Megger supplier in Romania
Insulation and electrical installation test instruments
Founded in 1889 · Headquarters: Dover, United Kingdom
Who is Megger and what does it make?
Megger is a British manufacturer of electrical test instruments, with roots going back to 1889 and headquarters in Dover. The company makes insulation testers, cable test systems, multifunction testers, motor testers and transformer test systems, used by electricians and maintenance engineers to verify electrical installations. From the Megger range we can quote both portable instruments for electricians and more complex systems for utilities and industry.
Megger offers electrical test instruments, with an emphasis on insulation testing — the company name has even become a generic term for the insulation tester in technical English. The range includes insulation testers such as the MIT525 and MIT1025, a VLF Sine cable test system, the MFT-X1 multifunction tester, the ADX motor tester and the TRAX system for testing transformers. The portfolio covers portable instruments and systems for testing cables, motors and transformers.
For the Romanian market, Megger instruments are relevant to electrical maintenance companies, power distribution companies and licensed electricians who need insulation tests, cable tests or periodic checks of installations according to the technical norms.
What do we supply from the Megger range?
| Product | Description |
|---|---|
| MIT525 / MIT1025 Insulation Testers | Portable insulation testers, with a different test voltage for each model in the series, used to check the insulation resistance of cables and electrical installations before energising or during periodic maintenance. Instrument used by electricians and maintenance engineers for testing the insulation of motors, cables and electrical equipment. |
| VLF Sine Cable Test System | Medium-voltage cable test system using a very low frequency (VLF) signal, used to check the integrity of the insulation of buried or installed cables without needing the standard alternating-current test voltage. Useful for the acceptance of new cables or for diagnosing faults on existing cables. |
| MFT-X1 Multifunction Tester | Multifunction tester for verifying electrical installations — continuity, insulation resistance, loop impedance and other tests required at the acceptance or periodic inspection of an electrical installation. Basic instrument for licensed electricians carrying out checks according to the technical norms. |
| ADX Motor Tester | Dedicated tester for diagnosing electric motors, used in preventive maintenance to identify insulation or winding problems before they lead to motor failure. Relevant for facilities with electric motors that are critical to the production process. |
| TRAX Transformer Test System | System for testing power and distribution transformers, used by electrical utilities and maintenance companies for the periodic checking of transformers in electrical substations. Covers several types of transformer-specific tests in a single piece of equipment. |

How do we supply Megger in Romania?
We hold no stock of our own of Megger instruments; we work from the technical documentation of the British manufacturer and confirm real availability with each request received. We bring in the instruments to order through EU supply channels, usually within 1–4 weeks of order confirmation. For a correct quotation we need the exact model requested, the test voltage required and, for cable or transformer systems, the type of equipment being tested. We do not promise permanent availability from stock for all models in the range, especially for more complex systems such as TRAX.
Calibration and after-sales service for Megger instruments are handled by the manufacturer's service network.
Frequently asked questions about Megger
What is the difference between the Megger IDAX300 and IDAX350 analysers?
The IDAX300 is the basic version of the insulation diagnostic analyser using dielectric response, used to assess the condition of the insulation of transformers and other high-voltage equipment. The IDAX350 belongs to the same family, with additional measurement functions and a wider range of available tests. The choice between variants depends on the complexity of the diagnostic tests needed in the laboratory or substation concerned.
What is the Megger TRAX system and what accessories does it use?
TRAX is a multifunction instrument able to perform more than twenty different electrical functions on transformers and substation equipment, from a single hardware platform. Accessories such as the TDX120 extend power factor testing to higher voltages, and the TSX300 and TSX303 switch boxes automate phase selection during repeated measurements. The exact configuration depends on the type of tests planned for each substation.
Do you supply Megger equipment in Romania?
Yes, we bring in Megger testers and systems on request, starting from the model code supplied, without a reserve of our own kept on the shelf. To order, usually 1–4 weeks from order confirmation (Megger). We recommend stating the rated voltage of the equipment being tested to confirm the compatibility of the chosen variant.
What should I specify for a quotation on a Megger insulation tester?
The test voltage required is important, for example five, ten or fifteen kilovolts, as is the type of equipment to be checked: cable, motor or transformer. It also matters whether a portable version from the MIT200 or MIT300 series is wanted, or a more complex laboratory system such as TRAX. The test standard applicable to the installation helps in choosing the correct model.
How do I request a Megger quotation?
Send the Megger code from the nameplate and the quantity; we reply in English with availability and the lead time written in the quotation.
