14、ral Description 4 The S1-5005 is a compact, automated high voltage, battery powered instrument used to carry out Polarization Index, Step Voltage, and Dielectric Discharge tests as well as spot Insulation tests. The S 1 - 5 0 0 5 has a resistance measurement capability up to 5 T and leakage current

15、measurement enables resistances up to 500 T to be measured. The design of the instrument takes full advantage of microprocessor technology and features a large, clear liquid crystal d i s p l a y, combining digital and analogue readings of insulation r e s i s t a n c e . Set nominal voltage options

16、 of 500 V, 1000 V, 2500 V and 5000 V are selectable. A variable output voltage setting provides a range of 25 V to 5000 V incremental in 25 V steps. At switch on, the instrument carries out a calibration self check which automatically adjusts the measurement system. T h e calibration sequence inhibi

During a test, measurements are automatically sent every 5 seconds via an isolated optical link to the RS 232 connector to enable downloading of the results to a co

19、mputer. final resistance value, and capacitance value. Custom timed DD values can be set if required (see Custom timed DD test). Step Voltage Testing (SV) This 5 minute test depends on the principle that an ideal insulator will produce identical resistance readings at all voltages. Conversely, an in

20、sulator which is being over stressed will show lower values at higher voltages. Operating at either 2,5 kV or 5 kV, the voltage steps up one fifth every minute, and successive measurements are taken. On completion, each of the 5 separate results are sequentially displayed followed by the capacitance

21、 value. Fault Conditioning (Burn) This low current feature is used to carry out continuous testing under breakdown conditions. General Notes: 1) Acapacitance value reading is only available if the test has run for more than one minute, and the reading was not over-range. 2) Internal discharge resist

22、ors are automatically selected :- -At the end of a test. -If the instrument is switched off. -If an internal error is detected. Any voltage remaining on the terminals at the end of a test,will be displayed until it has decayed to less than 50 V. During a test output terminal voltage is displayed, to

Test Mode Summary 5 Insulation Resistance Testing (R) This mode measures insulation resistance at the selected voltage to provide an instantaneous spot reading. Final test result is given sequentially with the corresponding leakage

24、 current and capacitance v a l u e . Test Current measurement (I) This mode measures insulation at the selected voltage to provide an instantaneous spot reading, but displays leakage current value on the digital display. (N.B. The analogue scale always displays resistance). Final test result is give

25、n sequentially with the corresponding resistance and capacitance value. Polarization Index Testing (PI) Polarization Index is the term applied to the Dielectric Absorption ratio, when the insulator is subjected to an insulation resistance test, and the resistance values are measured after time T1 (D

26、efault 1 minute) and again after time T2 (Default 10 minutes). Polarization Index is calculated automatically from the resistance value after time T2, divided by the resistance value after time T1. High dielectric absorption is indicated by high PI ratio (see Application of test Techniques). Final t

27、est results are given sequentially with the corresponding leakage current and capacitance value. The test will run at any voltage. Custom timed PI values can be set if required (see Custom timed PI test). Dielectric Discharge Testing (DD) This mode measures the dielectric absorption of an item under

28、 test while ignoring the effects of parallel surface leakage paths. Default test time is 30 minutes followed by 1 minute discharge.

33、in progress, or a hazardous voltage is present. General It is advisable to fully charge the battery before the instrument is put into service for the first time. Charging is carried out by external a.c. mains supply, or by 12 V d.c. supply. A 12 V charging lead fitted with an automotive cigar lighte

34、r plug is available for charging the battery from a vehicle.Testing is inhibited during charging. Mains supply re-charging Mains input recharging requires a voltage within the range 95 - 265 V a.c., 50 - 60 Hz. Disconnect the test leads and connect the mains supply to the IEC 320 connector in the ch

35、arging recess. Confirm that the red indicator lamp is illuminated. Charging is automatic as soon as the mains supply is connected. To fully recharge the battery takes about 16 hours. Eight hours charging (from a fully discharged state) will achieve at least 90% of full charge. Turn the instrument on

36、 and check the battery capacity indicator to show the state of charge. 12 V d.c. supply re-charging This method of re-charging should only be carried out if a mains supply is unavailable as it is slower and less efficient. If using a vehicle as the charging source, the engine should be running. Obse

37、rving correct polarities shown, connect the 12 V DIN socket to the external 12 V d.c. supply and switch on. Caution: Applying more than 15 V to this socket will overcharge the battery. 12 V DIN socket (Viewed from front of panel). Battery Charging Notes 1)Do not leave battery in a totally discharged

38、 state. Frequent charging to keep the battery topped up will maximise battery life. 2)Battery charging should be carried out in a dry environment (the IP54 environmental protection applies with the charging cover securely closed). 3)When charging the battery indoors, the area should be well ventilat

39、ed. 4)The battery should only be charged at temperatures in the range 0 C to 40 C. 5)It is beneficial to continue charging and no harm will occur to the battery if the charger is left on indefinitely. 6)If the instrument is idle for long periods, recharge the battery for at least 24 hours every 6 mo

41、 and the instrument turned off before touching any connections. 9.The S 1 - 5 0 0 5 has an environmental protection classification of IP54 with the charging recess cover securely closed. It is important from a safety point of view (and to avoid unwanted leakage currents) to ensure that the testing t

42、erminal area and the charging recess are kept free from dirt and moisture. 10. Before use, any surface water on the instrument must be removed, especially from the test lead sockets 11. Fuse replacements must be of the correct type and rating. Refer to the Specification section for correct replaceme

Earth (Ground)Yellow/GreenGreen Neutral BlueWhite Phase (Line)Brown Black Operation 8 Testing Precautions 1.The instrument must only be used by suitably trained and competent persons. 2.Circuit connections must not be touched

45、 during a test. 3. The S 1 - 5 0 0 5can give an electric shock. Highly capacitive circuits (e.g. long lengths of cable) charged to several kV can create a potentially lethal charge. 4.Care must be taken to prevent capacitive circuits becoming disconnected during a test, leaving the circuit in a char

46、ged state. 5.The voltmeter and automatic discharge feature of the S1-5005 should be regarded as additional safety features and not a substitute for normal safe working practice. 6. When carrying out prolonged tests unattended, care should be taken that no harm or damage can be caused. 7.When using t

47、he BURN feature, care should be taken that no harm or significant damage can be caused. 8.In certain circumstances, break-down of the circuit under test may conceivably cause the instrument to terminate the test, possibly causing a loss of display while the circuit remains energised. In this event,

48、the circuit must be The circuit under test must be completely de-energized and isolated before test connections are made. 6.Start a test by pressing the red test button for at least 1 second. The flashing red LED and the flashing H.V. symbols warn that a test is in progress. 7.When testing resistive

49、 or moderately capacitive loads (up to about 1F) the test voltage will appear within a few seconds. The test voltage is controlled to within 5% of nominal, adjusting itself for changes in resistance. The actual output voltage is displayed during tests. On large capacitive items the voltage rise will be noticeably slower and on low resistances (less than 10 M) the voltage may never rise to its nominal value. 8.Insulation resistance readings are updated once every second for measurements up to about 100 M. For measurements between 1 G and infinity the sample f
