How Surge Protectors Work-As we know a good surge protector is a safety device that safeguards electrical appliances from electrical overcharges and damage. The surge protector is equipped with non-ohmic current-voltage characteristics, commonly known as metal-oxide varistor( MOV) that redirects the extra voltage( above 120 V) to the ground wire. The high-electrical resistance transient placed inside the surge suppressors ensures a consistent power supply to any connected electrical device. An electrical surge or a short-duration intense voltage( surge and spikes) is caused due to electrical grid malfunctioning, constant on/ off of large appliances, wiring faults, lightening impulse, burning out of capacitors or semi-conductors, etc. In other words, if the electrical surge or spike lasts for more than three nanoseconds and the additional voltage exceeds 120 V, it damages the electronics. Therefore, the purpose of a surge diverter is to direct the unwanted surge current to a level that will not start a fire and damage the electrical appliances.As stated in this article, you can browse your selection of available deals on smartphones and top brands and explore the cell phone service plans that best suit your needs.
Voltage Stabilizer- This electrical device is dedicated to providing electrical protection securing the galvanic operation and maintenance work on the circuit grid. It is also known as a “V- guard” that is manufactured to safeguard all types of electrical appliances from permanently damaged conditions and trouble-free operations. The direct current or DC is measured in Kilowatts( kW) and kilo-amperes ( kVA) but an alternating current (AC) is measured in phase amperes. The most important thing is to know that in India, the standard single-phase electrical distribution system is 230 VAC, 50 Hz. The voltage stabilizer used in electronic circuitry controls the low-level voltage fluctuations( 80- 100 VAC) to high-voltage fluctuations ( exceeding 22o VAC). Therefore, in simple terms, we can say that Voltage Stabilizers are optimally engineered for overload protection features from frequent high or under-voltage conditions.
How Voltage Stabilizers Work- Fluctuations can be sudden high-voltage or low-voltage supply to the electrical appliances. The need for a voltage stabilizer is to ensure a constant power supply to all the electrical appliances at all times. The over and under-voltage conditions are unfit for the functioning of electrical appliances causing computational errors. The voltage stabilizer protects from harmful galvanic consequences and corrects the buck mode operations. To function effectively, and provide a constant voltage output, the voltage regulators deduct the secondary output voltage from the incoming variations. Not only they are the ideal solutions for extending the lifespan of your equipment but save 40% on energy usage. This electrical device works on the principle of a transformer that sends a constant voltage to the load and when there is a low voltage, the stabilizer increases the voltage output through buck operation. The circuit- board, in-built transformer, and high-power electromagnetic relays are the three main components of a stabilizer. Moreover, there are three types of voltage regulators namely: Relay, Servo, and static stabilizers to control the power-electronic control circuit.
Both electrical appliances protect against electrical fluctuations to enjoy a trouble-free and comfortable life, however, they are different. Therefore, the below segment will brief you about the major variation between surge protector vs stabilizer.
Surge Protector |
Stabiliser |
| The surge protector works on the dispersion principle thereby, protecting your computer and other electrical appliances. |
The regulator works on an electromechanical transformer concept that adjusts the power input variances up to +/- 20%. |
|
They are an indispensable initial line of defense tools that divert the extra voltage away from the electronic device. |
It stabilizes the power supply load to bring the voltage to a normal level. |
|
Limitations- Surge Protectors are inexpensive galvanic devices that are used for sudden voltage spikes. |
Stabilizers are used for frequent voltage fluctuations( high and low). |
|
They are also called power strips that protect the power outraged fluctuations (sudden increase) due to lightning strikes, etc. in the power grid. |
They are comparatively expensive and complex structures that require a professional installation process. |
| They contain Metal Oxide Varistors( MOVs) that control the instantaneous high current and voltage. |
They are used in the areas of unreliable fluctuating power supplies to regulate the incoming voltage level for the connected device. |
