A voltage selector fitted on the mains supply

12、 input panel at the rear permits the test sets to be operated from either 110 V, 120 V, 220 V or 240 V 50 Hz/60 Hz mains power supplies. The casing is made of sheet steel and carrying handles are fitted at each side. The whole construction is very robust. Incorporated within the casing is the test c

13、hamber of moulded plastic construction with a hinged polycarbonate cover. Protruding into the chamber from its floor are two horns; through these pass the high voltage transformer output connections, to cradle terminals one at the top of each horn. The test vessel containing the sample of oil to be

14、tested, is placed on these cradle terminals. Within the test vessel are mounted two electrodes. The shape of the electrodes and the gap set between them is determined by the particular national oil testing specification to be used. The vessel itself is of cast resin construction made in two parts. T

15、he electrodes are automatically connected to the cradle terminals when the vessel is placed on the horns. Inset into the top rear panel of the test chamber is a supply socket. This provides an independent power supply for the optional ASTM D1816 American test vessel which has an impeller type oil st

16、irrer. Oil stirring may also be achieved by a magnetic stirrer bar driven by a rotating magnetic field generated from beneath the test chamber. This magnetic field is only generated when required, under software control. The hinged cover to the test chamber is fastened by a trapped key interlock swi

17、tch. This is a safety feature whereby high voltage cannot be applied to the test chamber unless the interlock is closed. Should the interlock be released during an oil testing sequence, the high voltage will be automatically cut off and the test aborted; the display will indicate that this has occur

18、red. However, the mains supply will still be applied and the On/Off switch will still illuminate. Note:- User settable parameters and test results are stored in non-volatile memory (referred to as NOVRAM) and are unaffected by the operation of the test chamber interlock or by power failures. The con

19、trol panel is to the right of the test chamber. Once the testing specification has been selected and a test initiated (via the control panel) the operator is free to do other work while the test sequence is automatically carried out. Below the control panel an integral printer is fitted so that a pe

20、rmanent record of any test results may be obtained. A 9 Way D type plug is fitted to the test set to enable an external printer to be connected if required. Control Panel Test circuitry is controlled by a microprocessor and all the inherent benefits of pre-programmed tests, menu selection of functio

21、n and memory storage of test results are available. Panel controls are: (i) An On/Off power supply rocker switch which illuminates in the On position. (ii) Three tactile keys for making menu selections and generally controlling the test sequences. (iii) A tactile key for advancing the paper through

22、the internal printer. The display is a liquid crystal dot-matrix type giving full information in alpha-numeric form. The display shows the tests which are available, allocates names to the tactile control keys according to the programme adopted, shows the voltage being applied during a test and revi

23、ews the individual test breakdown voltage results when a test sequence is concluded (plus showing the average breakdown voltage and standard deviation). An L.ED. on the control panel illuminates to indicate that a high voltage is being applied to the test electrodes. The menus, and their information

24、 shown on the display are straightforward and simple to follow. The text of the operating section of this instruction book gives detailed information which, after the set has been used once, will probably only need to be referred to if difficulties arise, but please ensure you read thesection entitl

Oil test set controls etc. Figure 1. OTS100AF/2 oil test set layout (the OTS80AF/2 and OTS60

27、AF/2 are similar). Figure 3. Oil test set rear panel. The OTS60AF/2, OTS80AF/2 and OTS100AF/2 are used for determining the dielectric strength of liquid insulants, such as the insulating oils used in transformers, switchgear and other electrical apparatus. They are transportable and suitable for lab

28、oratory use as well as testing on site. A four wheeled trolley is available to assist with on-site transportation. The test sets are fully automatic. The operator has simply to prepare the test vessel, load it with sample oil, place it in the test chamber, select the appropriate specification for th

29、e tests and then start the test sequence. The test set carries out automatically (and if necessary unattended) the sequence of tests as defined by the pre-selected national specification. Oil testing specifications, for which the sets are pre-programmed, are as follows:- InternationalIEC 156 1995 Br

31、96) For other specifications, five separate, fully programmable, custom test sequences are available which can be stored within the non volatile memory (NOVRAM). A 5 minute test sequence is also provided so that a user may quickly obtain an idea of the state of an oil sample. Three types of withstan

32、d (proof) testing of an oil sample are available. The principle of these tests is to subject the oil sample to a specified voltage for a defined length of time (1 minute) to see if it will withstand that voltage. Withstand test A and Withstand test B incorporate a user definable initial stand time p

33、eriod. Safety features incorporated in the design include the trapped key interlock on the test chamber cover and an easily operated mains supply On/Off switch. These ensure a high level of safety for operators, provided the set is used in a responsible manner. Applications 6 Power cord If the power

The test set MUST be connected to a socket outlet with a protective earth conductor. To ensure effective earthing, it is recommended that the green/yellow terminal on the mains input panel at the rear of the test set be separately connected to a known good earth. 2. Before connecting the mains supply, ensure that the mains supply voltage selector is set to the correct value for the power supp
