How does a Transient Voltage Surge Suppressor work?

How does a Transient Voltage Surge Suppressor work?

A TVSS or Transient Voltage Surge Suppressor protects sensitive electronics from short duration, extreme voltage spikes. This protection is accomplished by clamping the voltage to a safe level before the equipment is destroyed. The excess current is then diverted to the ground.

What is surge and transient?

In general a surge is a transient wave of current, voltage or power in an electric circuit. Surges, or transients, are brief overvoltage spikes or disturbances on a power waveform that can damage, degrade, or destroy electronic equipment within any home, commercial building, industrial, or manufacturing facility.

Is there a difference between a surge protector and a surge suppressor?

Surge suppressors differ from surge protectors in that surge protectors are basically just extension cords with minimal built-in protection (fuses, etc.). Quality surge suppressors, on the other hand, should be designed to clamp the voltage before any damage is done to the computer circuitry.

What is ul1449?

UL 1449 is the Underwriters Laboratories Safety Standard for Surge Protective Devices (SPD). Surges are rapid increases in voltage and current that can occur on AC or DC power circuits that can damage equipment attached to these circuits. The surge voltage drives high current down the power line.

What is Transient Voltage?

A transient voltage is a temporary unwanted voltage in an electrical circuit that range from a few volts to several thousand volts and last micro seconds up to a few milliseconds.

What does a transient suppressor do?

Transient Voltage Suppressors (TVS’s) are devices used to protect vulnerable circuits from electrical overstress such as that caused by electrostatic discharge, inductive load switching and induced lightning. In a circuit, the TVS should be “invisible” until a transient appears.

What is Transient voltage?

What are surge suppressors used for?

A surge suppressor (sometimes optimistically called a “surge protector”) is a device inserted in the alternating current ( AC ) utility line and/or telephone line to prevent damage to electronic equipment from voltage “spikes” called transients.

What does surge suppressor do?

When would you use a surge suppressor?

It’s a good idea to use surge protectors for other high-end electronic equipment, such as entertainment center components. A surge protector will generally extend the life of these devices, and there’s always a chance that a big power surge will causes severe damage.

What UL 1363?

UL 1363, 5th Edition, June 12, 2018 – UL Standard for Safety Relocatable Power Taps. These requirements cover indoor use cord and plug connected, relocatable power taps (RPT) rated 250 V AC or less and 20 Amperes or less.

What is UL surge protection?

UL 1449 Voltage Protection Rating (VPR) is a measure of the surge protector’s “let-through” voltage, which is the maximum voltage a surge protector will let through to connected devices. The lower the VPR number, the better the protection. A lower SVR number usually indicates better protection.
