10KV IR Tester S1-1068

With class-leading noise rejection of 8 mA – twice that of most comparable instruments – and enhanced software filtering that has four user-selectable options, Megger’s S1 series of 5 kV, 10 kV, and 15 kV DC insulation resistance testers deliver dependable results in even the most severe of electrical environments, including high voltage transmission and distribution substations. Other innovative features include provision for remote control via a fully isolated USB port, which makes the instruments ideally suited for use in production environments, and internal storage for date- and time-stamped results. Stored results can be recalled to the display, downloaded via a Bluetooth wireless link, or accessed via the USB port.

Compact and lightweight, the S1 insulation resistance testers feature a tough dual-case design and, with the lid closed, they have an IP65 ingress protection rating. They offer timed insulation resistance (IR), dielectric absorption ratio (DAR), polarisation index (PI), dielectric discharge (DD), step voltage (SV) and ramp diagnostic tests, and also have a dedicated voltmeter function.To ensure that testing is never delayed through lack of power, S1 insulation testers incorporate rapid-charge Li-ion batteries. This gives up to 4.5 hours for the S1-1068. With just 30 minutes of charging from flat, the batteries give around one hour of testing time, and it’s also possible to operate the instrument from an AC supply even if the battery is completely  Megger S1-1068  have a high short-circuit current of 6 mA to ensure rapid charging of items under test and the S1-1068 has a CAT IV 600 V safety rating at altitudes up to 3000 m.

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


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.


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!

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.
