrical power is being used. A distribution system's operating power is composed of two parts: Active (working) power and reactive (non-working magnetizing) power. The ACTIVE power performs the useful work - the REACTIVE power does not. It's only function is to develop magnetic fields required by inductive devices.

Why improve low power factor?

Low power factor means poor electrical efficiency. The lower the power factor, the higher the apparent power drawn from the distribution network.
When low power factor is not corrected, the utility must provide the nonworking reactive power in addition to the working active power. This results in the use of larger generators, transformers, bus bars, wires, and other distribution system devices that otherwise would not be necessary.
As the utility's capital expenditures and operating costs are going to be higher, they are going to pass these higher expenses to industrial users in the form of power factor penalties and higher utility bills.

 

 

ABB's Power Factor Correction Capacitors Solve the Problem

Solve low power factor problems by adding power factor correction capacitors to your electrical network. As illustrated below, power factor correction capacitors work as reactive current generators "providing" needed reactive power (kvar) to the power supply. By supplying their own source of reactive power, the industrial user frees the utility from having to supply it; therefore, the total amount of apparent power (kVA) supplied by the utility will be less. Power factor correction capacitors reduce the total current drawn from the distribution system and subsequently increase system capacity.

Who can benefit?

Many industrial and commercial applications can benefit from improving power factor levels. These include: manufacturers, hospitals, shopping malls, office building & institutions, pulp & paper mills, saw mills, textile mills, printing plants, Dlastic manufacturers. etc.

How much can be saved?

In the following example, if power factor correction is applied to the electrical network, increasing power factor to 90%, the potential annual savings on utility bills would be $4,322.23, or an average of $360 per month, a savings of up to 15%!

what is the role of reactive power in power generation?why we have maintain it.

 Electrical machines work on the principle of conversion of
electromagnetic energy.A part of input energy is consumed 
for creating and maintaining the magneticfield.This part of
the input energy cannot be converted into active energy and
is returned to the electrical network on removal of the
magnetic field. This power is known as “reactive” power Q.
The Q Power flows back and forth, causing 90º Out of phase
shift between the current and voltage waveform.This
Reactive Power has one half of the Power In the positive
area and the other half in the negative area.
Unlike true power, reactive power is not useful power
because it is stored in the circuit itself.
This power is stored by
1)Inductors,
Because they expand and collapse their magnetic
fields in an attempt to keep current constant,
2) Capacitors, Because they charge and discharge in an
attempt to keep voltage constant. 

Calculator and E+ meaning

Calculators and e+ The e stands for Exponent, which means the number of tens you multiply a number by. For example, if I square 123456789, I get 1.524157875019e+16, which means that the answer is 1.524157875019 times 10 raised to the sixteenth power (that is, multiplied by 10 sixteen times). To write it as a regular number, you can just move the decimal point to the right sixteen places, since multiplying by ten moves the decimal point one place to the right: 1.524157875019e+16 = 15,241,578,750,190,000 That's over 15 quadrillion. You can also have a negative exponent, which means you have to move the decimal point to the left. For example, if I divide 1 by 123456789, I get: 8.10000007371e-9 = 0.00000000810000007371 In both cases, you can see that the reason for using the "e" notation is to be able to show a number that would have too many digits to display if they wrote it all out.

SCR or Thyristor both are same

A silicon-controlled rectifier (or semiconductor-controlled rectifier) is a four-layer solid state current controlling device.

• ·         The name "silicon controlled rectifier" or SCR is General Electric's trade name for a type of thyristor.

The SCR was developed by a team of power engineers led by Robert N. Hall and commercialized by Frank W. "Bill" Gutzwiller in 1957.

Modes of operation

This device is generally used in switching applications. In the normal "off" state, the device restricts current to the leakage current. When the gate-to-cathode voltage exceeds a certain threshold, the device turns "on" and conducts current. The device will remain in the "on" state even after gate current is removed so long as current through the device remains above the holding current. Once current falls below the holding current for an appropriate period of time, the device will switch "off". If the gate is pulsed and the current through the device is below the latching current, the device will remain in the "off" state.

If the applied voltage increases rapidly enough, capacitive coupling may induce enough charge into the gate to trigger the device into the "on" state; this is referred to as "dv/dt triggering." This is usually prevented by limiting the rate of voltage rise across the device, perhaps by using a snubber. "dv/dt triggering" may not switch the SCR into full conduction rapidly, and the partially triggered SCR may dissipate more power than is usual, possibly harming the device.

SCRs can also be triggered by increasing the forward voltage beyond their rated breakdown voltage (also called as break over voltage), but again, this does not rapidly switch the entire device into conduction and so may be harmful so this mode of operation is also usually avoided. Also, the actual breakdown voltage may be substantially higher than the rated breakdown voltage, so the exact trigger point will vary from device to device.

Reverse Bias

SCR are available with or without reverse blocking capability. Reverse blocking capability adds to the forward voltage drop because of the need to have a long, low doped P1 region. Usually, the reverse blocking voltage rating and forward blocking voltage rating are the same. The typical application for reverse blocking SCR is in current source inverters.

SCR incapable of blocking reverse voltage are known as asymmetrical SCR, abbreviated ASCR. They typically have a reverse breakdown rating in the 10's of volts. ASCR are used where either a reverse conducting diode is applied in parallel (for example, in voltage source inverters) or where reverse voltage would never occur (for example, in switching power supplies or DC traction choppers).

Application of SCRs

SCRs are mainly used in devices where the control of high power, possibly coupled with high voltage, is demanded. Their operation makes them suitable for use in medium to high-voltage AC power control applications, such as lamp dimming, regulators and motor control.
