Earth fault monitoring & Insulation monitoring - Superintend®

With our earth fault monitoring system, you can monitor your installation from any Internet-connected computer. This is because each control unit has a built-in web server that you can log into from your regular web browser.

The system also has a mobile-friendly interface, so you can monitor more easily via your smartphone or tablet. In our new series of control units, you can choose from 8, 32 or 64 measuring points. Of course, you can also combine several units into larger systems.

An earthed electrical system should be continuously monitored to detect faults and generate alarms for the following:

• Cable fault (for example a pinched cable)
• Interconnections of neutral and protective conductors
• Connection of faulty appliances
• Deteriorating insulation
• Slowly growing leakage currents, not sufficient to trip fuse or circuit breaker

Earth fault monitoring is a prerequisite when you want the highest possible fire and electrical safety. However, for monitoring to be effective, it must first and foremost be continuous, i.e. it must test all measuring points all the time. The equipment should also have a memory function that can display the time, size and duration of occurring earth faults.

With this function, you can easily locate temporary ground faults, for example. Moreover, you should not have to be parked in front of an instrument all the time. This requires the possibility of remote control and analysis - of course via PC, for those who wish. Finally, you should be able to easily assemble the equipment and not have to calibrate the system after installation. We believe that all of the above are basic requirements you can set for an earth fault monitoring system.

So how many people can meet the requirements?
The answer is Superintend^®.

That's why you should choose Superintend if you want an advanced system with unique analysis capabilities. In return, you get a safe electrical system that reduces the risk of fire and personal injury.

Isolation monitoring - Superintend^® reduces the risk of fire and personal injury.

The advantage of an IT network is that the fault currents are considerably lower in the event of an earth fault or insulation fault, compared with conventional directly earthed networks (e.g. five-wire networks). This is why IT networks are often used in applications where outages are to be avoided.

A common area is in healthcare, where in so-called Group 2 rooms with, for example, life-support equipment, you naturally want to avoid interruptions.

Another area is in industry, where, for example, the process industry wants to avoid interruptions in critical processes

The equipment continuously checks the insulation of the isolated power system by emitting a test signal pattern with two sinusoidal voltages. The signal gives rise to a small injection current that passes through the insulation resistance and capacitance to the PE potential. Using advanced measurement techniques, the equipment then analyzes the resistance and capacitance values.

This test system works in all kinds of power systems, from DC to AC and meets the response times of IEC 61557-8. The measurement method is also well suited for systems with high capacitance and resistance simultaneously. A further advantage is the display of real capacitance.

• Visual user interface and easy installation
• Automatic detection of network impedance and capacitance (subharmonic distortion)
• Monitoring the load and temperature of the isolating transformer - potential-free contact
• Same system for both industrial and medical applications
• Optional modules for remote monitoring of insulation and transformer
• Possibility to connect monitoring devices for the measurement of protective soil
• Replaceable microSD card for analyzing history and error events
