BIS Certification for AC Static Transformer Operated Watt-Hour and VAR-Hour Meters, Class 0.2S &0.5S IS 14697

Ac Static Transformer Operated Watt-hour And Var-hour Meters,  Class 0.2s & 0.5s

Product Description

AC Static Transformer Operated Watt-Hour and VAR-Hour Meters, Class 0.2S & 0.5S, are high-precision instruments used for measuring both active and reactive energy in power systems. These meters are designed for industrial and commercial applications where accurate and reliable monitoring of energy usage and power factor is essential. They are typically used in conjunction with transformers to measure electrical energy and reactive power with high accuracy. Class 0.2S meters offer an accuracy tolerance of ±0.2%, while Class 0.5S meters allow for a tolerance of ±0.5%. BIS certification ensures that these meters conform to the stringent standards set under IS 14697 for performance, accuracy, and safety.


Introduction

The Ministry of Commerce and Industry, through the Department of Promotion of Industry and Internal Trade (DPIIT), has mandated BIS certification for AC Static Transformer Operated Watt-Hour and VAR-Hour Meters, Class 0.2S & 0.5S, as per Indian Standard IS 14697. This regulation, effective from January 1, 2024, ensures that the meters meet critical accuracy and reliability standards before they can be marketed in India. The ISI mark, issued by BIS after certification, indicates that the meters comply with national standards, ensuring consumers and industries have access to reliable energy measurement equipment.

Why is BIS Certification Necessary for AC Static Transformer Operated Watt-Hour and VAR-Hour Meters?

BIS certification is vital for AC Static Transformer Operated Meters as it ensures the accuracy and reliability of energy and reactive power measurements. Accurate energy meters are essential for correct billing and for the efficient operation of electrical systems. Inaccurate readings can lead to under-billing or over-billing, making certified meters crucial for transparency in energy consumption. Compliance with IS 14697 ensures that the meters will function reliably in real-world applications, providing industries with trusted and accurate data for energy management.

Overview of Indian Standard IS 14697

Indian Standard IS 14697 defines the technical requirements for AC Static Transformer Operated Watt-Hour and VAR-Hour Meters, specifying performance and accuracy standards essential for reliable energy measurement. The standard mandates that Class 0.2S meters exhibit a maximum permissible error of ±0.2%, while Class 0.5S meters must stay within ±0.5%, ensuring high accuracy. These meters are capable of measuring both active power (watt-hour) and reactive power (VAR-hour) with precision, making them crucial for comprehensive energy management. The standard also emphasizes temperature resistance and stability, ensuring the meters maintain accuracy across a broad range of environmental conditions and operating temperatures. Additionally, reliability is a key requirement, ensuring that the meters perform consistently and durably over extended periods, even in challenging industrial, commercial, and utility environments. By adhering to these specifications, IS 14697 guarantees that the meters provide accurate, stable, and reliable readings, which are vital for the efficient management of electrical systems and energy usage.

Process for BIS Certification

The process for obtaining BIS certification for AC Static Transformer Operated Watt-Hour and VAR-Hour Meters under IS 14697 follows several steps to ensure compliance with the required standards:

  1. Application Submission: Manufacturers submit a formal application to BIS, including all necessary documentation, such as technical details of the meters and manufacturing process.
  2. Document Review: BIS reviews the submitted documents to ensure that all technical requirements are met and the documentation is complete.
