Doble M4000 User Guide
A new file structure has been implemented, allowing user-specified file names for easier data manipulation. While making the various types of connections involved in the different tests, it may be necessary for personnel to climb up on the apparatus, but no one should remain on the apparatus during the test itself.
You may need to install this software if you are loading it onto an office computer or laptop, upgrading from a previous version, or reinstalling it. Isolate the cause by restarting a test after alternately: Do not press the safety switches until the final pre-test warning screen is displayed.
All tests should be performed with the apparatus under test completely de-energized and isolated from its power systems. This should be the first step in setting up the M The front panel-mounted HV Pothead is a connector providing a high-voltage connection to the specimen under test. The rates at which the voltages are raised and lowered manually are selected separately in the Clipboard configuration and the DTA Configuration.
F 1 July 22, 1. Front Panel Figure 1. The features under what used to be the Edit menu are now found under Test by selecting the Clear menu item. Menu Bar The Menu Bar functions are described as follows: Connect the Safety Ground cable to the M Instrument, and to the ground of the specimen to be tested.
Use, duplication, or disclosure by the U. Buckle and tighten the strap snugly around both the M Instrument and the Mc Controller. Capacitors intended use usage may not contain internal resistors. Clicking on the will display the pop-up list of choices. Test personnel need to remain aware of the work activity taking place around them and alert to the possibility that non-test personnel may hser the test area.
Doble Engineering Company 85 Walnut Street Watertown, MA USA Doble pays to ship replacement components to customers under warranty, and customers are responsible for payment of shipping costs for returns. The test connections and procedure are the same as for testing a liquid-insulation sample, except that the test is conducted in both the UST and GST modes.
The following screen will appear: Three Phase Equivalent, Per Phase, and tests on different taps. Unscrew four captive screws Figure 4. This can also be chosen by selecting About M For Windows from the pull manula menu item. Double-check the cable connections and test parameters.
Replace the Field Calibration Reference. Take the following steps to remove and replace the Front Panel Assembly: The M then calculates and reports test results by converting the sampled data into vector magnitude and phase quantities and applying conventional ac circuit theory.
Both safety switches should be used at all times. You may now store reversal readings on the same line and automatically average the results. F Avoiding Problems Troubleshooting from Symptoms This section provides M troubleshooting guidance based upon observed malfunction symptoms. The unit serial number, which provides warranty information.
Communications error message If any of a variety of communications-related error messages see Appendix C is displayed, take the following steps in sequence until the cause of the problem is identified: The default is Auto, and should not be changed without consulting Doble.
High voltage will not be supplied by the instrument if either of the following circuits and conditions are not satisfied: Subsystem Diagnostics The summary table can be printed or saved as a text file.

Press F2 to start the process, which takes several minutes. July 22, If abnormally low insulation resistance is observed, the condition of the insulation between the center conductor and shield at the clip end of the lead should be checked.
When this is done, the following screen appears: Disconnect it from the M and the specimen. The External Source voltage is not controlled by the M An example of such a file is shown in Figure 4. The Temperature and Relative Humidity Sensor will process temperature and humidity readings at the time of test.
EHV circuit breakers with grading capacitors across the interrupter contacts are especially prone to build up a high voltage charge. F July 22, Measurement Principles M Instrument Both an operator and safety supervisor must be maunal when specimens are tested.
The Testing Mode Figure 1.
