The aim of using SLF test is to reduce the volume and weight of test equipment as much as possible on condition that the test meets the requirement. Compared with power frequency test, the SLF test has many advantages on condition that test voltage is the same. The capacity of SLF test equipment can be reduced by 50/(0.01-0.1) = 500-5000 times.

The induced voltage acceptance test with PD measurement (AC-IVPD test, see Sect. 3.2.5, Table 3.6 and Fig. 3.51) shall be performed on the same voltage level as required for the routine test. As a consequence of these requirements of IEC 60076-3, HV on-site test systems have to generate test voltages with parameters as for routine tests in factory.

capacitor is fully discharged. A conventional A.C. line of relatively low power can be utilized to charge a capacitor to rather high potential (e.g., 100 kV).The voltage on the capacitor can then be applied to an x-ray tube to produce x-radiation. For a very short exposure of relatively low mAs, this method produces excellent results.However,
1kV Megohmmeter commonly used in the field to test electrical insulation. Photo: Megger There are three different tests that can be performed with the Megohmmeter. A strong understanding of these common test methods is an important tool in gaining the ability to determine the condition and quality of electrical insulation. Tests are typically conducted by …
A sensitive capacitance meter is used to measure the capacitance of the bank as whole to ensure the connection of the bank is as per specification. If the measured value is not as calculated, there must be some wrong connection in the bank which to be rectified. For measuring capacitance of a bank, we need not to apply full rated voltage, instead only 10 % of …
A minor disadvantage of the ac hipot tester is that if the circuit under test has large values of Y capacitors, then, depending on the current trip setting of the hipot tester, the ac tester could indicate a failure. Most safety standards allow the user to disconnect the Y capacitors prior to testing or, alternatively, to use a dc hipot tester.
