Udstyr til lokalisering af isolations fejl

In complex industrial systems, the localisation of insulation errors can be expensive and time-consuming. The insulation error search system from DOLD allows an automatic and fast localisation of faulty electrical circuits in complexly insulated AC/DC networks (IT systems) and this increases reliability and system availability. Thanks to the low maintenance costs and the avoidance of interruptions in operation, the investment costs for the DOLD insulation error search system are amortised quickly.
