Introduction
Automatic Voltage Correctors (AVCs) are significant electrical devices that serve the purpose of maintaining voltage stability in household electric supply systems. In India, Automatic Voltage Correctors have to comply with the standards set by the Bureau of Indian Standards in IS 8448:1989.BIS standards for Automatic Voltage Correctors ensure that they meet certain requirements in terms of quality, safety, and performance. This standard is specifically applicable to step-type automatic line voltage correctors for household appliances, which safeguards them from damage due to voltage fluctuation.
What is IS 8448:1989?
IS 8448:1989 is a standard set by the Bureau of Indian Standards that specifies the technical characteristics of step type automatic line voltage correctors used in domestic applications. The standard offers in-depth guidelines regarding the design, construction, and performance of these devices in order to ensure their smooth operation in the regulation of voltages.It states the ways in which the voltage correctors should be able to function in different input voltages and still be able to deliver output voltages that are safe and suitable for domestic use.
Key Points:
- Scope of the Standard:It applies to step type automatic voltage correctors used for voltage regulation for household electrical appliances.
- Performance Requirements:It specifies requirements for maintaining a stable output voltage level in spite of changes in the input supply voltage.
- Safety Guidelines:It includes requirements for safety from electrical hazards such as short circuits, overload, and overheating.
- Design & Construction:It includes requirements for the quality of materials, components, and construction of the product.
- Testing & Compliance:It includes requirements for various tests to be performed on the product for BIS certification, such as voltage regulation, insulation resistance, and durability tests.
Products Covered Under IS 8448 : 1989
The standard IS 8448:1989 was developed by the Bureau of Indian Standards and applies to step-type automatic line voltage correctors for domestic purposes. The devices are intended for regulating the varying input voltage and delivering a constant output to guarantee the safe functioning of domestic electrical devices.The standard encompasses various voltage stabilizers and correctors that utilize a single-phase power supply system. The standard is focused on step-type devices that employ step correction mechanisms, usually in the form of relay-based systems.
Key Reasons:
