CHAPTER 2

PRODUCT FEATURES

2.1 DescriptionTheDigital TransformerRatiometerDTR®Model 8510 is a lightweight,rugged,portableinstrumentdesignedforonsitetestingofpower,potentialandcurrenttransformers.

OperationoftheDTR®8510isfullyautomatic.Nousercalibration,rangeselection,handcrankingortediousbalancingisrequired.

During each test cycle, the DTR® 8510 automatically checks for:

H/Xleadreversal•

Continuityoftestedcircuits/windings(ifconfigured)•

Shortcircuitconditions(highcurrent)•

Upon completion of a test cycle, the DTR® 8510 displays:Turns Ratio:• Theratiooftheprimarytosecondaryvoltageatthetransformerterminalsduetotestexcitation.

Excitation Current: • TheRMSexcitationcurrentintheHwindingduetotestexcitationduringnegligibleloadingoftheassociatedXwinding.

Polarity:• Indicatesthepolarity(phase)ofXrelativetoH.

Deviation: • Indicatesthedeviationfromnameplateratioin%.

TurnsRatio,ExcitationCurrent,PolarityandDeviationareusefulparam-etersindiagnosingandpredictingavarietyoffaultsthatoccurinpower,potentialandcurrenttransformers.


The DTR® 8510 will display the following messages:IncorrectLeadConnections•H/XReversal(accidentalstep-upmisconnection)•Short(excessexcitationcurrent)•OpenCircuits•CircuitContinuity•LowBattery•

DataView®allowsfullcontroloftheinstrument.

The DTR® 8510 utilizes an advanced, low-voltage, step-down measure-ment technique in which the high voltage “H” windings are subjected to test excitation. This results in greater operator safety and the ability to test a much wider array of transformer types and sizes.

5.3 Tips for Making Precise Ratio Measurements

TheDTR®Model8510isdesignedforstep-downtransformers.Itsourceslow voltage on the primary. It starts with a fraction of the final sourcevoltageandchecksthesecondaryvoltage.Ifitexceedstheprimarybyapre-determinedvalue,thesafetyfeaturestopsthemeasurement.TherecommendedprocedureistoreversetheleadsinthesecircumstancessothattheprimaryofthetransformerisconnectedtotheHcablesandthesecondaryofthetransformerisconnectedtotheXcables.

CAUTION: It is important to check that the H cables are connected to the primary side and the X cables are connected to the secondary side of the transformer before the test begins.

Alwaysverifytheintegrityofthecableconnectionsandreposition•theclipsasnecessaryforrobustandlow-resistanceconnections.Inspectthetransformerterminalsfordielectriccoatings,fungus,dirtor corrosion.

Runningacontinuitytestbeforetheratiotestwillprovideauseful•waytocheckwindingsandconnections.

Whentestingpolyphasetransformers,keepinmindthatinsome•cases,themeasuredratiosmustbemultipliedordividedby√3.Referto§6forpolyphaseconnectiondiagramsandassociatedratioequations.
