IEC TS 62993:2017

Tue, 05 Nov 2024 20:14:07 +0000

IEC TS 62993:2017 gives guidance to technical committees which deal with equipment having a rated voltage of more than 1 000 V AC and up to 2 000 V AC, or a rated voltage of more than 1 500 V DC and up to 3 000 V DC. Rated voltages up to 1 000 V AC and 1 500 V DC, as well as higher or lower internal voltages, are covered by IEC 60664-1.
This document applies to equipment for use up to 2 000 m above sea level, and provides guidance for use at higher altitudes.
This document gives guidance for clearances, creepage distances and solid insulation for equipment to achieve safety. It includes methods of electric testing.

IEC TS 62332-1:2011

Tue, 05 Nov 2024 20:11:45 +0000

IEC/TS 62332-1:2011(E) is applicable to EIS containing solid and liquid components where the thermal stress is the dominant ageing factor, without restriction to voltage class. This part specifies a dual-temperature test procedure for the thermal evaluation and qualification of electrical insulation systems (EIS). The following significant technical changes with respect to the previous edition have been made – Modifications have been made based on an extensive test series conducted using this methodology given in the first edition. This included updating expected times and tempertatures to use in order to obtain useful results, as well as making the range of equipment covered broader. The method can now cover electrotechnical devices using different sealing systems, as well as devices using enamel covered wires.

IEC TS 62101:2005

Tue, 05 Nov 2024 20:10:56 +0000

Applies to electrical insulation systems, specifies a short-time thermal and electrical evaluation procedure – applicable for devices with a supply voltage up to 1000 V (d.c./a.c./pulse), – using a wire-wound coil model; this model may be used for wire-wound applications, such as transformers, chokes, ballasts, reactors, ferrite converters, etc., – with minimum test life of 1500 h at the lowest ageing temperature, – for products that are not normally subjected to vibration. The model shall contain all components of the final product in order to determine chemical interaction under thermal ageing conditions. No modifications are allowed because this ageing program is designed to evaluate the entire EIS.

IEC TS 61934:2011

Tue, 05 Nov 2024 20:10:28 +0000

IEC/TS 61934:2011(E) is applicable to the off-line electrical measurement of partial discharges (PD) that occur in electrical insulation systems (EIS) when stressed by repetitive voltage impulses generated from electronic power devices. Typical applications are EIS belonging to apparatus driven by power electronics, such as motors, inductive reactors and windmill generators. Excluded from the scope of this technical specification are:
– methods based on optical or ultrasonic PD detection,
– fields of application for PD measurements when stressed by non-repetitive impulse voltages such as lightning impulse or switching impulses from switchgear.
The principal changes with regard to the previous edition concern the addition of:
– an Introduction that provides some background information on the progress being made in the field of power electronics;

– impulse generators;

– PD detection methods;

– a new informative Annex C covering practical experience obtained from round-robin testing (RRT);
– example of noise levels, as shown in new informative Annex D.

IEC TR 63040:2016

Tue, 05 Nov 2024 20:07:38 +0000

IEC TR 63040:2016(E) describes test results of research on dimensioning of clearances and creepage distances, for spacing equal to or less than 2 mm for printed wiring material and other equivalent arrangements of insulation, where the clearance and the creepage distance follows the same path along the surface of solid insulation. The information contained in this document is the result of research only and cannot be used for dimensioning the clearances and creepage distances for equipment within low-voltage systems, where IEC 60664-1 applies. However distances can be taken into account for functional reasons. This document provides results of research related to the following criteria:
1) clearances independent from the micro-environment;
2) creepage distances for pollution degree 1, 2 and 3 which extends the use of smaller distances to products having design features similar to printed circuit boards;
3) creepage distances to avoid flashover of the insulating surface;
4) information on minimum creepage distances to maintain minimum insulation resistance.
A test method for the evaluation of the relevant water adsorption group for the surface of any insulating material which has not yet been classified is described.
