[#1] 電錶房去屋企電箱電線問題請教    
屋企低電壓得208-214V之間,由住宅樓層三相電錶房入去我屋企電箱果條電線,需要用幾多MM粗的,因為大廈管理幫我更換外面條電線,唔該!

Very dangerous. Must ask a cFu with licence to do it.
The cFu can check the whole system. Low voltage may not be only due to the wiring.

我問了中電,我家住宅單位的電壓經常維持在208-214V之上限,不足220V,可否能提升電壓呢?

他們回覆是我座大厦火牛房已足220V,無計喇!

公家地方我無權力去搞,已經要求管理公司派技工更換條新線16MM(座樓25年)及CHECK電錶房可否能提升電壓

多謝你們的回覆

我住高層,每層有三相電錶房,再分支單位供電,火牛房在地下,降電壓的其中原因之一,昨日去管理處要求跟進事件,晚上即刻有番213-215v,如同一時間多人用電,一下即降208v-210v,好過平時朝晚都在208-211v之間徘徊

我理解換線同提升電壓無乜直接關係,舊樓成25年多,外面D線好殘舊夠期更換,現在等待管理公司派技工換條粗D新線,希望會有幫助及改善電源的質素

多謝你們的回覆

我住的大廈,須然舊,但用錶量度都有AC 224V,幾年前大廈業主立案法團,為大廈上昇總線更新,舊上昇總線是鋁線,新換上昇總線改為銅線,每戶錶後到單位舊總線由30A更新到60A。

我一人的需求,大廈業主立案法團未必會做總線更新,我唸有D難度
屋企電箱寫有100A,電壓最高得215V,最低208V
現在晚上10時有214V,之前重未試過,日日呢個時間最多得210V-211V
拔電源線再插牆蘇開機的一下,盞燈就閃一下,唉....

Bumboobee hing,

The electricity condition of your house is quite 'Big Wok'!
Purepower is not cheap but helpful for your situation. Go to Excel & have a look.

CKKeung hing,

I used Power processor for my CD Player and Pre Amp.
I think any Power processor does not suitable for Power Amp.
Not enought voltage for Power Amp is the main problem, thanks for your advise.

Bumboobee hing,

Most of the power-conditioners are not for power-amps but the top models of PurePower (2000 & 3000) are exceptions.

Arrange a demo at Excel & you will be surprised.

Bumboobee hing,

Excel carries Krell poweramps that are as power-hungry as your Pass Labs X350.5.
Why not call them to arrange a demo? You have no loss.

BTW, my friend's MC2 Audio MC1250 (750W x2) shows no compression when connected to a PurePower 2000.

CKKeung hing,

Sorry! Late for reply!

Firstly, I will be waiting for replace home ouside cable.

Next step, I will call excel to arrange a demo to test for my 220V power Amp.

I never to use Pure Power Products. If not suitable, Can I return to excel without any problem?

PS: My Best Choice of Pure Power 2000/3000 and New PS Audio D5/D10

Which one is the best?

Many thanks for me a good advise and I have a good choice to replace my old AC regenerator.

Bumboobee hing,

My personal preference of power-conditioner is PurePower 2000/3000 which are more musical than PS Audio Powerplants.

Excel may not be willing to lend you a PurePower for home trial but you can ask them to set up a demo at their showroom : Krell poweramp plugged & unplugged into a PurePower.

I think power amp are always better plugged direct to wall socket. I am using Burmester power supply and Gryphon Antileon. I found that even with Burmester power supply the sound seems more vibrant and powerful when plugged to wall socket direct. I only plug my CDP and Preamp to the power supply.
