Types of Electrical Transformer Tests· Power Factor Testing . The power factor test determines the power loss of the transformer's insulation system by measuring the power angle between an applied AC voltage and the resultant current.Power factor is defined as the cosine of the phase angle between voltage and current. For ideal insulation, the phase angle is 90 degrees, but in practice, no insulation is ideal.
End-of-life factors in high voltage gas insulated ...· For GIS with SF6 gas : Where a loss of gas from a compartment is identified, external checks with leak detection methods may allow the source of the leak to be determined. by the methods applicable to locating leaks in service, negative ion capture detectors and electron capture detectors are stated to have sensitivities of 20 mg/a SF6 or 1 ...

Jual WIKA SF6 Gas Density Monitor - INSTRUMENT density is a crucial operating parameter for high-voltage switchgear. If the required gas density is not present, safe operation of the plant cannot be guaranteed. The gas density measuring instruments from WIKA warn reliably against dangerously low gas quantities, even under extreme environmental conditions. If the gas density drops
Transformer temperature, oil level and pressure gauges· Transformer pressure gauge. If the transformer is equipped with a constant-pressure nitrogen oil preservation system, then pressure gauges are included to measure the pressure of the gas blanket and the nitrogen in the make-up bottle.. Transformers that have a gas blanket over the oil in the main tank usually come equipped with pressure gauges.
