Megger MJOLNER 600 Micro-Ohmmeter

The Megger Mjolner 600 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 the Mjolner 600 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 Mjolner 600 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 600 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. Optional accessories are a remote control and the PC software Mjolner Win with export functions for tables to Microsoft® Excel. The following table demonstrates how important low resistance is at high currents: Current Contact Resistance Power Loss 10 kA 1 mΩ 100 kW 10 kA 0.1 mΩ 10 kW 1 kA 1 mΩ 1 kW 1 kA 0.1 mΩ 100 kW FEATURES Specifically designed for measuring contact resistances in circuit breakers, disconnecting switches, bus-bar joints, and other such devices. Safer testing using the patented DualGround™ technology to test circuit breakers with both sides grounded. Fully automatic testing- microprocessor controlled. Wide measuring range and test currents.
