Therefore, the following duties for the metal-oxide surge arresters without gaps and the metal-oxide surge arresters with internal series gap to operate due to slow front overvoltages caused by switching or system faults are not considered for this standard:switching impulse sparkover voltage;residual voltage at steep current and switching current impulse;residual voltage at steep current and switching current impulse;thermal stability;long-duration current impulse withstand duty;power-frequency voltage versus time characteristics of an arrester;disconnector test;aging duties by power-frequency voltage.Considering the particular design concept and the special application on overhead transmission and distribution lines, some unique requirements and tests are introduced, such as verification test for coordination between insulator and EGLA withstand, follow current interrupting test, mechanical load tests etc.
Insulation Coordination Standards60071-1Insulation co-ordination - Part 1: Definitions, principles and rulesThis part of IEC 60071 applies to three-phase a.c. systems having a highest voltage for equipment above 1 kV. It specifies the procedure for the selection of the rated withstand voltages for the phase-to-earth, phase-to-phase and longitudinal insulation of the equipment and the installations of these systems. It also gives the lists of the standard withstand voltages from which the rated withstand voltages should be selected. This standard recommends that the selected withstand voltages should be associated with the highest voltage for equipment. This association is for insulation co-ordination purposes only. The requirements for human safety are not covered by this standard.

These are surge arresters consisting of one or more non-linear resistors which may be in series with single or multiple spark gaps.Low-voltage limiters are covered under Clause 7. These are protective devices mainly used in fixed installations of d.c. traction systems to connect certain portions of the circuit, when, owing to an abnormal situation, the voltage across the device exceeds a predetermined limited value. They may be associated with other devices such as contactors for self-restoring arrangements. They are not used in general to provide surge protection.The following are the main uses of Low-Voltage Limiters (LVL):connection to the rail of metallic masses;protection of rail circuits;earthing of rails in the substation;protection of cathodic circuits;protection of cable shields.
