Isometers

Isometers, also known as insulation monitoring devices (IMDs), are used to continuously monitor insulation resistance in electrical systems. They detect insulation faults early, helping prevent equipment damage, electrical hazards, and unplanned downtime.

At Drive Outlet Megastore, we stock a wide range of isometers from trusted manufacturers including Bender, ABB, Siemens, and other leading automation brands. Our selection includes insulation monitoring devices designed for industrial systems, motor control centres, and critical power applications.

Isometers are commonly used in inverter drive systems, ungrounded power systems (IT systems), medical installations, industrial machinery, and critical infrastructure where continuous insulation monitoring is essential. They help detect ground faults early and ensure system safety and reliability.

We supply isometers with various monitoring ranges, alarm outputs, communication interfaces, and mounting options to suit different applications and system requirements. If you’re unsure which isometer is suitable for your installation, our technical team can help you select the correct insulation monitoring solution.
