Notify Megger of any shortage. Telephone (610) 676- 8500 and ask for the Customer Service Department. Examine the instrument for damage received in transit. If damage is discovered, file a claim with the carrier at once and notify Megger, giving a detailed description of the damage. This instrument has been thoroughly tested and inspected to meet rigid specifications before being shipped. It is ready for use when set up as indicated in this manual. General Information The DELTA- 3000 is used for shop and field testing of high- voltage electrical insulating systems at test voltages up to 12 kV. Test results can be used to evaluate the nature and quality of electrical insulating materials and manufacturing processes to reveal contamination, fractures, punctures, and other defects that accompany the aging of insulation. The test set comprises a control unit, a high- voltage unit, cables, and a canvas carrying bag. Refer to the Specifications section for a list of included accessories. Tests are made by measuring the capacitance, power factor (dissipation factor) and dielectric losses of a specimen. The values measured will change when undesirable conditions exist, such as moisture on or in the insulation; shorts or opens in windings or insulation; the presence of conductive contaminants in insulating oil, gas or solids; and the presence of internal partial discharges. The test set measu
