I can tell you that they will sell it around S$500 to S$1K, price up even after PSB approval. But IT IS NOTHING EXCEPT A BUNCH OF VERY CHEAP CAPACITORS. The way it had been sold and bragged is identical with Lehman Brother's bonds very very misleading and serious misinformation.

It is a basically just a poorly concepted and improperly installed Power Factor Correction capacitor, nothing more than that. The capacitors inside could worth less than S$20 indeed.

It is wrong in concept and improper to be designed this way.

Because induction loads e.g. motors should have their own power factor correction capacitors installed nearest to their own motors, for reason #1, and for #2, they are supposed to be ON/OFF or connected/disconnected together with their motors. #3, they are actually even supposed to be changing according to motors' speed.

It is Wrong and non-effective to have one such capacitor device to be install Blindly Centralized to a house or office or factory. It may have the OPPOSITE EFFECT against intended goal of saving currents if done in that way.

While motors without power factor corrections can cause undue increased currents in circuits (& hence extra resistance lost via heat) Over corrections gets the same results.

Blindly connecting a bunch of capacitors without knowing the situation of power factor and the operations of motors usually results in over correction and cause extra current as well when circuit becomes overly Capacitive instead of Inductive.

The demo device designed and shown are misleading and bluff. Their product info lacks lots of truth that they did not disclose. The amount of savings claimed is very very subjective, and must very case to case because Not Every Household runs the same number (& power) of un-corrected motors. Besides motor, the traditional florescent ballast is another main factor.

For more info please search on Power Factor Corrections for (usually motors) induction loads on Internet.

I had seen many such Con products from every 3rd world country, Singapore is the only 1st world that con people this way. The PAP's so called Singapore Branded CON!

You should reproduce your article in Mandarin. Seems like the targeted audience for this product is for the elderly and the mandarin speaking population.

As far as I know there is no penalty for low power factor for domestic consumers drawing Low Voltage 230/415V supply. Only slight advantage is you draw less inductive current, and hence better use of the electricity you paid for, when you install the Capacitors across the inductive load terminals. It is no rocket science.
The penalty applies only to High Tension comsumers drwaing e.g. 22kV supply.

PSB 竟然认证这些欺骗性的商品？



这些所谓省电器的商品是多数以不正确概念设计，然后以欺骗性和隐瞒性的推介手法来销售的。主要来自第三世界国家，想不到新加坡这样的所谓发达国家，居然还有PSB认证的这些所谓省电器！

让我来讲穿这些所谓的省电器，里面其实就是几个非常便宜的“电容器而已。价值可能不超过S$20。这些所谓的省电器却通常卖数百元，而PSB认证的可能卖上1千元以上。

电容器像这样子：

其实这样的电容器只不过是纠正所谓的电功率因数，而已，详细的资料在网络上很多。

电功率因数通常是针对电感性的电力负载（例如马达和传统日光灯线圈）利用相应的电容器（必须精细计算）来进行匹配纠正。以相应的电容性来抵消负载的电感性，这样就最简单的纠正了所谓的电功率因数了。这样匹配的结果使电力线路里不必要的强电流减低，减少了这些额外电流所造成的电阻力热损耗（即电线发热耗能）。

正确的电功率因数补偿电容，第一：必须经过进行精确的测量计算匹配。第二：必须正确安装在负载的最短线路上（直接在马达上，直接在日光灯里面）。第三：必须直接紧密跟随电感性负载的开关和调节变速（随马达的操作开和关，随日光灯开和关）。

这样才是正确和有效的。不能够随便盲目的乱用几个电容器，连接在住家；办公室；工厂里面的电路上，根本不经过测量计算，不随负载配搭，这样枉然自称省电器其实是无效而且反而可能造成过度补偿，使整个线路偏向电感性，而造成电功率因数更糟糕，更浪费电力。

简单的说，要利用补偿电容纠正电功率因数，必须在马达和日光灯等电器里面经过测量计算知道电功率因数偏差值之后进行准确补偿。而补偿的电容器至少必须跟随马达或日光灯直接开关。不是一直不断的连接在线路上。

必须连接在马达和日光灯的最近线路上，不是在家里的总开关附近。否则，额外的电流依然经过很长的电线来发热损耗电力。没有效果了！必须把电功率因数不良所造成的额外的电流控制在最短的线路内才有省点节能；节热耗损；保护电器的意义。随便在电表附近固定的安装所谓的省电器是太天真妄想的做法，如果有效只是侥幸的。这些所谓的省电器根本不知道如何配合电器的电感性来调节只是盲目的固定连接电容器。哪里可能有效？

我所指出来的就是这些所谓省电器的推销人根本不解释的电学知识，他们可能都 不懂。新加坡PSB卻是毫无理由不懂的。是什么动机让PSB配合这些欺骗性的商品，商业调查局应当调查。

售卖这样的所谓省电器，和雷曼兄弟的财经骗局差别不大。PSB认证的责任和金融管理局的监督责任也是相当的。

官府可以配合骗子来害百姓吗？

Exactly.

Even in a motor e.g. electric fan that has some speed control aka number 1, 2, 3, 4, 5, for user to set speeds. The required power factor compensating value of the capacitors are not the same at each speed. You can not expect to blindly correct the power factor by simply connect a fixed capacitor permanently on the electric fan. Different capacitor values are needed at different speed in order to have the desired effects.

That is why these so called power saver devices are purely exploiting consumers. Just like the Lehman Brothers' bonds!

Thanks for the translation!

Now I will print it tomorrow and show it to my senior friends.
