Get your MITs on Megger’s tough new insulation testers!
Capable of providing accurate measurements up to 10 TΩ for 5 kV versions and 20 TΩ for 10 kV versions and having facilities for IR, IR(t), PI, DAR, DD, SV and ramp tests, Megger’s new high-voltage insulation resistance testers (IRTs) offer exceptional versatility in a compact, rugged and light unit that weighs little more than half as much as its predecessors.
■ Small, light and sophisticated
|The instruments also provide enhanced productivity - they can be used from an AC source even when their internal rechargeable battery is fully discharged – and they are capable of delivering dependable results even in noisy electrical environments, such as electricity substations, with noise levels up to 3 mA.|
|Three new testers|
|Megger’s new IRTs are available in three versions:|
• The MIT515 5 kV insulation resistance tester is an entry-level 5 kV test set which offers insulation resistance (IR), timed insulation resistance (IR(t)), dielectric absorption ratio (DAR) and polarisation index (PI) test modes.
• The MIT525 5 kV insulation resistance tester, which is also a 5 kV unit, adds facilities for dielectric discharge (DD), step voltage (SV) and ramp diagnostic testing, as well as a large-capacity internal memory for storing time and date stamped test results, which can subsequently recalled to the display or downloaded to a PC via the instrument’s electrically isolated USB interface. Real-time output of results during tests is also supported.
• The MIT1025 10 kV insulation resistance tester offers the same facilities as the MIT525, but is a 10 kV unit.
The MIT515 and MIT525 allow tests to be carried out at five pre-defined voltages from 250 V to 5 kV, while the MIT1025 provides pre-defined test voltages from 500 V to 10 kV.
All models allow an additional user-defined ‘lock’ voltage to be set, a specific voltage range to facilitate repetitive measurements to guard against excessive test voltages being applied to sensitive equipment.
|Fast charge battery|
|Equally suitable for mains or battery operation, Megger’s new IRTs incorporate a user-replaceable rechargeable li-ion battery, which is automatically recharged when the instrument is connected to a mains supply. Discharged batteries take less than 2.5 hours to fully recharge and, when fully charged, they provide up to 6 hours of testing at 5 kV and up to 4.5 hours at 10 kV.|
|Other key features common to all of Megger’s new high-voltage IRTs include:|
The instruments are supplied as standard with test leads and clips, and a user guide on CD-ROM. Additionally, for the MIT525 and MIT1025, a USB cable is provided together with a copy of the Megger PowerDB lite software package, which is a convenient and versatile tool for storing, analysing and reporting test results.
