This International Standard is applicable to string insulator units of the long rod type with
insulating parts of ceramic material intended for use in AC overhead power lines with a
nominal voltage greater than 1 000 V and a frequency not greater than 100 Hz. It is also
applicable to insulators of similar design, used in substations.
This document is applicable to ceramic string insulator units of the long rod type, either with a
clevis end fitting at both ends for coupling with a tongue, or with a socket end fitting at both
ends for coupling with a pin ball.
The object of this document is to prescribe specified values for electrical and mechanical
characteristics, and for the principal dimensions of ceramic string insulator units of the long
rod type.
This document is applicable to string insulator units for use on overhead lines situated in
lightly polluted areas, and the creepage distances given in Table 1 have been established
accordingly, using the IEC TS 60815-2 recommendation of 27,8 mm/kV for SPS class.
However, shorter creepage distances are applicable for use in some non-polluted areas. If
specific operating conditions require or allow non-standard (longer or shorter) creepage
distances, the mechanical characteristics as well as the lengths L (see Clause 4) of this
document are intended to be used unless the need for exceptionally long creepage distances
requires values of L greater than those given in Table 1. In the case of special requirements,
e.g. very heavy polluted areas and for other particular or extreme environmental conditions, it
may be necessary for certain dimensions to be changed.
As far as reasonably applicable, this document is also applicable to be applied to similar
insulator units outside the scope of this standard, such as insulators for electric traction lines.
This document does not include tests on insulators and dimensions of end fittings.
Ball and socket couplings are covered by IEC 60120, clevis and tongue couplings by
IEC 60471.
NOTE 1 For the definition of site pollution severity, see applicable part of IEC TS 60815.
NOTE 2 The term "ceramic" is used in this document to refer to porcelain materials and, contrary to North
American practice, does not include glass.

IEC 61243-1:2021 is applicable to portable voltage detectors, with or without built-in power sources, to be used on electrical systems for voltages of 1 kV to 800 kV AC, and frequencies of 50 Hz and/or 60 Hz.
This document applies only to voltage detectors of capacitive type used in contact with the bare part to be tested, as a complete device including its insulating element or as a separate device, adaptable to an insulating stick which, as a separate tool, is not covered by this document (see 4.4.2.1 for general design).
Other types of voltage detectors are not covered by this document.
Self ranging voltage detectors (formally "multi range voltage detectors") are not covered by this document.
Some restrictions or formal interdictions on their use are applicable in case of switchgear of IEC 62271 series design, due to insulation coordination, on overhead line systems of electrified railways (see Annex B) and systems without neutral reference. For systems without neutral reference, the insulating level is adapted to the maximum possible voltage to the earth (ground).
Products designed and manufactured according to this document contribute to the safety of users provided they are used by persons trained for the work, in accordance with the hot stick working method and the instructions for use.
Except where otherwise specified, all the voltages defined in this document refer to values of phase-to-phase voltages of three-phase systems. In other systems, the applicable phase-to-phase or phase-to-earth (ground) voltages are used to determine the operating voltage.
This third edition cancels and replaces the second edition published in 2003 and Amend-ment 1:2009. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) The scope is more precise, stating that only bare contact to the part to be tested is reliable for these contact voltage detectors. The rationale is that tests on painted or coated conductors have led to wrong indications, as this non-conductive paint or coat acts as a capacitor with different capacity according to the thickness. This capacity has an effect on the threshold voltage.
b) A contact probe is introduced as a new type of non-conductive contact electrode.
c) A new type "exclusively outdoor type" has been defined and implemented into the requirements and test procedure.
d) A selector for voltage and frequency is allowed if foreseeable misuse is excluded.
e) The marking for voltage detectors with low interference voltage has been made more precise.
f) The indication groups have been made more precise and requirements and tests for the "ready to operate state" and "stand-by state" added.
g) Requirements and tests for electromagnetic compatability have been implemented.
h) An example for good electrical connection for the tests is introduced.
