How to commissioning ultra and flexy bts?
this would need some more detail , to be specific , and dependant on whether temperature, pressure , level or flow types. .. generally you should consider the impact if the system fails / would it result in a catastrophic situation arising, resulting a dangerous condition .? are there any fail safe emergency arrangements needed to continue cooling via pumps, or safety valves to control a pressure safely. is the new system about to be commissioned the right type for the application ? .. is installation - method the correct one.? are the sample and return pipelines set up correctly ? are there any intrinsic - safety requirements? should a valve stem or piece move during its operation ; will it clear any local objects or strike them resulting in a failure ? . is the electrical system designed suitably for the power consumption ? are there any IP - protection sealing requirements needed ? . if the application involves a flow measuring system ; the isolation -- valves should be commissioned by equalising the pressures across the instrument manifold. then opening slowly theLP low pressure isolator, and then fully, and finally opening the HP isolator to commission the instrument .
Why be use the -48 volt for bts?
48 is volt scale and negative voltage is used for safety of media, to prevent attanuation and noise.
Why you are using negative voltage in the BTS?
1. To reduce the lighting effect mainly in rainy season. 2. Less corrosion because +ve can create more corrosion in the BTS system. 3. Safer for human body.

Why use -48V dc in bts?
-48 v is given to BTS because in this voltage Noise generation is minimum. Because two terminal comes out from the battery and through red color wire we ground the +ive terminal so that possibility of noise interference will get zero because noise occurs only in the +ive terminal that's why we use -ive voltage in the BTS.
