Power transformers - Part 19-1: Rules for the determination of uncertainties in the measurement of the losses of power transformers
EN IEC 60076-19-1:2023

IEC 60076-19-1:2023 defines the procedures that are applied to evaluate the uncertainty affecting the measurements of no-load and load losses during the routine tests on power transformers.
This document centres on measuring systems utilizing digital instruments, although the procedures can be adapted to evaluation of systems with analogue instruments where further uncertainty sources have to be taken into account.
This document specifies how to determine measurement uncertainty and how to apply corrections for known errors in the measurement chain. Information vis-à-vis judgement and traceability are given in IEC 60076-8:1997, 10.1 and 10.2.

Power transformers - Part 25: Neutral grounding resistors (IEC 60076-25:2023)
EN IEC 60076-25:2023

This part of IEC 60076 applies to dry type natural air-cooled resistors, for neutral grounding of
transformers and generators, in order to limit the earth fault current in power systems by means
of metallic resistive elements.
For the purposes of this document, the resistor can be:
• used alone or in combination with other electrotechnical products not covered by this
document, such as (but not limited to): a step-down single-phase transformer, an open
triangle or zig-zag transformer (where the neutral point is not available) and a Petersen coil
reactor (in order to increase active power contribution to the fault or reduce time constant
for proper protection operation or both);
• designed, manufactured and verified on a one-off basis or fully standardized and
manufactured in quantity.
Both terms "neutral grounding resistor" (NGR) and "neutral earthing resistor" (NER) can be
used. However, for the purposes of this document and in order to avoid any confusion with
"neutral earthing reactor" (NER), the term "neutral grounding resistor" (NGR) is used.
This document specifies:
• the characteristics of the NGR;
• the service conditions requirements for NGRs;
• the tests and test methods for confirming that these conditions have been met;
• the requirements relating to marking for NGRs.
Annex A provides guidance on how to consider the effect of resistance variation with
temperature.
