Various types of diagnostic insulation tests:

Spot Reading Test (IR )(IR(t)): The simplest of all insulation tests and the one most associated with lower voltage insulation testers; the test voltage is applied for a short, specific period of time and a reading is then taken

Time vs. Resistance Test (DAR): The concept of the time resistance test is to take successive readings at specified times during a single test.

Polarization Index Test (PI): The simplest implementation of the time resistance test for solid insulation, the PI Test requires only two readings followed by a simple division; the one-minute reading is divided into the ten-minute reading to provide a ratio. With “good” insulation, leakage current is relatively small and resistance rises continually as current decreases from the effects of charging and dielectric absorption

Dielectric Discharge Test (DD): While the other methods mentioned measure the currents flowing during the charging process, the DD test measures the current that flows during discharge of the test sample.

Step Voltage Test (SV): Since good insulation is resistive, an increase in test voltage will lead to an increase in current with a result that the resistance remains constant. Any deviation from this could signify defective insulation. At lower test voltages, say 500 V or 1000 V, it is quite possible that these defects might be unobserved, but as the voltage rises we reach a point where ionization can take place within cracks or cavities, resulting in an increase in current, and therefore a reduction in the insulation resistance.

Ramped Voltage Test: The ramped voltage test is endorsed in  IEEE95-2002 as part of the recommended practice for insulation testing of AC electric machinery (2300 V and above) with high direct voltage. When using this test method, the test voltage is gradually increased (ramped) at a set rate to a final level, which results in an increase in the current. Any variations in current compared to the increase in applied test voltage can provide useful diagnostic information about the condition of the insulation.

Choose an insulation tester?

Test Voltage

You should also base your voltage requirements on the rated voltage of the equipment you are working with, specifically whether or not you will be performing tests at or above rated, i.e. stress tests.Something to keep in mind is that pervasive insulation damage, such as moisture ingress, is revealed at any voltage; whereas mechanical damage usually requires a higher voltage for detection – capable of arcing an air gap.With 1 kV, 2.5 kV, and 5 kV models to choose from, this may be the most critical decision you have to make.

 Measurement Range

When  working in the realm of predictive maintenance, it’s critical to know exactly how your measurements change over time, specifically in the upper values of resistance.  Insulation testers allow you to test into the tera ohm range (TΩ) – giving you the capability to differentiate between elevated resistance measurements over time. It may be helpful to determine the exact insulation resistance values of your equipment when it’s new, and then choose a tester that can truly measure those values.

Power Source

Batteries are likely the most convenient,

Voltage Detection

Insulation testers  will detect unwanted voltage on the item under test

Display

Combine both  Analogue and LCD display capabilities in a single unit suggestable

 Ω/kΩ/GΩ/TΩ Ranges

Okay, these are commonly referred to as “continuity” and “resistance” ranges, which greatly enhance the depth of your testing capabilities. Ohm ranges can help you verify the integrity of circuits and connections, while kilohm ranges are helpful for identifying areas of insulation deterioration.

Guard Terminal

To eliminate certain components of leakage from measurements, should take the guard terminal into consideration.

Price

From a few  rupees thousands to several Lakhs , we have an insulation tester for every budget. Don’t let the price tag fool you either. Regardless of your budget, you’ll find a model that not only fits your testing requirements, but also offers a range of additional features too.

“Extra” Features

Newer models offer pre-programmed standardized tests, such as Polarization Index, Step Voltage, and Dielectric Discharge, along with calculation and storage of results, downloading capabilities, timed tests, leakage current measurements, and a “burn mode”.We recommend that if it fits your budget – go for it!

CAT Rating

 

In addition to the obvious performance specifications,instrumentation should also be evaluated according to various quality standards. Paramount among these is safety. One of the most recognized and respected safety standards has been established by the International Electrotechnical Commission (IEC) in EN61010-1:2001. This standard defines the requirements that test instruments must meet in order to be safe from arc flash and arc blast in specific environments. It is not enough to simply determine that an instrument is “CAT rated”, as it is commonly termed. The CAT rating must be understood, as it rigorously describes where in the electrical environment a given piece of
equipment can and cannot be safely employed.Megger MIT models ensure CAT rating applies to all terminals for safety purposes. Some instruments on the market todayare misleading.CAT Rating Guidelines .“CAT rating” is rendered in two parameters: one indicatingsystem level and the other specifying rated operating voltage.A designation of “CAT IV 600 V” means that the unit is safe to operate in any electrical environment up to and including CAT IV, on cable or apparatus rated up to 600 volts phase to ground.Beware of products that specify the CAT rating while failing to list the voltage level. This is incomplete information and the absence can be costly in terms of safe operation. The CAT rating defines the level of transient (spike or surge) that the instrument has been designed to withstand.


Testing Insulation Resistance of Rotating Machinery

In March 2000, the IEEE-SA Standards Board approved a revision of IEEE Std 43-1974 by the Electric Machinery Committee of the IEEE Power Engineering Society. This revision is IEEE Std 43-2000,
the “IEEE Recommended Practice for Testing Insulation Resistance of Rotating Machinery.” Changes made to the types of insulation used in electric rotating machines have resulted in different
insulation resistance characteristics, and therefore, required a substantial revision to the IEEE standard.
