Suntan Dissemination of Varistor Pitch Testing

---All Kinds of Capacitors

Generally speaking, the capacitor pitch is the straight line distance from one lead to another. However, for varistor (Suntan TSV series), Y1/Y2 safety standard recognized capacitor (TS22), the pitch need to be specially tested because the lead is not symmetrical considering the capacitor body. We thought it was a common sense but obviously some of our customers did not think so. Anyway, for avoiding any future misunderstanding, here we confirm the correct testing way as below pictures showing, which is the industry standard applying to above mentioned capacitors.

Zno varistor (Carbon resistor) :  also known as "surge absorber" by the usage or Metal Oxide Varistor (MOV),  is a voltage current symmetrical characteristic of resistor voltage attribute, its main design is used to protect all the electronic products or components from the switch or lightning induced by a surge of impact, and the characteristics of nonlinear index, that is similar to that of a diode. In contrast to a diode however, it has the same characteristic for both directions of traversing current. At low voltage it has a high electrical resistance which decreases as the voltage is raised. 
 
Features: fast reaction time, low leakage current, the superior voltage ratio, wide voltage and energy than, low standby power and no subsequent current, highly efficient surge current capacity, suppress voltage characteristic of stable performance.
 
In low voltage, varistor relative to the protected in terms of electronic components, has the very high impedance primes megohm, and will not change the design circuit characteristics, but when the instant surge voltage (over the collapse of varistor voltage), the impedance of the varistor will become low (only a few ohms), and cause the short circuit, in other words the electronic products or components which are protected.
 
Main use: lightning protection, over voltage protection. Such as power transformer at the service entrance putting into the zinc oxide lightning arrester can effective lightning protection, electronic equipment in power grid power input putting into the varistor, if the grid voltage rise the varistor will short out and fuse will also be disconnected at the same time, effectively stop over voltage into the circuit board. 
 
Suntan Produce two types of varistor, they are Dipped Varistor TSV and SMD Varistor TSVC. For more datails, please check at : http://www.suntan.com.hk/Varistor/

Suntan Metal Oxide Varistor Function---Surge Protection

October 10, 2012 Views
Comments 0

Suntan Technology Company Limited
----All Kinds of Capacitors
 
Varistors are voltage-controlled resistors. They are common in outlet strips, Uninterruptible Power Supplies (UPS) and on electrical power lines.
 
Other names for varistors include current suppressors, lightning arrestors, surge arrestors and surge suppressors.
 
In the most common type of surge protector, a component called a metal oxide varistor, or MOV, diverts the extra voltage.  an MOV forms a connection between the hot power line and the grounding line.

What is a metal oxide varistor? 
A metal oxide varistor is a voltage-dependent, semiconductor-based, variable resistor.  Electrically, it appears as an open circuit across a power line until its voltage threshold is reached.  When this occurs, the varistor will instantaneously change from a high resistance mode (open circuit) to a low resistance mode (short circuit), thus conducting currents through it. Once the overvoltage event has passed and the voltage returns to below the threshold level of the varistor, it will return to an open circuit again until the next overvoltage event that exceeds its threshold occurs.
 
What is a surge protector?
A surge protector is an electronic device that limits transient overvoltages to a safe level, thus protecting equipment from damage or disruption. A surge protector may also be expressed using the following terms: SPD (Surge Protective Device), TVSS (Transient Voltage Surge Suppressor). An arrestor (used by utility companies and communication companies) is also a surge protector, but is typically employed in a different part of the electrical system than a surge protector.
 
Metal oxide varistors(MOVs) are among the most common devices used to provide surge protection for electrical and electronic circuits.
 
An MOV has three parts: a piece of metal oxide material in the middle, joined to the power and grounding line by two semiconductors.
 
These semiconductors have a variable resistance that is dependent on voltage. When voltage is below a certain level, the electrons in the semiconductors flow in such a way as to create a very high resistance. When the voltage exceeds that level, the electrons behave differently, creating a much lower resistance. When the voltage is correct, an MOV does nothing. When voltage is too high, an MOV can conduct a lot of current to eliminate the extra voltage.
 
As soon as the extra current is diverted into the MOV and to ground, the voltage in the hot line returns to a normal level, so the MOV's resistance shoots up again. In this way, the MOV only diverts the surge current, while allowing the standard current to continue powering whatever machines are connected to the surge protector. Metaphorically speaking, the MOV acts as a pressure-sensitive valve that only opens when there is too much pressure.
