Elektrinės bandymų įrangos įrengimas ir naudojimas

1.1 This document is applicable to the installation and operation of fixed and temporary electrical test installations. 1.2 Compliance with this document needs to be applied, if contact with live parts presents dangerous. This is the case when: a) the voltage exceeds 25 V AC (frequencies lower than 500 Hz) or 60 V DC and current exceeds 3 mA for AC or 12 mA for DC, or b) the voltage exceeds 25 V AC (for any frequency) or 60 V DC and the discharge energy of the test station and test object exceeds 350 mJ, or c) at frequencies above 500 Hz the national determined current and voltage values are applied. If there are no national requirements, determined reference values for permissible body currents and contact voltages can be taken from Table A.1; This document is applicable even if conditions a) to c) are fulfilled, due to other possible risks, e.g. risk of fire or explosion. NOTE The values for the resultant current of 3 mA AC or 12 mA DC comply with the information about the effects of current on human beings and livestock in IEC/TS 60479 1. 1.3 Some specifications in this document refer to a voltage value of 1 000 V. This value applies to AC voltages and is equated to a value of 1 500 V DC voltage. 1.4 Where no requirements are given in this document, the documents of the HD 60364 series (for nominal voltages up to 1 000 V) or EN IEC 61936 1 and EN 50522 (for nominal voltages exceeding 1 kV) apply to the installation of electrical test installations and EN 50110 1 applies to the operation of electrical test installations. 1.5 This document does not apply to the power supply to the test installations. In this case, the documents of the HD 60364 series (for nominal voltages up to 1 000 V) or EN IEC 61936 1 (for nominal voltages exceeding 1 kV) apply to their installation and EN 50110 1 applies to their operation.

Informacinės technologijos. Duomenų centro įrenginiai ir infrastruktūros. 1 dalis. Bendrosios sąvokos

This document: a) describes the general principles for data centres upon which the requirements of the EN 50600 series are based; b) defines the common aspects of data centres including terminology, parameters and reference models (functional elements and their accommodation) addressing both the size and complexity of their intended purpose; c) describes general aspects of the facilities and infrastructures required to support data centres; d) specifies a classification system, based upon the key criteria of “availability”, “security” and “resource and energy efficiency enablement” over the planned lifetime of the data centre, for the provision of effective facilities and infrastructure; e) details the issues to be addressed in a business risk and operating cost analysis enabling application of the classification of the data centre; f) provides reference to documentation, operation and management of data centres; g) introduces the concepts of Key Performance Indicators (KPIs) for resource management and resilience of data centre facilities and infrastructures; h) defines the use of an environmental sustainability strategy. The following topics are outside of the scope of this series of documents: 1) the selection of information technology and network telecommunications equipment, software and associated configuration issues are outside the scope of this document; 2) quantitative analysis of overall service availability resulting from multi-site data centres; 3) safety and electromagnetic compatibility (EMC) requirements (covered by other standards and regulations. However, information given in this document can be of assistance in meeting these standards and regulations).

Aukštosios įtampos mašinų šynų ir ričių izoliacijos bandymas

This document applies to rotating electrical machines with rated voltages (UN) from 5 kV to 27 kV inclusive and with rated output from 5 MVA upwards for generators and from 5 MW upwards for motors. This document is also applicable to machines with rated outputs between 1 MVA (1 MW) and 5 MVA (5 MW) and with rated voltages of 5 kV and above, provided its use has been agreed beforehand. Requirements for machines with a rated voltage above 27 kV are the subject of individual agreement. In the case of machines whose windings are cured in the stator, tests on the separate winding elements are not possible; for these machines the requirements in Clause 6 apply. Converter fed machines are excluded from the scope of this standard. The described tests can be used for this type of machines however the criteria are mutually agreed upon between user and manufacturer.
