6.5.1.2.4 SOLID INSULATION

Delete the entire subclause including Table 4, Table 5, Figure 15, Figure 16 and Figure 17.

Add the following new subclause:
6.5.1.3 Solid insulation

The term “solid insulation” is used to describe many different types of construction, including

monolithic blocks of insulating material and insulation subsystems composed of multiple

insulating materials, organized in layers or otherwise.

The electric strength of a thickness of solid insulation is considerably greater than that of the

same thickness of air. The insulating distances through solid insulation are therefore typically

smaller than the distances through air. As a result, electric fields in solid insulation are

typically higher, and often are less homogeneous.

Solid insulation material may contain gaps or voids. When a solid insulation system is

constructed from layers of solid materials, there are also likely to be gaps or voids between

layers. These voids will perturb the electric field so that a disproportionately large part of the

electric field is located in the void, potentially causing ionization within the void, resulting in

partial discharge. These partial discharges will influence the adjacent solid insulation and may

reduce its service life.

Solid insulation is not a renewable medium: damage is cumulative over the life of the

equipment. Solid insulation is also subject to ageing and to degradation from repeated high

voltage testing.
Conformity is checked as specified in 6.5.2.5 and 6.5.2.6.
6.5.2.2 CLEARANCES for probe assemblies of MEASUREMENT CATEGORIES II, III and IV
Replace the existing Table 6 with the following:

Replace, in the conformity statement, the word “clearance” with “CLEARANCE” (in SMALL CAPS).

6.5.2.3.1 General

Replace, in the second paragraph, the words “required clearance” with “required CLEARANCE”.

Add the following two new subclauses, Table 4, Table 5, Table 14, Figure 15, Figure 16 and

Figure 17:
6.5.2.5 Solid insulation of probe assemblies RATED for MEASUREMENT CATEGORIES
6.5.2.5.1 General

6.5.2.5.1.1 Solid insulation of probe assemblies RATED for MEASUREMENT CATEGORIES shall

withstand the electrical and mechanical stresses that may occur in NORMAL USE and in all

RATED environmental conditions (see 1.4) during the intended life of the probe assembly.

The manufacturer should take the expected life of the probe assembly into account when

selecting insulating materials.
Conformity is checked by both of the following tests:

a) the a.c. voltage test of 6.6.5.1 with a duration of at least 5 s using the applicable test

voltage of Table 4 or the impulse voltage test of 6.6.5.3 using the applicable test voltage

of Table 14;

b) the a.c. voltage test of 6.6.5.1 or if stressed only by d.c., the d.c. voltage test of 6.6.5.2,

with a duration of at least 1 min using the test voltage determined by 6.5.2.5.1.2.

NOTE Test a) checks the effects of transient overvoltages, while test b) checks the effects of long-term stress of

solid insulation.
