Surge Arresters

Kingtronics sell 2-Electrode arresters and 3-Electrode arresters. Surge arresters are designed to protect electrical equipment from damaging effects of spikes and transients caused by lightning, utility switching, isolation arcing, electrical motor cycling, or any other sudden change in electrical power flow on incoming AC power lines. And these devices also provide ideal protection for outdoor lighting and pole lamps, panel boards, workshops, refrigeration systems, electric motors and controls, heat pumps and air conditioning equipment, and many other electrical devices. Present customers include many OEM's, as well as distributors of telecommunications, motor drives, utilities, and other equipment or systems.

About Surge Arresters

Excessive voltages and the resulting surge currents can damage or even destroy communications equipment, data transmission and energy supply systems. Injury to human beings cannot always be excluded either.

Surge arresters operate on the gas-physical principle of the highly effective arc discharge. Electrically, surge arresters act as voltage-dependent switches. As soon as the voltage applied to the arrester exceeds the spark-over voltage, an arc is formed in the hermetically sealed discharge region within nanoseconds. The high surge current handling capability and the arc voltage, which is almost independend of the current, short-circuit the overvoltage. When the discharge has died down, the arrester extinguishes and the internal resistance immediately returns to values of several 100 MΩ.

Cautions and Warnings when use Surge Arresters

  • The surge arrester must be selected so that the maximum expected follow current can be quenched.
  • The follow current must be limited so that the arrester can be properly extinguished when the surge has decayed. The arrester might otherwise heat up and ignite adjacent components.
  • The short-circuit spring does not trigger untill 140,200, 260 and 300℃ is reached depending on the sensor material. Care must be taken to limit the thermal radiation onto adjacent parts to safe values.
  • Depending on the incorporation position, the surge arrester may have to be additionally secured by mechanical means.
  • If the contacts of the surge arrester are defective, current stress can lead to the formation of sparks and loud noises (bang).
  • Surge arresters must not be operated directly in power supply networks.
  • Surge arresters may become hot in the event of longer periods of current stress (danger of burning).
  • Surge arresters and switching spark gaps may be used only within their specified values. In the event of overload, the lead contacts may fail or the component may be destroyed.
  • Damaged surge arresters must not be re-used.
  • Surge arresters with triggered short-circuit mechanisms must not be re-used.
  • Ensure appropriate handling of components passed on for subsequent industrial processing.
  • Operatives who suffer from excessive sensitivity to metals must wear light gloves when performing manual placement operations.
  • Surge arresters should be disposed of in the same way as industrial waste resembling household refuse. In individual cases, any legal stipulations departing from this rule must be observed.
