SIRIUS89N 8.8.2. Using the Instrument in a Three Phase System CAUTION The maximum voltage between B1 and B4 inputs is 600 V~ (CATII) / 350V~ phase – earth or 600V~ (CATIII) / 300 V~ phase to earth. Do not measure voltages exceeding the limits prescribed by this manual. Should you exceed the voltage limits you could damage the instrument and/or its components or endanger your safety. The instrument is a single phase system.
SIRIUS89N 9. SAVING RESULTS The SAVE button can be used to store the displayed results related to the rotary switch position: SAFETY TEST and for AUX rotary switch position: pressing this key the instrument will store the displayed result generating a corresponding record in the SAFETY TEST MEMORY (see paragraph 11.1) ANALYZER rotary switch position: pressing this key the instrument will store the displayed result generating a "Smp" record in the ANALYZER MEMORY (see paragraph 11.
SIRIUS89N 10. 10.1. RECORDINGS START A RECORDING The recording function is available for ANALYZER and AUX rotary switch position. As you can read in the paragraphs 7.2.1 and 8.2, a recording can be started manually or automatically. Therefore, after setting all the parameters and leaving the Menu, the instrument will start to record: MANUALLY: the recording will start when Instrument time reach the “00” seconds value after pressing START/STOP.
SIRIUS89N 10.2. SETTING TYPICAL CONFIGURATIONS In order to facilitate this task, the instrument is provided of the following two pre-setting recording modes: 1. Default Configuration: it’s comprehensive which should fit most cases. 2. Typical Configuration: it’s possible to select recording with pre-setting parameters for the following situations: EN50160 SURGES & DIPS HARMONICS START-UP POWER & ENERGY Setting parameters for Networks Quality in compliance with EN 50160 standard (see paragraph 16.11.2).
SIRIUS89N As the default value of the integration periods is set at 15 minutes the instrument will store data in the temporary memory for 15 minutes. Afterwards the instrument will elaborate the results saved in the temporary memory and will save the result of this elaboration (min, avg, and max values) in the definitive memory. Therefore, if an integration period of 15 minutes has been set, the recording will continue for about 15 minutes before producing a series of recorded values.

SIRIUS89N ALLOWABLE VALUES The values of test voltage and minimum insulation resistance following table (CEI64-8/6 Tab. 61A): are reported in the Test voltage (V) Insulation resistance (MΩ) SELV and PELV* 250 ≥0.250 Up to 500 V included, except for the above circuits. 500 ≥0.500 1000 ≥1.000 Rated circuit voltage (V) Over 500 V * In the new standards the terms SELV and PELV replace the old definitions "safety low voltage" or "functional".
SIRIUS89N 16.3. Check of the Circuit Separation PURPOSE OF THE TEST The test, to be effected in case the protection is realised through separation (64-8/6 612.4, SELV or PELV or electrical separation), shall check that the insulation resistance measured according to the indications below (depending on the separation type) complies with the limits reported in the table relative to the insulation measurements.
SIRIUS89N EXAMPLE OF CHECKING THE SEPARATION AMONG ELECTRICAL CIRCUITS Insulation or safety transformer making the separation among the circuits. Between the active parts of the separated circuit... ...And among those other circuits Test among the active parts. Connect a test lead of the instrument to one of the two conductors of the separate circuit and the other to one of the conductors of a no separate circuit. Test between the active parts and the earth.
SIRIUS89N ALLOWABLE VALUES The test result is positive when the insulation resistance indicates values higher or equal to those indicated in the table reported in the section relative to insulation tests. Notes: • SELV system: is a system of category zero or very low safety voltage featured by: Power supply: autonomous source (ex. batteries, small generator) or safety (ex. safety transformer).
SIRIUS89N 16.4. Earth Resistance Measurement in TT Systems PURPOSE OF THE TEST Check that the RCD is co-ordinated with the earth resistance value. It is not possible to assume an earth resistance value as reference limit (for example 20Ω according to the art. 326 of DPR 547/55) when controlling the test result, while it is necessary to check every time that the co-ordination complies with the requirements of the standards. INSTALLATION PARTS TO BE CHECKED The earth installation under working conditions.
SIRIUS89N EXAMPLE FOR EARTH RESISTANCE TEST Let’s assume an installation protected by a 30 mA RCD. Let’s measure the earth resistance using one of the methods quoted above, to evaluate whether the installation resistance is complying with the standards in force and multiply the result by 0.03A (30 mA). If the result is lower than 50V (or 25V for special rooms) the installation can be considered as co-ordinated as it respects the above-said relation.
