At the same time, all of the above is also true in industrial environments with CNC machines such as water jets, lathes, milling, punching, and so on. Insulation monitoring devices (IMDs) are used for easy application in IT power supply systems in metallurgy, civil engineering, shipbuilding, hospitals and transportation environments.
How the isolated transformer works:
isolater panel Due to the low impedance, it transmits power well in the designed range and also due to proper insulation and lack of electronic connection between the primary and secondary completely prevents the passage of AC voltage. The transformer in the frequency range of 50Hz practically creates high impedance for high frequencies and noise caused by the devices in both directions. Saturation of the transformer core will also prevent the passage of high frequencies due to lightning or any other factor.
Lack of electronic communication between primary and secondary practically eliminates the connection between earth and secondary, and in the isolated or secondary part, there is no concept of phase and zero, and none of the wires will cause electric shock. In places where there are severe disturbances and noises in the network, the SINGLE SHIELD and SHIELD DOUBLE types of this transformer can be used. ISOLGUARD Insulation Monitoring Devices are equipped with a display that shows the exact numerical values of the insulation resistance and allows monitoring the change of insulation status before the origin of the first ground fault.
Isolation panel safety check:
Immediate inspection of the network condition, continuous monitoring of the ground insulation level
Early detection of defective devices with immediate marking by insulation monitoring device
Less risk of electric shock to the operator and higher fire safety
To prevent losses and shut down production, in case of the first defect, the operation can be continued.
