Components used to make the Over Voltage Protective Device:

01. Single Phase Energy Meter

Single Phase Energy Meter
Fig 02: Single Phase Energy Meter

The measuring device with the help of which the electric power or energy of a circuit is measured is called Energy Meter (Energy Meter). Also called a watt-hour or kilowatt-hour meter. home appliances, we used a single-phase energy meter. The single-phase energy meter is directly connected between the line and the load. Both coils produce their magnetic fields, when the meter is connected to the supply line, and the load. Energy meters are used in homes and in industrial applications where we want to found that how much energy is being consumed by home appliances and electrical equipment.

02. VPD

Fig 03: VPD

A voltage protector device, also called a lightning arrester, is an electronic device that provides voltage to various electronic devices, appliances and communication lines. When an external interference causes a sudden current or voltage to be generated in an electrical circuit or communication line, the voltage protector can be used for a very short period of time. Within the shunt operating voltage protection device VPD name is also increased Argestor, all amplifier protectors intended for specific purposes are actually a type of quick switch and the sequence protector is activated within a certain voltage range. After activation, the suppression element of the sequence protector will be disconnected from the high-impedance state and the L pole will transition to a low-impedance state.

03. RCBO

Fig 04: RCBO

RCBO Stands For Residual Current Circuit Breaker With Over-Current. These devices are designed to ensure the safe operation of electrical circuits breaker, triggering disconnection whenever an imbalance is detected. The other type of electrical fault is the overcurrent flow, which may take the form of an overload or short circuit. The residual current circuit breaker (RCBO) insulation should also operate within the corresponding specifications. This thereby provides protection for people, equipment, and property.

04. Electric kettle

Electric Kettle

Water can be heated easily and quickly by using an electric kettle. The water capacity of an electric kettle starts from one to 10 liters. Take care that water does not stick to the kettle when it is connected to electricity.Terms of Use and Procedures. You can use a dry cloth to take extra care of the handle of the kettle. Use a separate electrical connection for electric kettles. Disconnect the electric kettle by turning off the switch. Electric kettles cannot be used for heating any liquid other than water.

Frequently Asked Questions

What is the over-voltage and under-voltage protection of batteries?

Under-voltage switch (22) can block only discharge power supply current, any recharge current may pass through it regardless of its switch Circuit diagram state. Over-voltage switch (28) can block only recharge power supply current when switched off and will always allow discharge Project system current to flow regardless of its switch power supply state.

How do you protect under voltage?

Basically, under-voltage protection is nothing but a circuit diagram board that is placed between the mains and the power supply batteries, which is capable of detecting any under-voltage Circuit diagram condition. This protection device can easily check the phase-to-phase Circuit diagram voltage of the power supply device.

What are the advantages of over and under-voltage protection?

So it is important to use overvoltage and undervoltage Circuit diagram protection for electrical and electronic power supply appliances. This circuit diagram incorporates a low-voltage and high-voltage tripping mechanism to protect the Project system appliances from any damage due to voltage power supply fluctuation.

What is the difference between overvoltage and overcurrent protection?

Overvoltage and overcurrent and protection work well for protecting a device that has a single maximum voltage and current — some devices' maximum current changes with the voltage. An example is a DC-to-DC converter, as its input can accept a power supply range of voltages, and it provides a regulated voltage Project supply output.

What are the protective devices used for over voltage and over current protection?

Overcurrent and protection devices such as fuses, breakers, and others limit the Circuit diagram current to the proper rate and disconnect the short circuits diagram. The type of overcurrent protection Project system used and the maximum current passing through the circuit diagram components determine the size of the power supply overcurrent protection project system.
