Properties of surge arrester.<br/>
Attribute
Public Voltage
  continuousOperatingVoltage
Details:
Notes: Maximum continuous power frequency voltage allowed on the surge arrester.<br/>
Public Boolean
  isPolymer
Details:
Notes: If true, the arrester has a polymer housing, porcelain otherwise.<br/>
Public Voltage
  lightningImpulseDischargeVoltage
Details:
Notes: Residual voltage during an 8x20 microsecond current impulse at the nominal discharge current level.<br/>
Public Integer
  lineDischargeClass
Details:
Notes: Determines the arrester energy discharge capability.  Choices are limited to 0 (none) through 5 (highest) by IEC 60099. Classes 1..3 require a 10-kA nominal discharge current. Classes 4..5 require a 20-kA nominal discharge current. Lower nominal discharge currents must use class 0.<br/>
Public CurrentFlow
  nominalDischargeCurrent
Details:
Notes: The lightning discharge current used to classify the arrester. Choices are limited to 1.5, 2.5, 5, 10, and 20 kA by IEC 60099.<br/>
Public CurrentFlow
  pressureReliefClass
Details:
Notes: Fault current level at which all parts of the failed arrester lie within a circle prescribed by IEC 60099.<br/>
Public Voltage
  ratedVoltage
Details:
Notes: The temporary overvoltage (TOV) level at power frequency that the surge arrester withstands for 10 seconds.<br/>
Public Voltage
  steepFrontDischargeVoltage
Details:
Notes: Residual voltage during a current impulse with front time of 1 microsecond, and magnitude equal to the nominal discharge current level.<br/>
Public Voltage
  switchingImpulseDischargeVoltage
Details:
Notes: Residual voltage during a current impulse with front time of at least 30 microseconds, and magnitude specified in IEC 60099 for the line discharge class. Does not apply to line discharge class 0.<br/>
