Abstract

PURPOSE:To enable the accurate detection of a faulty insulator by measuring the insulation resistance value of each insulator constituting an insulator string which is provided in the fore end of an insulating rod. CONSTITUTION:The insulation resistance value of a separate insulator 30 is measured by a measuring element 8 by operating an insulating rod 1. This value is transmitted to a quality determining element 12 on the operator side, and after all measured values are taken in a storage circuit 13, a faulty insulator is specified in an arithmetic circuit 14 by means of the relative comparison of the insulation resistance values. Although the absolute value of the insulation resistance value of the insulator 30 is varied to a large extent according to the conditions of the surroundings, the nonuniformity in the insulation resistance value of the separate insulator under the same conditions of the surroundings is small in a sound insulator string. Therefore the faulty insulator can be specified by the relative comparison irrespective of a change in the conditions of the surroundings.
