MEGGER

MEGGER is a British brand with a history dating back to 1889, when the first insulation tester was invented by Robert E. B. Crompton and Sydney Evershed. The company, now part of the Fortive group, specializes in electrical test and measurement equipment, particularly insulation resistance testers (megohmmeters), ground resistance testers, transformer test equipment, and power quality analyzers. MEGGER products are widely used in industrial maintenance, utility, and renewable energy sectors for commissioning, troubleshooting, and preventive maintenance of electrical systems. Key product families include the MIT series megohmmeters (e.g., MIT410-TC/3, MIT320, MIT481/2) designed for harsh environments with IP54 or IP65 ratings, test voltages from 50V DC to 10,000V DC, and measurement ranges from 0.01 ohm to 100 gigohm. The S1 series (e.g., S1-568/2, S1-1068/2) offers high-voltage insulation testing up to 10 kV with CAT IV 1000V safety ratings. MEGGER also provides specialized tools like the PVK330 photovoltaic kit for solar panel testing, the MTR105 motor rotation tester for three-phase systems, and accessories such as transformer testing leads (2008-60KIT2). All MEGGER instruments are built to international safety standards (IEC 61010) and carry CAT III or CAT IV ratings for use in high-energy environments. 3G Electric stocks over 100 MEGGER SKUs, including megohmmeters, insulation testers, solar analyzers, and phasing meters, with datasheets and logistics support for global shipment. The brand is recognized for its rugged construction, reliable measurements, and long service life in demanding field conditions.

Frequently asked questions

Common questions about MEGGER from 3G Electric.

What is the difference between the MEGGER MIT410-TC/3 and MIT320 megohmmeters?

The MIT410-TC/3 has a test voltage of 50V DC and measures from 0.1 megaohm to 1 gigohm, while the MIT320 offers selectable test voltages of 250V DC or 500V DC and measures from 10 ohm to 999 megaohm. Both have IP54 ratings and CAT IV 600V safety classification, but the MIT410-TC/3 includes USB connectivity for data transfer, whereas the MIT320 does not. Choose the MIT410-TC/3 for low-voltage insulation testing with data logging needs, and the MIT320 for general-purpose insulation testing at higher voltages.

What safety ratings do MEGGER insulation testers like the S1-568/2 have?

The MEGGER S1-568/2 has a CAT IV 1000V safety rating, meaning it is designed for use on primary supply levels, including overhead and underground utility lines. It also has an IP65 rating for dust and water ingress protection, making it suitable for outdoor and harsh industrial environments. The test voltage is 5,000V DC, and it measures insulation resistance from 100 kiloohm to 10 gigohm.

Can the MEGGER PVK330 solar analyzer kit be used for datalogging?

No, the MEGGER PVK330 photovoltaic kit does not include datalogging capability. It includes a DCM340 600A AC/DC clampmeter and an LCD display for real-time measurements of open-circuit voltage (up to 3V) and other solar panel parameters. For datalogging, you would need a different model or an external data logger.

What is the frequency range of the MEGGER MTR105 motor rotation tester?

The MEGGER MTR105 operates over a frequency range of 15 Hz to 400 Hz and a voltage range of 0 V to 600 V. It is designed for three-phase systems and has a CAT III 600V safety rating. This makes it suitable for testing motor rotation direction and phasing in industrial and commercial electrical installations.

Are MEGGER transformer testing leads (2008-60KIT2) compatible with all transformer turns ratiometers?

The MEGGER 2008-60KIT2 transformer testing leads are specifically designed for use with MEGGER transformer turns ratiometers. They are not guaranteed to be compatible with other brands. Always verify connector types and specifications with the manufacturer before use. These leads facilitate safe and accurate testing of transformer turns ratio.

Does 3G Electric supply MEGGER products?

Yes — 3G Electric (S) Pte. Ltd. supplies MEGGER products. We stock the MEGGER catalog and supply genuine factory-original products with full manufacturer warranty and technical support.
