Thanks Che Kuan Yau. You answered my question [smile]

Need some help on the above subject. Any reference materials please Thanks

Hi Daren my location is Brunei

I would like to know a valve manufacturer that can supply forge gate valve AP1602 with MESC specifications. The size of valve is 50mm diamter and needed on site by Nov2023 Quantity of valve 10 sets. I can email complete details of the specifications Thanks for your help in advance.

Does anyone has had any experience in using airbag cables manufactured by Prysmian cables?It claims that it has better mechanical protection easy to handle compare to lead sheath cable and has high impact resistance.Has this cable been widely used internationally or has KEMA CESI or type test...

My experience is in the medium voltage distribution systems and interested in learning PLC and SCADA.Can anyone please help recommend a beginners book to me. Thanks a lot guys

Thanks a lot guys.These are all very helpful.One last thing is that, Do I need to do a seperate test for the power transformer before installing the reactors? According to the records from my client they have done the Zero Sequence impedance test for the power transformer previously

What are the necessary testing and commissioning required for a new installation of current limiting reactor in series with the power transformer.We are shutting down one of the transformer and restore power after installation of reactors.

Can someone tell me the importance of KEMA or other international independent type test certificates for cables if the cable manufacturer is also doing their cable factory test.

Kiribanda If it is the sound wiring that the utility would like to ensure between any phase conductor and neutral conductor, my question is how they arrived at a maximum loop impedance requirement of 0.4 ohms for overhead and 0.2 ohms for underground.

Hi Kiribanda I would think that it would be the earth fault loop impedance otherwise is there any other type of loop impedance test other than the above.

We are doing replacement of 4 wire,415V rated overhead distribution pole. We are required to do the loop impedance test before energizing the line and was told by the utility that acceptable reading of 0.4 ohms (L-N)and report should it exceed this reading. Can anyone tell me why is the maximum...

Anyone knows the life span of a power cables supplying submains if not loading it to not more than 80% of its full current rating.

Go to format, bar styles and omit the external task

Swithboard is a term I use for low voltage applications Switchgear is the term I use for Medium to High Voltage.
