Megger's 5 kV, 10 kV, and 15 kV DC insulation testers set the industry standard for insulation resistance testing. Designed for diagnostic testing and maintenance of high-voltage electrical equipment, these rugged, portable instruments offer unparalleled performance, safety and reliability for OEMs, industrial companies, electrical contractors and utility providers.
Whether conducting routine maintenance or advanced diagnostics in the most demanding applications, Megger's insulation testers deliver the precision and dependability required for confident decision-making and effective asset management.
There is one instrument in the Essential range, the MIT515. This is a 5 kV product that provides all of the most commonly used tests: standard insulation resistance measurement, dielectric absorption (DAR) and polarisation index (PI). Essential instruments have no onboard data storage and a maximum burn/charge current of 3 mA. They are ideal for simple go/no-go testing but are not limited to this.
The Advanced range has three instruments: MIT525 (5 kV), MIT1025 (10 kV) and MIT1525 (15 kV). These differ only in their maximum test voltage. As well as the tests provided by the Essential instrument, these offer dielectric discharge (DD), step voltage (SV), ramp voltage and, when used in conjunction with PowerDB software, polarisation/depolarisation (PDC) tests. They have extensive onboard data storage and can transfer test results to PowerDB and CertSuite Asset via a wired USB connection. Maximum burn/charge current is 3 mA. Advanced instruments are the right choice for users who need more versatility than is provided by Essential products, but not the special performance enhancements of the Expert range.

Featuring instruments designed specifically for users with the most demanding requirements, the Expert range includes the S1-568 (5 kV), S1-1068 (10 kV) and the (S1-1568). These instruments differ only in their maximum test voltage. Expert instruments provide all the facilities of the Advanced products but incorporate enhanced software filtering and noise rejection of 8 mA to give reliable results even in extreme electrical environments up to 1,000 kV. Expert instruments have a maximum charge/burn current of 6 mA and support Bluetooth® wireless connectivity.
All Megger 5 kV, 10 kV and 15 kV insulation resistance testers incorporate Megger's unique and patented PI PredictorTM technology. With this, a PI test that used to take at least ten minutes can now typically be performed in five minutes or even less. This delivers significant time savings, especially when PI tests need to be performed separately on three phases.
Many insulation resistance testers have guard terminals to minimise the effects of surface leakage, but poorly implemented guard terminals can reduce measurement accuracy. The guard terminals in all Megger 5 kV, 10 kV and 15 kV instruments are free of this problem, ensuring accurate results even with high surface leakage.
First, decide on the type of testing you need to perform. If it's routine go/no-go testing and you don't need data storage, an Essential instrument will likely be a cost-effective choice. Consider an Advanced instrument for more versatility and/or internal data storage. And if working in extremely electrically noisy environments or need high charge/burn currents, an Expert instrument will be right. Having decided on Essential, Advanced or Expert, choose the instrument that will deliver the maximum test voltage needed.
