Bringing the benefits of 15 kV DC insulation resistance testing to challenging environments such as HV transmission and distribution substations, Megger’s new S1-1568 test sets combine class-leading noise rejection of 8 mA – twice that of most comparable instruments – with user selectable software filtering and the ability to make accurate and dependable measurements up to 35 T?.
The 15 kV capability of the new S1-1568 insulation resistance test sets means that they can be used to demonstrate compliance with the growing number of standards that specify this test voltage. These include, for example, NETA MTS-1997 Table 10.1, applicable to maximum voltage rating of equipment, NETA ATS 2007 Section 7.15.1 for medium-voltage motors, and IEC 60229 2007 for electric cables with a special protective function.
