Description / Abstract:

This Standard specifies the portable insulation resistance testers with a rated measuring voltage not exceeding 1000 V incorporating batteries therein to be used for the following a) to c) as the target of measurement

a) Insulation measurement of low voltage distribution line which is the insulation measurement of lines and devices in a distribution system not exceeding a.c. 1 000 V and d.c. 1 500 V where the power supply is interrupted

b) Insulation measurement of device, appliance, components, etc.

c) Insulation measurement of high-voltage equipment

NOTE: The International Standards corresponding to this Standard and the symbol of degree of correspondence are as follows:

IEC 61557-1: 2007 Electrical safety in low voltage distribution systems up to 1 000 V a.c. and 1 500 V d.c.-Equipment for testing, measuring or monitoring of protective measures-Part 1: General requirements

IEC 61557-2: 2007 Electrical safety in low voltage distribution systems up to 1 000 V a.c. and 1 500 V d.c.-Equipment for testing, measuring or monitoring of protective measures-Part 2: Insulation resistance (Overall evaluation: MOD)

In addition, symbols which denote the degree of correspondence in the contents between the relevant International Standards and JIS are IDT (identical), MOD (modified), and NEQ (not equivalent) according to ISO/ IEC Guide 21-1.
