QUESTION 10b: HOW IS THIS TEST DONE AND WHAT VALUE OF MEASUREMENT IS ACCEPTABLE?

ANSWER: a) Thetestneedstobeperformedatthedistributionboard. b) Connect the leadsabove theearth leakage circuitbreaker toavoid it fromtripping (seeFig.E,F,G&H-Pg7&8).FigE,F,G&Hshowstypicalinstallationsthatcanbe encountered. c) Makeuseofthetestleadssuppliedwiththetesteronlyasnonstandardleadsmaylead toerroneousreadings.Noextensionleadsshouldbeused. c) Theearthloopimpedancetestwillbeconductedbetweenthephaseandearthconductors and the prospective short circuit current (PSC) will be between the phase and neutralconductor. e) T1825isautorangingandwillautomaticallyselectthemostsuitablerange. f) Pressingthetestbuttonwillmomentarilyinjecta16A(typicalloadcurrent)testcurrent throughthecircuitandaloopimpedancereadingwillbeindicated.Recordthisreading onthetestcertificate. g) Itisacceptedthatacircuitshouldcarryafaultcurrentoftwicetheratedcircuitcurrent.

Tocalculatetheacceptablevalueofmeasurementproceedasperthefollowingformula:

V Remax=2xI(Amps)rated WhereRemax = Maximumearthloopimpedance V = MeasuredVoltage I = RatedCircuitCurrent

Example:60AmpCircuit(I) 230VACSystem(V) V Remas= 2xI 230 =(2x60) = 1.92Ω

Therefore the loop resistance of the circuit must be below 1.92Ω to allow a fault currentof120ampstoflow.

h) Set the tester on the 2000A range on the PSC scale and measure the prospective shortcircuitcurrent.Theresultwillbeindicatedinamps. i) The result should be entered on the front page of the certificate of compliance / testreport.Anexamplecanbefoundonpage282oftheSANS10142-1:2003. (See addendumB–Pg9). j) Inthecaseofsupplysystemsratedatnotmorethan250Vtoearth,measurethePSCC atthepointofcontrolwithacommerciallyavailableinstrument(faultcurrentmeter). Before any instrument is connected, confirm that the instrument is rated for the applicable current rating, in particularwhere the current rating at themain switch disconnectorexceeds100AorthePSCCisexpectedtoexceed10kA. Note 1: Do not measure three-phase PSCC if the meter is not specifically designed for that purpose or for the capacity of supply (or both). In a balanced three-phase system, the three-phase value can be estimated by multiplying the single-phase value by 1.73. Note 2: Ensure that the instrument connections do not add impedance to the circuit measured. CAUTION: Verify the suitability and accuracy of the PSCC instrument with the manufacturer. k) Tocalculateprospectiveshort-circuitcurrent seepage271of theSANS10142-1:2003 (SeeaddendumC–Pg11). l) Itisimportanttotakeintoaccountthedistancefromthetransformerandsizeofsupply cablewheninspectingandacceptingthekAratingofthecircuitbreakerandinstallation.

Note 1: Do not measure three-phase PSCC if the meter is not specifically designed for that purpose

or for the capacity supply (or both). In a balanced three-phase system, the three-phase value can

be estimated by multiplying the single-phase value by 1.73.

Note 2: Ensure that the instrument connections do not add impedance to the circuit measured.

CAUTION: Verify the suitability and accuracy of the PSCC instrument with the manufacturer.

ANSWER: a) Testthatthepolarityonallswitches,sockets,applianceterminalsandpointsof consumptionarecorrect. b) Insert the TEL1TLB into all sockets, switch on and confirm polarity. Adaptors couldbeusedwhenterminalsareopen. c) Thecorrectwiringwillbeindicatedby3lights.Allmustbeonforcorrectstatus. d) Ifanyofthelightsremainoff,thetableontheinstrumentwillindicatethefault condition. e) To test at a light switch, remove the cover, confirm visually that the phase conductor(Red)hasbeenused.Anon-contactvoltagedetectorcanbeusedto verifypolarityasthiswillonlyfunctionwiththemagneticfieldofalive/phase conductor. f) A phase rotation test must also be carried out if it is a 3 phase installation. This is not applicableon a singlephase. Results should then alsobe recorded on the front of the certificate of compliance / test report (page 282 of SANS10142-1:2003)asillustratedinAddendumB–Pg9. g) The results can only be correct, if a fault is detected it must be rectified immediately.
