Micro-ohmmeter MOM600A

Adiradh offers the Megger MOM600A 600 A Micro-Ohmmeter for low-resistance and contact-resistance testing in electrical power equipment. Moreover, the instrument delivers up to 600 A DC test current. Therefore, technicians can use it to measure contact resistance in high-voltage circuit breakers, disconnecting switches, isolators, knife-contact fuses, busbar joints, and line joints. In addition, the MOM600A uses separate measurement cables with its high-current cables. This arrangement supports low-resistance measurement at electrical connection points. Furthermore, Megger designed the instrument for field use across a wide range of temperatures. As a result, technicians can use the MOM600A in different outdoor and industrial environments. The unit also includes flexible cables and a rugged transport case. Moreover, its compact and robust design supports practical field testing. The MOM600A uses mains power and does not provide built-in data storage or communication. Therefore, it focuses on high-current contact-resistance measurement for power equipment maintenance and testing.

Overview

The Megger MOM600A is a 600 A micro-ohmmeter designed for high-current low-resistance testing. Moreover, it helps technicians measure contact resistance in high-voltage switching equipment and electrical joints. The instrument provides a maximum DC output current of 600 A. Therefore, it suits applications that require higher test current than the 200 A MOM200A. In addition, Megger specifies the MOM600A for high-voltage circuit breakers, disconnecting switches, isolators, knife-contact fuses, busbar joints, and line joints. Furthermore, the instrument uses separate measurement cables along with flexible current cables. This cable arrangement supports contact-resistance measurement at the test object. The MOM600A also uses mains power for operation. However, the product does not include data storage or communication functions. Consequently, users can focus on direct field measurements without onboard result management. Moreover, Megger provides the complete unit with a sturdy transport case.

About Product

The Megger MOM600A uses high-current DC injection for low-resistance contact measurement. Moreover, its maximum output current reaches 600 A DC. Technicians can therefore apply a high test current when checking electrical connections in power equipment. The instrument targets contact-resistance measurements in high-voltage circuit breakers, disconnecting switches, isolators, knife-contact fuses, busbar joints, and line joints. In addition, the MOM600A uses separate measurement cables to measure the test connection. This approach supports low-resistance measurement by keeping the measurement path separate from the high-current path. Furthermore, Megger designed the instrument with a compact and robust construction for field work. The complete system includes highly flexible cables and a rugged transport case. Therefore, technicians can transport the equipment between substations and other test locations. The MOM600A uses mains power, while Megger lists no onboard data storage or communication for this model.

Technology & Benefits

The MOM600A applies high-current DC testing to evaluate low-resistance electrical connections. Therefore, technicians can use it to check contact resistance in circuit breakers, disconnectors, isolators, fuses, busbar joints, and line connections. Moreover, the instrument can deliver up to 600 A DC, which supports applications that require higher test current. Megger’s product comparison data lists a 0–600 A test-current range and a maximum test time of 15 seconds at maximum current. In addition, the same data lists 100 A as the maximum continuous current. Furthermore, separate measurement cables help the instrument measure the resistance of the test connection while the main cables carry the high test current. The rugged construction also supports field work in different temperature conditions. Moreover, the supplied flexible cables simplify connection to test points. Finally, the transport case helps technicians move the complete test set between locations.
