Frequently Asked Questions – Voltage Stabilisers
1. Do we have multiple-phase voltage stabilisers?
Just as we have single-phase and three-phase current supply, we have multiple-phase voltage stabilisers. However, you will need using these three-phase voltage stabilisers only if you have a three-phase motor or you require providing stabilizing voltage for the entire three-phase setup.
Usually, our electrical and electronic appliances work on the one-phase stabilisers. There is no need to connect your entire house to a voltage stabiliser. These stabilisers also consume electricity. If you use these devices for a single appliance like your AC or your TV, you can always switch it off when not required.
2. How much current do these voltage stabilisers consume?
Many people are unaware that voltage stabilisers also consume electricity. The energy consumption of the stabilisers depends on their efficiency. A stabiliser with an efficiency of 95% to 98% (as is the norm) will consume 2% to 5% of the load.
Resultantly, a 1000 VA stabiliser will consume up to 50 watts (peak load). Leaving the stabiliser switched on for 10 hours can result in consumption of 0.5 units of electricity.
3. Is it advisable to have individual stabilisers or a consolidated mainline stabiliser?
Not all your electrical devices need the support of a stabiliser. You should be protecting your expensive appliances such as refrigerators, washing machines, televisions, air-conditioners, and so on with voltage stabilisers.
It is better to use dedicated UPS for computers as the UPS mechanism is different from that of a stabiliser. As voltage stabilisers also consume electricity, you should not use mainline stabilisers. You can switch off the individual voltage stabilisers if you do not intend to use the appliance.
4. What is the concept of in-built voltage stabilisers in the modern refrigerators and TVs?
Most of the modern TVs, refrigerators, and AC units come with in-built voltage stabilisers. The usage of electronic circuits like the SMPS (Switch Mode Power Supply) makes voltage management easy. The present-day LED TVs can work even under low voltage.
The mechanism is such that they can work in the voltage range of 110V to 290V. Therefore, there is no need to have a dedicated voltage stabiliser for such devices. Even refrigerators, AC units, and washing machines come equipped with such in-built stabilisers.
5. Are there different stabilisers for different appliances?
Every appliance in the house has different features. They come with specific energy limits. Depending on the energy limit, you need voltage stabilisers. The manufacturers engineer these voltage stabilisers after considering the energy limits of these appliances.
Hence, you have different voltage stabilisers for TVs, washing machines, ACs, refrigerators, music systems, ovens, and so on. The following categories of voltage stabilisers are available in India.
Digital Stabiliser for LED/LCD TV and Music Systems, Stabilisers for CRT TV and Music Systems, Stabilisers for AC, Stabilisers for Washing machines, microwave ovens, and treadmill, Stabilisers for Refrigerators, Mainline Voltage Stabiliser
6. Why do LED/LCD TVs need voltage stabilisers when they have in-built voltage stabilisers?
Most of the LED and LCD TVs come with in-built stabilisers that can handle voltage fluctuations in the range 110V to 290V. The only use for the external voltage stabilisers for such machines is that the surge protection feature in the stabilisers protects these appliances from sudden current surges.
Electrical surges can occur when you suddenly switch on high-voltage appliances like electric motors and ACs. It can also occur during lightning strikes, short circuits, and at times during restoration of electricity supply after a long period of power outage.
7. Why do we use UPS for computers instead of voltage stabilisers?
The voltage stabiliser can stabilize the output voltage, but cannot store and power up an appliance. The computers need some time for you save the work and shut it down safely in case of a power cut.
The UPS allows you to do these activities by continuing the electricity supply to the computers even during a power outage.
8. What is the difference between an inverter and a voltage stabiliser?
An inverter is a device that converts DC into AC and helps your appliances function during power cuts. The inverters come with a battery that enables you to store electricity and use during a power outage. The voltage stabiliser does nothing of this sort.
The job of the voltage stabiliser is to stabilize the input current and ensure that the appliance receives electricity within the prescribed voltage range (230V). It does not work during a power outage.
9. What is a step-up and step-down stabiliser?
The principal responsibility of the stabiliser is to ensure that the output current is within the acceptable range of 220V to 240V. If the input voltage is less than 220V, the stabiliser increases the output voltage to a minimum of 220V.
Under such circumstances, you refer to it as a step-up voltage stabiliser. On the other hand, if the input voltage is higher than the standard range, the voltage stabiliser reduces the voltage to maintain the level within the permissible limits. Thus, it acts as a step-down stabiliser.
Now, you would not find it a challenge to buy the right voltage stabiliser for your expensive electrical and electronic appliances.
We have discussed the buying guide in detail and reviewed about a dozen voltage stabilizers for different appliances such as AC units, TVs, and refrigerators.
