BS EN 60044-8-2002儀表變壓器.電流變壓器

This part of IEC 60044 applies to newly manufactured electronic current transformers havingan analogue voltage output or a digital output, for use with electrical measuring instrumentsand electrical protective devices at nominal frequencies from 15 Hz to 100 Hz.NOTE Additional requirements due to the bandwidth are considered. The accuracy requirements on harmonics aregiven in annex D.Clause 12 covers the accuracy requirements that are necessary for electronic currenttransformers for use with electrical measuring instruments.Clause 13 covers the accuracy requirements that are necessary for electronic currenttransformers for use with electrical protective relays, and particularly for forms of protection inwhich the prime requirement is to maintain the accuracy up to several times the rated current.If required, the transient accuracy of an electronic current transformer during fault is also givenin this clause.Electronic current transformers intended for both measurement and protection should complywith all the clauses of this standard and are called multipurpose electronic currenttransformers.The transformer technology can be based on optical arrangements equipped with electricalcomponents, on air-core coils (with or without a built-in integrator), or on iron-core coils withintegrated shunt used as a current-to-voltage converter, alone or equipped with electroniccomponents.For analogue output, the electronic current transformer may include the secondary signalcable. Examples of electronic current transformer technologies using air-core coils and ironcorecoils with integrated shunt are given in annex C.For digital output, this standard takes into account a point-to-point connection from theelectronic transformer to electrical measuring instruments and electrical devices (see annex B).Some information has been added in order to ensure the compatibility of this point-to-point linkwith the overall system of communication in the substation, thus allowing data exchangebetween all kinds of substation devices. This information builds what is called the mapping ofthe link layer of the point-to-point serial link. Processbus communication is underconsideration.This mapping allows interoperability between devices from different manufacturers.This standard does not specify individual implementations or products, nor does it constrain theimplementation of entities and interfaces within a computer system. This standard specifies theexternally visible functionality of implementations together with conformance requirements forsuch functionalities.