SIRIUS89N phase with voltage and a leakage current phase shifted by 180° with respect to the voltage. The highest time is to be considered as significant result. The test at ½I∆n SHALL NEVER cause the RCD tripping. NOTE: • Before effecting the test at the RCD rated current the instrument carries out a test at ½I∆n to measure the contact voltage and the overall earth resistance; if during this test the RCD trips the indication l "rcd" is displayed.
SIRIUS89N 16.7. Measurement of Short-Circuit Fault Impedance (Zpn, Zpp) PURPOSE OF THE TEST Check that the tripping power of the RCD is higher than the maximum fault current of the installation. INSTALLATION PARTS TO BE CHECKED The test shall be effected in the point where the short circuit current is the highest possible, usually immediately downstream the RCD to be checked.
SIRIUS89N 16.9. Earth Resistivity Measurement PURPOSE OF THE TEST This test aims at analysing the resistivity value of the ground in order to define the type of rods to be used. EQUIPMENT PARTS TO BE TESTED For the resistivity test admissible values do not exist. The various values measured by positioning the rods at growing distances “a” must be quoted in a graph. According to the resulting curve, suitable rods will be chosen.
SIRIUS89N Curve1: as ρ decreases only in depth, it’s possible to use only a rod in depth. 1 Resistivity (Ωm) The measuring method allows to define the specific resistance up to the depth corresponding approximately to the distance “a” between the rods. If you increase the distance “a” you can reach deeper ground layers and check the ground homogeneity.
SIRIUS89N 16.10. VOLTAGE ANOMALIES (VOLTAGE S AND SURGE) The instrument is able to record as voltage anomalies all those rms values, calculated every 10ms, beyond the percent thresholds of Voltage Reference (Vref) set during the programming from 3% to 30 % (with step of 1%). The Reference must be set to: Nominal Voltage Phase to Neutral: Nominal Voltage Phase to Phase: for Single Phase and 4 wires three phase system for 3 wires three phase system Example1: Three Phase System 3 wires.
SIRIUS89N LEGENDA: 1. Fundamental 2. Third Harmonic 3. Distorted Waveform Effect of the sum of 2 multiple frequencies. In the mains voltage, the fundamental has a frequency of 50 Hz, the second harmonic has a frequency of 100 Hz, the third harmonic has a frequency of 150 Hz and so on. Harmonic distortion is a constant problem and should not be confused with short events such as sags, surges or fluctuations. It can be noted that in (1) the index of the sigma is from 1 to the infinite.
SIRIUS89N 16.11.2. Limit values for harmonics EN-50160 fixes the limits for the harmonic voltages, which can be introduced into the network by the power supplier. In normal conditions, during whatever period of a week, 95% if the RMS value of each harmonic voltage, mediated on 10 minutes, will have to be inferior than or equal to the values stated in the following table.
SIRIUS89N 16.11.4. Presence of harmonics: consequences nd th In general, even harmonics, i.e. the 2 , 4 etc., do not cause problems. Triple harmonics, odd multiples of three, are added on the neutral (instead of cancelling each other) thus creating a condition of overheating of the wire which is extremely dangerous.
SIRIUS89N In presence of distorted voltages and currents the previous relations vary as follows: ∞ Phase Active Power: Pn = ∑ Vk n I k n cos (ϕ k n ) (n=1,2,3) k =0 S n = VnN ⋅ I n Phase Apparent Power: (n=1,2,3) Phase Reactive Power: Qn = S n2 − Pn2 (n=1,2,3) Phase Power Factor: PF n = (n=1,2,3) Distorted Power Factor dPFn=cosf1n= (n=1,2,3) Pn Sn phase displacement between the fundamentals of voltage and current of n phase PTOT = P1 + P2 + P3 Total Active Power: Total Reactive Power: QT
SIRIUS89N 16.12.1. Conventions on powers and power factors As for the recognition of the type of reactive power, of the type of power factor and of the direction of the active power, the below conventions must be applied.
SIRIUS89N 16.12.2. 3 Phase 3 Wire System In the electrical systems distributed without neutral, the phase voltages and the power factors and phase cosϕ lose importance. Only the phase to phase voltages, the phase currents and the total powers remain defined. Phase 1 VAR 1-2 W 1-2 Three-phase Phase 2 equipment Phase 3 VAR 3-2 W 3-2 In this case the potential of one of the three phases (for example, phase 2) is taken on as reference potential.
SIRIUS89N 16.13. MEASURING METHOD: OUTLINES The instrument is able to measure: voltages, currents, active powers, inductive and capacitive reactive powers, apparent powers, inductive and capacitive power factors, analogic or impulse parameters. All these parameters are analyzed in a digital way: for each phase (voltage and current), 6 x 128 samples are acquired on a module of 16 x 20ms, repeated for the three phases. 16.13.1.
