The heart of earth fault monitoring
Earth fault monitoring is the foundation of good electricity
small
Early identification of anomalies in electrical installations
Smarter electricity quality
Early identification of anomalies within the electrical installation. The system sends alarms when increasing leakage currents exceed preset alarm values.
Around the clock monitoring
The system measures leakage currents continuously. By controlling an increasing earth fault in the outgoing groups, the risk of accidental outages is reduced.

By identifying weaknesses early, they can be addressed before they become a problem. This makes it easier to take decisions on actions and investments.
Scalable
IsoBase can be expanded with additional groups or to take monitoring further out in the plant. Monitoring can be carried out down to 1-phase group.
Increased safety
Get automatic control of rising leakage currents. Alarm levels in mA send alerts to operating personnel. The system instantly locates where in the plant the fault is.
Smart power quality
In today’s technologically advanced society, there are benefits for everyone to use a ground fault monitoring system. Megacon’s earth fault monitoring system allows you to monitor the leakage in a group continuously and with extreme accuracy. It is not only a reliable solution, it is also an effective tool for preventive maintenance. We at Megacon AB are dedicated to delivering power quality and energy management that ensures the safety and efficiency of your five-wire system. By monitoring groups and isolating potential risks, our products and services help maximize performance and minimize downtime. Take control of your system and avoid costly outages with Megacon’s earth fault monitoring system.
Round-the-cycle monitoring
As soon as a ground fault is detected, the system indicates it with an alarm signal. The level of alarms and warnings can be set as low as desired to minimize the risk of damage. The system also shows where in the installation the earth fault has occurred so that action can be taken quickly and safely.
Commercial properties
The working environment is affected by the quality of the electricity networks. A well-functioning five-conductor system minimizes both magnetic fields from the electricity grids as well as data disturbances due to unclean electricity environment. Monitoring earth faults and solving the problems that arise are prerequisites for maintaining functioning electricity grids.
Hospitals
In the healthcare sector, problems can occur if a conventional earth fault breaker triggers. Megacon has products that monitor one or more groups of indications eg. in a treatment room or in an emergency room. You can read more about our installations in hospital environments here:
Industry
The monitoring of earth faults is a prerequisite for leading a preventive entertainment work in five-conductor systems in industry. Detecting the onset of weakening isolation and fixing the problem during a planned downtime can help save a lot of money.

Workshop environment
At one workshop, the Megacon earth fault monitoring system gave an earth fault indication on certain occasions, but they did not really understand why. When training the system on earth fault monitoring, a real fault occurred and they checked which machines were connected to the group that was giving the alarm.
It was quickly established that it was a cable that had been chafed and corroded by oil and thus lost its full insulation, which caused creeping currents. This meant that in this situation there was only an alarm on the alarm panel, the earth fault current was lower than 300mA, and no impact on the machine and surroundings had occurred.
Summary of the visit:
There was a planned stop of the workshop machine and the replacement of the cable. In this case, there was no downtime during an already full work shift.
A shutdown of this workshop machine would have affected the entire production line and thus caused high downtime costs and extended delivery times.
What could have happened in the event of a real short circuit of the cable would probably have been much worse. We are pleased to see that monitoring with our products provides real security and quality.
