About 220 volt

Hi ! Tell me....

Question about 220 volts in the power supply. if there is no land, how can this affect the device? can it break and the second question. if there is 120 volts between the ground and zero, how will this affect the device? can electronics burn out? It will be interesting if you share cases from practice.

  • Hi azrael,

    If your instrument is a 220 Volt and your electrical supply has been installed by an electrician, there is no difference in the operation/ reliability of the instrument.

  • Hi, James...

    Probably, Google translator no good trancled.  

    ISP MS broke at the institute. and we think that it’s about electricity. the device should have been grounded. but a voltage of 120 volts was applied to its body. could the detector power board burn out because of this? there are cases when, due to the fact that the device was live, the electronics burned out. so I’m interested in hearing from anyone else? expert opinion.there are cases when, due to the fact that the device was live, the electronics burned out. so I’m interested in hearing from anyone else? expert opinion.

  • Hi Abbey ! 

    Yes, you really helped. Thanks you. we have 120 volts between the ground and zero. between phase and ground 100 volts. between phase and zero 220 volts. 100 + 120 = 220 volts. I think that the phase voltage is divided between zero and ground. circuit somewhere. and that means that electronics could fail because of this. the device works, but not correctly. with mistakes.

  • Hi azrael, 

     

    Thanks for the clarification.  If the ground is not functioning at the outlet, the metal of the GC cannot be grounded.  This means anything that was touching the metal chassis of the GC could have been subjected to the full line voltage - lots of variables here, depending on the GC model and connected modules.  Most of the GC electronics (signal boards, heaters, sensors, etc) are running off DC generated by the transformer, so the full line voltage could have overloaded the electronics and blown fuses or other safety precautions built into the system.   There are primary fuses on the main power that are designed to blow and protect the system in high current failures, but they aren't necessarily designed to protect current flowing to the ground.  

     

    Difficult to assign a root cause for your troubles, but I would say a failed ground is usually a bad thing for GCs.   

     

    Are you seeing any signs of life at all on your GC?  

     

    Hope that helps - and also hope the ground to your site has been restored! 

     

    Best, 

    Abbey
