MLGW began to test each of its transformers for furans in 2009. The results produced a good baseline. A 40-year-old transformer showed a degree of polymerization of 260 in early 2010 during testing, with estimated remaining life at 19 percent. The transformer was immediately taken offline and internally inspected to identify any problems.

Apr 26, 2019 · Insulation Resistance Test: The insulation resistance test determines whether the resistance readings remain constant. If there is a significant drop, there is a problem. Winding Resistance Test: In this test, you divide the voltage drop across the winding by the DC current readings through the windings. A consistent figure indicates no issues.
Time Resistance Test. This test applies a selected voltage over two periods of time. The first period is usually at 10 minutes and the second period is at 1 minute. If the equipment insulation is good, the insulation resistance increases over time.

Dec 28, 2008 · INSULATION RESISTANCE . R = Insulation Resistance of Winding to Ground at 20 o C. C = 0.8 for oil filled transformer at 20 o C. C = 16 for dry compound filled or un tanked oil filled transformer. E = Voltage rating of winding under test. KVA = Rated Capacity of winding under test
Portable insulation resistance testers and megohmmeters are designed to help prevent hazards such as electric shock and short-circuits caused when the insulation in electrical devices, parts, and equipment used in industrial plants, buildings, and other settings degrades over long periods of use. Insulation resistance testers apply high DC voltage which causes a small current through the insulation being tested. The tester then provides a resistance reading. Good insulation should have high resistance and typical values are in the MΩ or GΩ range. This transformer as a low leakage reactance for which the knowledge of the transformer’s secondary excitation characteristics, secondary winding resistance, secondary burden resistance and turns ratio is sufficient to assess its performance in relation to the protective relay system with which it is to be used.
