Sistema 380V
380V System
❗All laser machines and manual devices must be installed with a voltage stabilizer, as the laser source is extremely sensitive to voltage fluctuations!
❗Grounding must have resistance no higher than 1.5 Ohm, otherwise the height sensor may malfunction.
Most laser machines are built on 380V with separate neutral and ground TN-S.
The TN-C-S system can be used, but if the PEN wire from the substation burns out, the entire system will be exposed to dangerous voltage for humans.
GOST R50571 and the updated edition of PUE contain requirements for power supply systems based on TN-S for all critical facilities, as well as buildings under construction and major renovation, ensuring a high level of electrical safety. Unfortunately, the widespread adoption and implementation of the TN-S system is hindered by high costs and the orientation of Russian power engineering toward four-wire three-phase power supply schemes.
