Used with Megger MFT-X1 multifunction installation testers, the EVX100 adaptor provides all the functions needed for automated and manual testing of single- and three-phase Mode 3 electric vehicle charge points rated at up to 22 kW. Unlike other adaptors, the EVX100 mounts directly onto the MFT, which means it provides a fully integrated solution that doesn’t need inconvenient interconnecting cables. 

Another unique benefit is that the EVX100 is directly controlled by the MFT-X1, which makes it easier and faster to use. In addition, direct control reduces the possibility of making incorrect test selections. The EVX100 also confirms that the mode set on the charger is correct for the test being performed.

To make testing even more convenient, the EVX100 offers automated testing, which means that you will no longer have to manually cycle the charge point through numerous CP states every time a test trips a protective device such as an RCD or RDC. As protective devices are often fitted in locations at a considerable distance from the charge point, this feature can potentially save a lot of walking and valuable time.

The EVX100 is powered by a high capacity internal battery, which can be recharged quickly via a standard USB-C charging port. This means you won’t need mains cables with various types of plugs. Just two charger connectors – Type 1 and Type 2 – will almost certainly cover all of your testing requirements, with type 2 supplied as standard. And, if you’re a user of CertSuite Installation software, you can produce customised test certificates in real-time with just a couple of clicks.

EVX100 Datasheet

• Capable of testing transformers up to 1000 MVA
• DC test current up to 50 A maximum
• Integrated demagnetisation feature
• Computer control and internal data storage
• Validates proper operation of on-load tap changers
• Protected against accidental current lead disconnection (through potential leads)

The MTO250 50 A transformer ohmmeter is a line-operated, field-portable instrument designed specifically to measure the resistance of all types of magnetic windings safely and accurately. It tests transformers, shunt reactors, and rotating machine windings, and it performs low resistance measurements on connections, contacts, and control circuits.

The dual set of potential inputs enables the resistance measurement of either two primary, two secondary windings, or of a primary plus a secondary winding simultaneously. This dual reading, dual injection characteristic, is a highly efficient method of completing tests in a timely manner.
