What is Bender IR470LY-40 A-Isometer?
The Bender IR470LY-40 is a special device for insulation monitoring in ungrounded AC, DC, and AC/DC systems. The unit monitors insulation resistance between conductors and earth continuously and notifies users of insulation deteriorations or failures. In contrast to basic ground-fault detection, the IR470LY-40 provides continuous and anticipatory monitoring even under working leakage capacitance.
This clever device facilitates the premature detection of electrical dangers, allowing engineers, electricians, and maintenance personnel to take corrective action before a failure or risk.
