Insulation monitoring devices for early signalling of an earth fault in the IT systemUnearthed power supplies have an invaluable advantage – a first earth fault does not lead to shutdown, operating processes are not interrupted. This is why IT systems with insulation monitoring are used wherever a maximum of security and reliability is required. The heart of every IT system is the insulation monitoring device ISOMETER®.

Functionality:The insulation monitoring device ISOMETER® continuously monitors the insulation resistance between system and earth and signals immediately if the measured value has fallen below a certain value. This early information leaves enough time to eliminate the cause of the fault – before a critical operating state occurs!

ISOSCAN® insulation fault location systemFor unearthed power supplies (IT systems)

Stationary and portable equipment for fast localisation of insulation faults.ISOSCAN® is based on the insulation monitoring device ISOMETER® with an integrated locating current injector.

Functionality:If an insulation fault occurs, insulation fault location starts automatically. The locating current injector generates a locating current signal which flows back via the faulty current path and the PE conductor. All measuring current transformers in this circuit register the locating current signal and report it to the corresponding insulation fault locators. The assignment of measuring current transformer/output enables the electrician to locate the fault easily, quickly and safely on screen.

Insulation monitoring device with integrated

insulation fault location system

Insulation fault location system

Insulation fault location in extensive IT systems is time-consuming and costly. The solution: insulation fault location systems (EDS).

For installations with subordinate outgoing circuits, portable insulation fault location systems are available. With a measuring clamp the cables of the respective circuits are covered, locating current signals are checked and the faulty circuit or location is determined.

LINETRAXX® residual current monitorsFor earthed power supplies (TN and TT systems)

RCM, RCMA residual current monitors for earthed power supplies (TN/TT systems)Residual current monitors are used to monitor electrical installations for residual or fault currents, display the currently measured value and report when adjustable response values are exceeded. They can optionally be used for signalling and/or switching.The main areas of application are where a disconnection is not desirable or problematic due to the electrical load structure, e.g:

n Fire and property protection in industrial and functional buildings

n UPS systems

n Cooling systems, air conditioning systems

n Variable-speed drives

n Lighting circuits

n Medical facilities

n Safety circuits

n EDP systems and much more


n Significant cost reduction through higher availability and minimised maintenance costs

n Increased fire and property protection

n AC/DC sensitive versions for monitoring alternating currents, pulsating and smooth DC fault currents

n Independent of waveform by true RMS measurement (TRMS)

must be continuously monitored, the location of the faults quickly localised and the service personnel must be comprehensively informed. The solution to this problem is the multi-channel residual current monitoring system RCMS460/490. The system records the currents sensitive to alternating, pulse or universal current as a true RMS value. The measured values are stored in the history memory and data logger and are available for evaluation. Up to 1080 measuring points can be monitored, whereby the maximum query time for all channels is less than 200 ms. This makes it easy to monitor even time-critical applications with shutdown. Information is exchanged between the devices via a time- and cost-saving RS-485 interface. A connection to higher-level systems via Ethernet or other field bus systems is easily possible with gateways. For installation in final circuits, the RCMS150 with 6 AC/DC sensitive channels extends the RCMS product portfolio.

Residual current sensors for AC charging in IC-CPDs (mode 2) and charging stations/wallboxes (mode 3).Residual currents are continuously monitored during AC charging, so that the charging process is interrupted as soon as there is any danger to persons.Due to their compact design, the residual current sensors are ideally suited for space-saving use in any charging infrastructure.


n Cost-effective solution, as it can be used with an RCD type A. No RCD type B required.

n Space-saving: integrated electronics and converter

n Can be combined with various measuring current transformers

n Compact construction and robust design

n Implemented self test function

n High insensitivity to external interferences

Residual current sensor technology for AC charging

Insulation monitoring devices for direct current (DC) charging (mode 4)DC charging stations are designed as unearthed systems and must therefore be equipped with an insulation monitoring device. Due to the high currents, the safety of persons plays a very important role. ISOMETER® can be used in both systems:

n Combined Charging System (CCS)

n CHAdeMO standard Convincing advantages:

n For DC charging systems up to DC 1000 V

n Monitoring of the complete charging circuit: from the charging station to the electric vehicle

n Active measurement method according to IEC 61557-8

n Basic parameterisation 100/500 kΩ (error/warning)

n Modbus RTU interface

n Signal relay

Web-based software solution POWERSCOUT®

POWERSCOUT®Find out today what won't happen tomorrow

Moisture, deterioration, dirt, mechanical damage or faults due to the impact of current, voltage and temperature cause malfunctions in every electrical installation. The web-based software solution POWERSCOUT® helps you detect malfunctions at an early stage and eliminate the causes in an economically reasonable way. This guarantees high installation and operational safety and reduces costs.

Analysis – as individual as your system– as simple as possible

Predictive maintenance prevents downtimes, reduces costs and staff deploy-ment. POWERSCOUT® informs you about the condition of your electrical installation at all times, since the meaningful visualisations with flexible dashboards can be retrieved via any display device: smartphone, laptop, computer. On request, POWERSCOUT® sends you graphically processed reports at specified intervals.

Continuous monitoring instead of random tests

Manual data acquisition is time consuming, error-prone and only provides random results. POWERSCOUT® gives you an insight into the entire data of your installation at any time, since all measured values are automatically and continuously saved. Your data is stored reliably and remains available for years.

Basis for periodic verification

The automated POWERSCOUT® report on residual currents forms the basis for measuring without switch-off by means of periodic verification. In order to maintain the correct status for electrical installations and stationary electrical equipment, periodic verification must be carried out.

This can be ensured, for example, by means of continuous monitoring of the installation carried out by qualified personnel. In this case, it would be smart to rely on continuous monitoring with multi-channel residual current monitoring systems (RCMS) and an evaluation (CP700) adapted to the system. The automatic POWERSCOUT® reports based on this monitoring enable the qualified person in charge to adjust the time limits for the insulation test within the context of periodic verification.
