FAQ
Q1: What is the difference between IEC 60156 and ASTM D1816, and which method should we follow?
Answer:
The two standards differ in electrode geometry, gap, stirring and voltage application, and therefore produce different numbers from the same oil. IEC 60156 uses spherical electrodes with a 2.5 mm gap, a motor-driven voltage rise and no forced stirring between breakdowns, which suits mineral insulating oils in European and most Asian specifications. ASTM D1816 uses VDE electrodes with a 1 mm or 2 mm gap, gentle stirring and a specified rest period, and is the usual reference in North American practice.
Follow the method named in the purchase specification, the asset owner's maintenance procedure, or the national grid code for the territory. Never compare a result obtained under IEC 60156 with a limit written for ASTM D1816, or the reverse - a 40kV reading can be acceptable under one method and marginal under the other. The practical solution is a tester that stores both procedures as selectable presets, so the method, gap and electrode type travel with every recorded result.
Q2: Why do 60kV, 80kV and 100kV testers exist - does a higher voltage range give a better measurement?
Answer:
The voltage class of the tester defines the ceiling of what it can measure, not the quality of the measurement. New oil and oil from high-voltage assets can break down well above 70kV in the 2.5 mm gap, and a 60kV set simply cannot resolve those values: the test either stops short or the operator is forced to reduce the gap, which invalidates comparison with the standard. A 100kV set clears the range needed for acceptance testing of new oil and for 220kV and above assets, while 60kV and 80kV sets cover the in-service population of distribution and medium-voltage transformers.
Choose the range from the highest value you expect to see, then add margin for the voltage rise during the Ramp Rate and for repeated breakdowns at altitude or in cold weather. Buying a set that sits at its limit produces truncated results and stresses the internal transformer continuously; buying far above the need adds weight and cost without improving accuracy. The selection table on the following page maps each range to its application.
Q3: How does Ramp Rate affect the measured breakdown voltage, and what should be set?
Answer:
The Ramp Rate is the speed at which the test voltage rises across the gap. A slow rise gives the oil time for impurities to migrate and align with the field, so breakdown occurs at a lower voltage; a fast rise can overshoot the true inception value because the trip circuit reacts after breakdown has already started. Both standards fix the rate for exactly this reason, typically around 2 kV per second, and the tester must hold that rate independent of load and mains fluctuation.
Set the rate from the selected standard and leave it there for the whole series. Where a variable rate is offered, use it only for investigative work - for example, a deliberately slow rise when studying particle behaviour - and record the rate alongside the result. Inconsistency between two laboratories testing the same oil is more often a difference in Ramp Rate than a difference in the oil.
