Radian Research, Inc. www. radianresearch. com an employee owned company Power and Energy Measurement Specialists Welcome & Thank You! • • 3852 Fortune Drive Lafayette, Indiana USA www. radianresearch. com Model 505 – What is it? Testing Capabilities CT/PT – Why Test? Value in Purchase

Radian Research, Inc. www. radianresearch. com an employee owned company Power and Energy Measurement Specialists What is it? • The Model 505 is a Current Transformer and Potential Transformer Analyzer – It’s a small portable tester for testing CT’s and PT’s in- or out of-service – It provides test data to determine if the CT’s or PT’s are bad – It helps diagnose installation issues 3852 Fortune Drive Lafayette, Indiana USA www. radianresearch. com

Radian Research, Inc. www. radianresearch. com an employee owned company Power and Energy Measurement Specialists What is a CT? l A Current Transformer that reduces high primary current to 5 amps for measurement by a revenue meter. l A CT is designed to make this reduction accurately when driving the secondary current into a known burden. l If the secondary burden is exceeded, the CT’s accuracy will be compromised. 3852 Fortune Drive Lafayette, Indiana USA www. radianresearch. com

Radian Research, Inc. www. radianresearch. com an employee owned company Power and Energy Measurement Specialists CT Accuracies What is meant by +/- 0. 3 % Between the Burdens of 0. 1 and 0. 5 ohms? – 2. 0 RF 0. 6% 0. 3% -0. 6% 10% 200% or Rating Factor 100% Current • Below 10% and Above Rating Factor Current – Accuracy is not Guaranteed • Above 0. 5 ohms of Total Circuit Burden – Accuracy is not Guaranteed 3852 Fortune Drive Lafayette, Indiana USA www. radianresearch. com

Radian Research, Inc. www. radianresearch. com an employee owned company Power and Energy Measurement Specialists What is BURDEN? The total amount of resistance in Ohms and inductance in Milli-Henries which may be connected to the secondary without causing a measurable error greater than specified by the CT’s accuracy classification. 3852 Fortune Drive Lafayette, Indiana USA www. radianresearch. com

Radian Research, Inc. www. radianresearch. com an employee owned company Power and Energy Measurement Specialists What Makes Up The Burden? • Electricity Meter Current Coils • Meter Socket • Test Switch Components • Wire Gage • All compression connections 3852 Fortune Drive Lafayette, Indiana USA www. radianresearch. com

Radian Research, Inc. www. radianresearch. com an employee owned company Power and Energy Measurement Specialists Installation Issues? • Mis-Wired Installation • Wrong Nameplate Information • Wrong system Multipliers • Lightning strike causes shorted windings or magnetizes the core. • Open Secondary causes failed insulation in CT windings or magnetizes the core • CT age causes Insulation Failure • Installation age/location causes excessive Circuit Burden 3852 Fortune Drive Lafayette, Indiana USA www. radianresearch. com

Radian Research, Inc. www. radianresearch. com an employee owned company Power and Energy Measurement Specialists Model 505 CT/PT Testing Capabilities 3852 Fortune Drive Lafayette, Indiana USA www. radianresearch. com

Radian Research, Inc. www. radianresearch. com an employee owned company Model 505 Admittance Test Power and Energy Measurement Specialists • Tests CT’s in Circuit or out of Circuit (with & without Load) • Easily checks for Open Circuits, Shorted CT’s, Bad CT Windings – all from the Test Switch – Does not Magnetize the CT –Because of sensitivity of the Admittance Testing, large changes in results will be seen on circuits with minor problems. • Results are very repeatable and independent of load. • Results are evaluated by comparing the results to the other CT readings and also comparing the previous results 3852 Fortune Drive Lafayette, Indiana USA www. radianresearch. com

Radian Research, Inc. www. radianresearch. com an employee owned company Model 505 CT Burden Test Power and Energy Measurement Specialists • A Meter Circuit Burden Test is accomplished by inserting a know load (resistance) and comparing the Before and After secondary current measurement. A burden tests helps determine the capability (VA) of the CT. • Acceptable Burden Tests require a reasonable load to be present (50% of rating). • Burden Test Results significantly vary based on the load and require a knowledgeable person to interpret. 3852 Fortune Drive Lafayette, Indiana USA www. radianresearch. com

Radian Research, Inc. www. radianresearch. com an employee owned company Model 505 Demag Power and Energy Measurement Specialists • Utilizes the Burden Resistance to take the CT into saturation and then bring it out of saturation • To ensure the CT is properly Demagged, the CT should be loaded to 50% or more of rating (typically 2. 5 amps) 3852 Fortune Drive Lafayette, Indiana USA www. radianresearch. com

Radian Research, Inc. www. radianresearch. com an employee owned company Model 505 CT Ratio Test Power and Energy Measurement Specialists • A Ratio Test determines the Current Ratio and Phase Angle between the Primary and Secondary Currents on the CT • A Primary Current Probe is utilized for direct primary current measurement • Accurately Measures Actual Ratio and Phase angle between the Primary / Secondary Service 3852 Fortune Drive Lafayette, Indiana USA www. radianresearch. com

Radian Research, Inc. www. radianresearch. com an employee owned company Model 505 PT Burden Test Power and Energy Measurement Specialists • A PT Burden test is used to determine whether a PT has enough VA capability to drive the attached load and provide an accurate voltage to the measurement circuit • To perform the test, varying Burdens (Resistance) are applied to the PT. The Before and After Burden Application is compared. If a change is realized, either the PT is rated too small, significant Burden is in the measuring circuit or too much load (relays, etc. . ) is ‘hung’ on the PT. 3852 Fortune Drive Lafayette, Indiana USA www. radianresearch. com

Radian Research, Inc. www. radianresearch. com an employee owned company Power and Energy Measurement Specialists Model 505 Service Wiring Test • The 505 includes an Accurate Single Phase Digital Volt / Amp / Phase Angle Meter • By Taking a few Measurements – A Tester can accurately determined if the Service is properly Wired • All measurements taken from test switches 3852 Fortune Drive Lafayette, Indiana USA www. radianresearch. com
