The special extra for increasing the reliability of your electrical installations In order to achieve high reliability and to avoid costly shut-down periods of electrical installations, it is necessary to recognize insulation faults at an early stage – before interruption to operation occurs. For this reason, unearthed systems (IT systems) with insulation monitoring are used for the power supply of essential electrical installations and loads. The A-ISOMETER® provides the necessary advance information. Fast localisation and elimination of insulation faults is required by DIN VDE 0100-410 (VDE 0100-410): 2007-06 chapter 411.6.3.1 and IEC 60364-4-41 chapter 413.1.5.4 "It is recommended that a first fault be eliminated with the shortest practivable delay". The EDS system is a modular system ideally suited for this task. There is a variety of application fields for EDS systems.
They are used for main circuits and control circuits for example in power plants, hospitals, shipbuilding, traffic engineering, industrial plants, paper industry, oil and natural gas industry, mining, open-cast mining, rolling mills, mechanical engineering, and in a lot of other sectors.
Example of application:
Advantages of the insulation fault location system EDS
- No disconnection of the electrical installation, insulation fault location is carried out during operation.
- Fast localisation of the faulty sub circuit.
- Details about the location of the fault are indicated at a central point.
- Reduced maintenance and repair costs.
Different types of measuring current transformers are available for application in insulation fault location systems EDS470 to meet the requirements of the individual electrical installation. All measuring current transformers listed in the table below are highly sensitive and convert even small residual currents into evaluable signals. The measuring current transformers are connected to the evaluator by two connecting leads. Particular attention shall be paid that all current-carrying leads of the respective subcircuit are passed through the current transformer with the exception of the PE conductor.
