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: short-time...
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 design...
PURPOSE AND SCOPE This document contains the site commissioning tests to be performed on Current Transformers in National Grid (NG) substations.'
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 Requirements for...
This part of IEC 61869 provides all requirements specific to current transformers to be used in DC applications (DCCTs), whatever the technology used. The output signal can be analogue or digital. It is applicable to newly manufactured current transformers used for...
This part of IEC 61869 is a product standard and covers only additional requirements for lowpower passive current transformers. The product standard for low-power passive current transformers comprises IEC 61869-1, together with IEC 61869-6 and this document with...
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 describes...
