Transformer Testing Standards

This standard provides a basis for electronic reporting of transformer test data on liquid-immersed distribution transformers. This standard defines how to format and report the standard test data when electronic reporting is specified. In addition, it defines an...

To aid in the interpretation and application of the impulse testing requirements of the IEEE Standard Test Codes for Transformers. Purpose This guide is written primarily for power transformers, but it is also generally applicable to distribution and instrument...

This standard provides a basis for electronic reporting of transformer test data on liquid immersed distribution transformers, specifically, those defined in the ANSI C57.12.2X standards series. This standard defines the standard set of test data to be reported and the...

PURPOSE AND SCOPE This document contains the site commissioning tests to be performed on Current Transformers in National Grid (NG) substations.'

This document describes the special test for Medium Power Transformers ≤ 3150kVA compliant with the EN 50708 2 series: - for corrugated tank liquid immersed transformers; - for the method of measurement of losses for one winding in Highest Voltage (HV) and 2 windings in Lowest...

This recommended practice presents a number of tests for use in determining the significant parameters and performance characteristics of electronics transformers and inductors. These tests are designed primarily for transformers and inductors used in all types of...

This standard is intended to encompass the dimensions and functions of meter test switches used with transformer-rated watthour meters in conjunction with instrument transformers and test plugs used in conjunction with the test switch.

This Practice provides requirements for design, manufacturing, and testing of impressed cathodic protection system transformer-rectifiers.

This document describes a special test for hermetically sealed transformers with integral filling equipped with corrugated tank or tank with expandable radiators for Large Power Transformers > 3 150 kVA.

The book presents basic theories of transformer operation, design principles and methods used in power transformer designing work, and includes limitation criteria, effective utilization of material, and calculation examples to enhance readers' techniques of transformer design...

Electric Power Transformer Engineering, Third Edition expounds the latest information and developments to engineers who are familiar with basic principles and applications, perhaps including a hands-on working knowledge of power transformers. Targeting all from the merely curious to...

This Instruction applies to uninhibited insulating oils in transformers, switchgear and similar apparatus where sampling is practicable. Low oil volume equipment which does not contain a reserve of oil for testing purposes, or equipment which is not designed for the process of routine...

This guide provides background information and general recommendations of instrumentation, circuitry, calibration, and measurement techniques of no-load losses (excluding auxiliary losses), excitation current, load losses of power, and distribution transformers. The test codes,...

Defines the labeling of distribution transformers tested to the efficiency levels specified in TP 1. This standard defines the labeling of distribution transformers tested to the efficiency levels specified in TP 1. The label shall be affixed to the transformer in...

This recommended practice covers routine impulse tests performed on distribution transformers, as required in IEEE Std C57.12.00™, and described in 10.4 of IEEE Std C57.12.90™-20151. Distribution transformers covered by this recommended practice are liquid-immersed, single- and...

This part of IEC 60076 gives guidance and explanatory comments on the existing procedures for lightning and switching impulse testing of power transformers to supplement the requirements of IEC 60076-3. It is also generally applicable to the testing of reactors, see IEC 60289;...

Includes: Group 1: Transformers (high priority) e.g. grid transformers, including the selector tanks of on-load tap changers and isolating transformers. Group 2: Transformers (low priority) e.g. booster transformers, regulating transformers, auxiliary...
