Introduction | BIS for AC Static Prepayment Meters
The Indian power distribution sector is undergoing a sea change in terms of minimizing losses in the power transmission process and optimizing the billing process with the help of customer-friendly electricity usage methods. Among the most successful methods used in the power sector is the Alternating Current (AC) Direct Connected Static Prepayment Metering system.
In order to have uniformity, safety, and accuracy in such meters, the Government of India has made it mandatory to have Bureau of Indian Standards (BIS) under IS 15884:2010. It is ensured through such standards that the AC static prepayment meters regarding active energy class 1 & 2 accuracy have strict standards.For the manufacturers, importers, as well as the suppliers, the process of BIS certification is not a matter of mandatory compliance, rather it leads to government contracts, DISCOM approval, as well as market approval throughout the country.
What is BIS Certification for AC Static Prepayment Meters (IS 15884:2010)?
BIS Certification is the confirmation of compliance with the applicable Indian Standard, which is given by the Bureau of Indian Standards.
IS 15884:2010 particularly applies to
- Alternating Current
- Direct Connected
- Static pre-payment meters
- Used for measuring active electric energy
- Accuracy Classes Accuracy Class 1 and Accuracy Class 2
These meters require no current transformers and are mounted directly to the supply line and are usually seen in domestic and business or utility-managed environments.
Key Features of AC Direct Connected Static Prepayment Meters
- Prepayment-Based Energy Consumption
- Consumers are also required to recharge before they consume power. This ensures that there are no disputes arising from bills or unpaid fees.
- High Accuracy Measurement Class 1 & 2 meters are capable of measuring active energy accurately regardless of voltage or load changes.
- Static (Electronic) Technology There are no moving parts. This leads to increased product life and reliability regarded against electromechanical meters.
- Counter Tampering Magnetic interference neutral disturbance, reverse current, and unauthorized access are all detected by inbuilt functions.
- Direct Line Connectivity Specifically designed for light to medium load operations without the aid of transformers.
Why BIS Certification is Required – Key Reasons
1. Lawful and Compliance in India Prepayment meters for the utilities sector or used in regulated environments must compulsorily be certified by BIS as part of the Compulsory Registration/Certification Scheme.
2. Protection against Sub-Standard Products Thus, it is assured that only verified meters are supplied to the Indian power sector with the certification from the BIS.
3. Mandatory for Government & DISCOM Projects Electricity distribution companies and public sector undertakings allow only BIS-approved meters to be installed.
4. Uniform National Quality Benchmark IS 15884:2010 provides uniformity in all makers, ensuring compatibility and reliability among states.
5. Market Access & Brand Credibility The use of the BIS mark increases the credibility of the manufacturer, thus enabling a high degree of acceptance within the market.

Documents Required for BIS Certification
| Category | Documents Required |
| Business Documents | Business license/registration, ISO certificate, organizational details |
| Manufacturer Details | Factory layout, process flow chart, machinery list, production details |
| Product Documents | Product specifications, component list, user manual, model details |
| Testing Documents | Test report from BIS-recognized lab, sample details, test request form |

Challenges of BIS Certification Without a Consultant
Obtaining the BIS certification independently is complex and time-consuming. General challenges include:
1. Complicated Technical Documentation Technical expertise is needed for understanding standard clauses, test parameters, and report formats.
2. Delays in Lab Coordination Testing can be repeated and seriously delayed if the samples are wrong or if the documentation is incomplete.
3. Non-Conformities at the Factory Even minor gaps in quality control or testing infrastructure can bring about inspection failures.
4. Explanation of IS 15884:2010 Misunderstanding accuracy classes, test conditions, or marking may serve grounds for rejection of an application.
5. Increased Cost & Time Overruns Re-testing, re-inspection, and follow-ups raise timelines and costs of certification considerably.
