Insulation Monitoring Devices

For more than 60 years, Dipl-Ing W Bender GmbH & Co KG offers measuring, monitoring and protective systems to monitor the electrical safety of machines and systems. The A-Isometer range of insulation monitoring devices is meant for unearthed power supplies (IT systems). Unearthed power supplies offer an invaluable advantage – a first earth fault does not cause tripping and the system thus continues to operate uninterrupted. Consequently, IT systems with insulation monitoring are used in situations that call for maximum safety and reliability. At the heart of any IT system, there is an A-Isometer insulation monitoring device. This continuously monitors the insulation resistance between the supply system and earth and immediately signals when a specific value is undershot. This early warning system provides sufficient time for the cause of the fault to be eliminated before a critical operating state has a chance to develop.
