general information:
The isolation-guard IW1000 is used for insulation-monitoring in machines and systems with ungrounded voltage systems. The universal design allows the monitoring of all AC and DC systems.
Common insulation guards, working with pulse measuring mode, are running with fixed
pulse widths. For well operation, they must be adapted manually to the actual leakage capacity of the system. There are also insulation guards available, working with self adapting pulse width. However these devices need a long measuring time because the result will be at least available, when loading voltage will find its maximum (no more change in load voltage). With the time optimized measuring method of the IW1000, insulation resistance and leakage capacity will be calculated after 2-time constants. Therefor the reaction time of the IW1000 is very short.
