Home power compensator (HPC)

Why HPC compensator is better than other ones, commercially available?

 Answers to questions What is reactive power? 

 

Бытовой Компенсатор реактивной мощности БКМ

 The functional principle is based on the effect of reactive power compensation, which occurs during work of electrical motor and other consumers with inductance. During its work, the device converts reactive energy in active.

Home power compensator monitors the presence of reactive power in the grid, and if it is present, HPS connects built-in compensating device to the grid. If electrical devices, which do not generate reactive power (e.g., iron), are plugged to the grid, because the compensation is impossible and there is no need in connection of compensating device.

 The efficiency of reactive power compensation depends mostly on the balancing of the compensating device with the consumer. That is why our home compensators are divided into several models as per power (See the table below).

Why HPC compensator is better than other ones, commercially available, and how they deceive us

 

• Unlike other devices, HPS compensator can monitor the reactive energy and connect the built-in compensating device only when necessary. The devices offered on the market cannot do this and at the absence of relevant consumers, turn themselves into consumers that work up your counter. Usually such devices are connected only to a power outlet, and not directly to the consumer.

 It is easy to check the way the compensator HPS monitors reactive power for example, by turning on the iron, and then refrigerator. At turning the refrigerator on, the indicator “Compensation” will turn on, when iron or fireplace are being turned on, the indicator "compensation" does not glow, because there is no need for compensation. 

Some manufacturers claim that their little device works effectively with the capacity from zero up to tens of Kilowatts!

 It is impossible for several reasons:

 a) For the compensation device to have maximum efficiency it is adjusted for a narrow range of powers, that is what we have done by designing several models of compensation with different power;

 b) The device, compensating reactive power in a dozen kilowatt, cannot be the size of several packs of cigarettes, because there will not be place enough for all elements providing the compensation of such powers. For power compensation of 10 kW with the use of modern technologies, the minimum size of the box should be 30х20х15 sm, so that all compensating elements could be placed there. 

Some manufacturers claim that their device, activated by connection to outlet is smart...???

 We can say with certainty that it is not possible because for any smart action by the device, it is necessary to have data on the phase shift between current and voltage. The irony is that device can receive data on the voltage from the outlet, but it will not be able to receive the data on current due to the inability to measure the current through the outlet. (For those who do not know - current is measured in circuit break, i.e. wires). 

It is claimed, that device with the size of cigarette packs stabilizes voltage.

 Just look at the available voltage stabilizers... and made conclusions. 

There are statements that there are the devices, allowing to save energy during the use of all electricity consumers.

 Such devices do exist, but they have a big disadvantage - together with the economy, the consumer receives less energy than standard work from the grid. Accordingly iron or heater will heat worse... So there is no sense in this economy.

 Also, despite demonstration of functional capability of such devices, people normally do not pay attention to the important factor — the measurement procedure. The method of connection and availability of function RMS of the device (expensive devices) are very significant. Cheap devices use simple methods for measuring of current and voltage variables and even a significant change in the forms of grid current (for example, cut sine wave, which is obtained after passing of current through the thyristor) may not affect the measurement result. And in the end we have not accurate results. For correct measurement, it is necessary to use the instruments with RMS support and take into consideration the power (power = voltage *current*cos(φ)) at the input and output of the devices. 

• Do you want your engineering teacher’s think you are dumb? Then tell him what manufacturers of these devices write: “the device when it is plugged to the grid has the least resistance in the electrical system. Therefore, all the energy is accepted by device on the load side". How should we understand this? The device takes all the energy? 

Answers to questions

Is the installation of this device legal?

 This is perfectly legal, the device is not cheating the electric meter. Home reactive power compensator does not make any changes in the electrical grid and you can plug any electrical appliances in the power outlet. Therefore, no approvals from net are required. 

What will happen if I plug the consumer with the power higher than capacity of the compensator?

 Nothing will happen to consumer, it will work, but the effect of economy will be less than the stated one. 

I heard that by adjusting the electrical system in resonance, one can achieve very efficient energy saving — in dozens of times. Do you plan to produce this kind of device?

 We already do... Our compensator can be joint can be considered as capacity, and the consumer — inductance. And as you know from physics lessons, together they form an oscillating circuit. If this circuit is properly configured, we can get into resonance with the grid. In this mode the energy consumption will be minimum and cos φ = 1. However, electricity consumption will depend on tuned circuit Q-factor, and tuned circuit Q- factor depends mainly from the motor characteristics (or another consumer), the load on the motor shaft etc. That is why we produce reactive power compensators with the narrow range of powers (see table 1).

 Rumours and stories on the Internet about the economy are exaggerated in "dozens of times". Bad tuned circuit Q-factor, which consists of electrical devices, not allows to achieve it.

• How to make sure that it works?

a) With the help of electricity meter

b) By using the split-electromagnet instrument or standard tester. Measure the current consumption before and after the compensator;

 c) Remember, that when saving is possible, then indicator “Compensation” is on during work of the consumer on the indicator.

 • Is it possible to plug several consumers to HPS?

Yes, you can. In this case, power consumption should be in the power range of HPS to obtain the maximum energy saving (see table 1).

 • Can one use HPS device on the entire apartment?

Yes, you can. You should take into account power of HPS is based on "reactive" consumers (air conditioning, refrigerator, daylight lamps, etc). Therefore, at the choice of HPS, other users are not taken in account.

For example: the apartment has a fridge (consumption 300 W), the heater (1500 W). For this apartment it is recommended to choose БКМ-03 (designed for a capacity of 150 to 500W) as the heater is not taken into account.

What is reactive power?

 Reactive power is the value that characterizes the workload generated in electrical devices by energy fluctuations of the electromagnetic field in the chain of the sinusoidal alternating current, and it is equal to the product of the operating values of voltage U and current I, multiplied by the phase shift angle φ between them: Q = U * I * sin φ (if the current is lagging behind voltage, phase shift is considered to be positive, if the current is leading - negative).

 

Or in other words: The Consumers of electricity, in which magnetic field is generated (motors, throttles, transformers, induction heaters, welding generators), cause lagging of the current from voltage (phase shift) due to the presence of inductance. Lagging of the current makes current to stay unchanged through the inductive load for some time after the tension became negative. During this time, the current and voltage lead to the formation of negative energy, which is returned back into the grid. During restoring of an identical sign of current and voltage, the same amount of energy is used for creation of a magnetic field in an inductive load. These fluctuations of electromagnetic field in alternate current circuits are called reactive power.

This video shows that current consumption (and therefore power) after the device is more than before. It means that less power is consumed from the grid.
