Description

The MJÖLNER™ is designed to measure the resistance of circuit breaker contacts, bus-bar joints, contact elements in bus-bars and other high-current links. The product has been designed with safety, ease of use and versatility in mind. The micro-ohmmeter conducts true DC ripple free current and can be used anywhere to measure a low resistance value with high accuracy. With MJÖLNER it is possible to make measurements according to the DualGround™ method. This means that the test object will be grounded on both sides throughout the test giving a safer, faster and easier workflow.
Choose the MJÖLNER with excessive power resources for demanding applications, superior measurement accuracy and when 300 Amp continuous is required. The lightweight and rugged suitcase design makes MJÖLNER an excellent choice when you need a portable solution in the field. When the case is closed, the product can withstand the impact of water, dust or sand – it even floats. Two optional accessories are; a remote control and the PC software MJÖLNER Win that is compatible with IPS–CBEX and have export functions for tables to Microsoft® Excel®.


Applications

MJÖLNER test system is designed to serve a number of applications. The most common are contact resistance measurements of low-, medium- and high-voltage breakers and also at bus-bar joints, and other high current links. The contact resistance measurements concerning breaker testing are particularly called for in the following standards: ANSI C37.09-1979 (5.14), IEC 1208 and IEC 694 (6.4). If the contact resistance is too high this will lead to power loss and temperature rise, which often leads to serious trouble. To avoid such problems, it is necessary to check the resistance at regular intervals.
