Why do You Need a SCVS at your Home

You have invested heavily on gadget – gadgets that are essential part of your daily life. Fridge, Mixer, Induction heater, Microwave heater, Air conditioner and PC to name a few. Your entire day could be spoilt if any one fails.

You have chosen your residence’s location for your convenience – How do you handle the power situation there?

Studies have been made on power profile area wise and here are the some of the Voltage trends:

LOCALITY EXPECTED VOLTAGE PROFILE VULNERABLE EQUIPMENT and EFFECTS of VOLTAGES
In the heart of the city Unpredictable pattern of power usage by residents and traders leads to low voltage during daytime and evenings and very high voltage late nights and early mornings. Household electrical equipment struggle during low voltage and draw excess power during high voltage leading overheating or burnouts. Air Conditioners, Fridges, Water pumps, TV & Induction Heater, Phone chargers, Play stations, music systems, Home theatres, Computers and DVD players.
City outskirts Sudden increase in housing and construction without the EB permission leaving EB unprepared to handle the extra loads. To compensate for line drop they tend to boost the voltage in the transformers. This leads to a very wide variation of the voltage depending on the load conditions. Failure of electrical equipment is rampant in these areas. Air Conditioners, Fridges, Water pumps may fail. Lamps are either very dim or very bright. Fans runs slow in the evening and irritatingly fast during the early mornings.
Industrial areas Frequent switching of heavy loads leads to power transients such as spikes and surge voltages continuous Voltage fluctuations though not as high as in the city outskirts or rural areas. Lamps flicker irritatingly. Fans keep on changing speed. Stabilizers attached to the fridge and ACs, keep chattering.
Electronics intense loads such as computers, TVs, Microwave and induction ovens and small gadgets like modems and mobile chargers can get damaged by voltage spikes and surges.

You have the choice of Protecting the Equipment.

We at Technohertz are aware of this situation and have made a SCVS especially for your home.

A SCVS at the input of your house protects your equipment. The gadgets work optimally. You live with your peace of mind intact.

But what about my stabilizer I have for AC, fridgr and computer UPS.

A relay Voltage stabilizer has no place in your home.

Read the comparison between the relay stabilizer and a SCVS and decide:

Point No Relay based stabilizer Servo Controlled Voltage Stabilizer
1 Voltage corrected in steps. Seamless and fine correction of output voltage.
2 Stabilizer Supplier decides the output voltage and tolerance band. Minimum tolerance is 10%. e.g., When out is set at 230 V the voltage available at output could be between 207 and 253 V for a good stabilizer. You can set the output voltage anywhere between 210V and 240V and maintain the variation within 5 Volts if you set the output to 1% regulation. You have the choice of setting it to 5% tolerance depending on your need. Can correct a very wide variation of Voltage.
3 The output of the stabilizer is not cut off in case of abnormal output voltage. Programmable output cut off cuts supply to the load if the voltage is dangerous to your equipment.
4 Consumes high power at high voltage input. This adds to an increased electricity bill. Almost a uniform consumption of power over its entire working range. A small Power consumed by stabilizer is compensated by the savings it can give you.
5 Not fit for a group load or the entire residence. The variation of the output voltage during relay change is very large and the flicker in light and fan speed variation is very irritating to the consumer. The output is always close to the set point and the correction is seamless. The correction is hardly ever felt even if the output is set for a 5% variation.
6 You will need a stabilizer for each and every critical load. Can be connected to the entire house and the benefit of the stabilized voltage is available to all loads. Uniform light and same speed throughout the day.
7 Stabilizer is placed all around the house – one for each equipment. One stabilizer for the entire house. It can be placed close to your EB meter out of sight.
8 The output from these stabilizers are never monitored or corrected. A relay selects a tap at the input of the stabilizer assuming the correct output is available. A welded relay (common occurrence which goes unnoticed) can cause the load to draw large current. A welded relay can also abnormally increase your electricity bill. The correcting system always monitors the output voltage (voltage to your equipment gets). If the voltage is not correct the output is cutoff. This added feature works independent of the voltage stabilizer section.
9 Cannot be fitted with a surge suppressor or a line filter. Line filter and a surge suppressor remove these glitches to protect the sensitive loads.
10 No provision to measure the output voltage is available in most of the models. Comprehensive metering is provided. You can also monitor a particular load and assess its performance. A malfunctioning AC or fridge can be identified.
11 No savings on EB bill With output voltage set properly you can expect a 10 to 15% in savings your EB (energy) bill.
12 No protection from overload Electronic overload protection will cut off output in case of overload or short circuit. Prevents major catastrophe.

You would have invested in a UPS for your PC. UPS acts as a backup power supply. When power fails the internal battery support the computer. When mains supply is available raw EB power goes to your PC exposing it to spikes and RF noise. With a SCVS, stabilized and filtered voltage is supplied to your computer. Since the UPS is getting a stable voltage the battery charges better and need to switch to battery mode at low input voltage is minimized.

Know About The Power Line Disturbances

stabilizerTransient riding an AC waveform can reach a very high Voltage as in fig. 1 of even a few thousand volts. Since the energy content in these transients can be low it may not damage a big load like an AC or incandescent lamp, but it can damage the electronics in a sensitive load by puncturing a device. Spike is like a red hot pin which can burn a hole through a fabric, whereas a warm brick has several times more energy than a red hot pin but will not damage anything.

The frequency component of a spike will be in 100s of kilo Hertzs as against 50/60 Hz mains.

Transients can also be in regularity in an industrial environment. Power lines can also act like an antenna and pick up radio frequency signals. The exaggerated version of the waveform is shown in Fig.2. These RF signals can go into the electronics directly and may cause data disruption, though they do not cause physical damage to the system. Technohertz SCVS for domestic use are fitted with a line filter to filter out RF noise over and above the transient suppressors to kill spikes and surges.
