This document discusses current transformer (CT) testing theory and practice. It covers the differences between self-contained and transformer-rated meters, and describes the functions and terminology used for CTs, including ratio, thermal rating factor, accuracy classifications, and burden. It explains how to test CTs for correct ratio and functionality at rated burdens through both analog and digital methods. Testing involves measuring the secondary current with no burden applied and comparing it to the current reading when various burden levels are applied to ensure accurate performance within specifications.

Current transformers (CTs) are tested for correct ratio and functionality at rated burdens. Ratio testing involves measuring the primary and secondary currents to calculate the ratio. Burden testing applies varying levels of burden to the secondary loop to ensure the CT maintains accuracy within 0.3% up to 0.5 ohms of burden, as specified by ANSI standards. Admittance testing uses an audio frequency signal to measure the "health" of the secondary loop. CTs can become magnetized over time and may need to be demagnetized by slowly increasing and decreasing the secondary resistance to saturate and remove residual magnetism.
This presentation was for an Advanced Session at North Carolina Meter School and discussed CT functionality Basics, Terminology and Specifications, Ratio Testing, Burden Testing, Admittance Testing, and Demag Functions.

Experimental simulation analysis for single phase transformer testsjournalBEEI
Â
Transformer is one of main components in electrical power system which role to increase or reduce voltage. Characteristics of transformer would be vital to ensure the voltage is fully transferred. A single-phase transformer is a type of power transformer that utilizes single-phase alternating current, meaning the transformer relies on a voltage cycle that operates in a unified time phase. This article describes a workflow executed with Mat lab simulation and practical measurements for single-phase power transformer, no-load, short-circuit test and load test are achieved in this work. The test procedures are implemented on areal transformer (terco-type) which has a specification (1 KVA, 220/110 V, 50 Hz). Finally, the simulation results are appeared a proximately seminar from the practical results. The results indicated that the the technique and manner which presented in the current study can be depended as a miniproject in electrical technology mater for undergraduate studies.
This presentation will cover the basics and differences between self-contained and transformer or instrument rated meter sites. Also discussed are transformer rated meter forms, test switches and CT's, Blondel's Theorem and why this matters to metering, meter accuracy testing in the field, checking the health of your CT's and PT's, and Site Verification (and not just meter testing).
This document describes laboratory experiments performed on a single-phase transformer to analyze its performance under open circuit, short circuit, and loaded conditions. In the open circuit test, no load current and iron losses were measured at various supply voltages. The short circuit test involved measuring current and power when the secondary was shorted with a low voltage supply. Finally, the load test analyzed voltage regulation for resistive and capacitive loads by measuring supply voltage, current, and power output. Graphs of the results were plotted to characterize the transformer's performance under different conditions.
Substations are facilities that receive power from generating stations and transmit it to consumers at varying voltage levels using transformers and other equipment. They allow for control of voltage, frequency, and power flow. Major substation equipment includes transformers, current and potential transformers, isolators, bus bars, circuit breakers, relays, and capacitor banks. Substations are classified by their application as generation, transmission, distribution, etc. Maintaining a high power factor is important for efficient power transmission, and capacitor banks can be used in substations for power factor correction.
Instrument transformers, including current and voltage transformers, produce a scaled down replica of primary system quantities (current or voltage) for measurement and protection applications. Current transformers are specified based on their accuracy class, VA burden, and limit or accuracy factor, while voltage transformers are specified based on their voltage and phase angle errors. Both current and voltage transformers undergo various tests to evaluate their performance and ensure proper operation, such as ratio, polarity, excitation, insulation resistance, and winding resistance tests.
This document summarizes a paper presented at the 23rd International Conference on Electricity Distribution in Lyon, France in 2015. The paper proposes a new algorithm for determining the position of an On-Load Tap Changer (OLTC) using primary and secondary currents and voltages measured by Intelligent Electronic Devices (IEDs). The algorithm accounts for various sources of error. Practical testing on multiple transformers showed the algorithm can accurately determine OLTC position within 0.5 steps at loads between 20-90% using currents, and up to 30% using voltages. The algorithm could improve reliability for OLTC position monitoring, transformer automation and more sensitive differential protection settings.
This document discusses output capacitor selection for low voltage, high current power supplies used in applications like microprocessors. It derives an equation to calculate the minimum number of capacitors needed to meet transient voltage regulation requirements during load current steps. Different capacitor types are compared based on this calculation, including electrolytic, tantalum, ceramic, and polymer capacitors. Simulation and experimental results are presented to verify the theoretical analysis. The analysis shows that the minimum capacitors required depends on factors like equivalent series resistance, capacitance, current step size, and whether the system frequency is higher or lower than the capacitor's zero frequency. This methodology allows engineers to optimize capacitor selection for cost and performance.
Current transformers are used to measure high alternating currents and provide safety isolation. They work by inducing a current in the secondary winding that is proportional to the primary current passing through the transformer core. Current transformers scale down large primary currents to safer secondary currents used for instrumentation and protection devices. They are used extensively in power generation, transmission and distribution systems to monitor operations and protect equipment.
This presentation, given by Georgia Power for the Caribbean Meter School, covers transformer rated service installations including field meter testing, instrument transformers, system analyzers, and safety protocols. Several grids are included showing single phase service, three phase services, power factor, harmonics, and more.
This document provides an introduction and overview of current transformer performance analysis. It defines key terms related to current transformers like excitation curve, knee point, and accuracy class. It also outlines the steps to evaluate current transformer performance for phase faults, including selecting a CT ratio, relay tap, determining total burden, and analyzing performance using ANSI/IEEE standards and the excitation curve method. An example is provided to demonstrate calculating CT performance using the excitation curve for a fault current of 12500 amps.

Whatâs the Difference?
Different Forms for Different Services and
Applications
7. 7
CTâs â Functions and Terminology
Ratio
Equivalent Circuit w/ losses
Conceptual Picture of a CT
As current is applied in the primary, it produces a
magnetic flux in the core. This flux flows through the
core and induces a current in the secondary
windings and circuit that is proportional to the
number of turns.
8. 8
CTâs â Functions and Terminology
Ratio
For instance, a CT with a 400:5 ratio will produce
5A on the secondary, when 400A are applied
to the primary.
9. 9
CTâs â Functions and Terminology
Thermal Rating Factor
A value representing the amount by which the
primary current can be increased without
exceeding the allowable temperature rise.
For instance, a RF of 4.0 at 30° ambient on a
400:5 ratio CT would allow for a primary current
up to 1600A.
10. 10
CTâs â Functions and Terminology
Accuracy Classifications and Burden
All CTâs fall within an accuracy class.
IEEE Standards have defined accuracy classes.
