PURPOSE AND SCOPE This document contains the site commissioning tests to be performed on Current Transformers in National Grid (NG) substations.'
Current transformers for frequencies 14 Hz to 100 Hz for use with electrical measuring instruments and electrical protective devices. Ratings; accuracy; tests; rating-plate and terminal markings. Appendices on guidance in application of current transformers:...
Purpose This Handbook describes the tests to be carried out on current transformers during both stage 1 and stage 2 commissioning (TP106). The purpose of the CT commissioning tests is to prove that the equipment supplied is in accordance with requirements detailed in the...
This part of IEC 60044 applies to newly manufactured current transformers for use with electrical measuring instruments and electrical protective devices at frequencies from 15 Hz to 100 Hz. Although the requirements relate basically to transformers with separate windings, they...
This part of IEC 60044 applies to newly manufactured current transformers for use with electrical measuring instruments and electrical protective devices at frequencies from 15 Hz to 100 Hz. Although the requirements relate basically to transformers with separate windings, they...
The scope of this guide is to describe field test methods that assure current transformers (CTs) are connected properly, are of marked ratio and polarity, and are in a condition to perform as designed both initially and after being in service for a period of time. Annex A...
This part of IEC 60044 applies to newly manufactured electrical current transducers having an analogue voltage output or a digital output, for use with electrical measuring instruments and electrical protective devices at nominal frequencies from 15 Hz to 100 Hz. Clause 12 covers the...
General This part of IEC 60044 applies to newly manufactured electronic current transformers having an analogue voltage output or a digital output, for use with electrical measuring instruments and electrical protective devices at nominal frequencies from 15 Hz to 100 Hz. NOTE...
General This part of IEC 60044 applies to newly manufactured electronic current transformers having an analogue voltage output or a digital output, for use with electrical measuring instruments and electrical protective devices at nominal frequencies from 15 Hz to 100 Hz. NOTE...
This standard is intended to define the requirements for current transformers with a maximum of secondary output of 250 milliamperes. These requirements of ratios, Accuracy classes, burdens and test methods supplement but are not subordinate to IEEE C57.13™ Standard...
The standards of this section apply to constant current transformers of the moving coil type. Standards for other types of transformers are the subjects of separate sections.
IEC 61869-2:2012 is applicable to newly manufactured inductive current transformers for use with electrical measuring instruments and/or electrical protective devices having rated frequencies from 15 Hz to 100 Hz. This International Standard is to be used in conjunction with, and is...
This part of IEC 61869 is applicable to newly manufactured inductive current transformers for use with electrical measuring instruments and/or electrical protective devices having rated frequencies from 15 Hz to 100 Hz.
This part of IEC 61869 is applicable to newly manufactured inductive current transformers for use with electrical measuring instruments and/or electrical protective devices having rated frequencies from 15 Hz to 100 Hz.
PURPOSE The purpose of this procedure is to provide a model process for primary injection testing of feeder protection. The tests are intended to establish the integrity of the associated current transformers and their secondary connections. These tests are...
This International Standard is applicable to newly manufactured current transformers used for measuring, protection and/or control applications in DC Power systems with a voltage above 1 kV. The general configuration of a low power instrument transformer is described in the...
