Notification
Power Capacitors of Self-Healing Type for A.C. Power Systems (up to 650 V) were brought under compulsory BIS certification through the Electrical Capacitors (Quality Control) Order, 2017, notified via S.O. 2434(E) dated 1st August 2017.Â
Enforcement Timeline
- The order came into force on 1st February 2018.
Overview
These capacitors are widely used in low-voltage A.C. power systems for power factor correction, improving energy efficiency, and reducing transmission losses. Being of the self-healing type, they automatically restore dielectric strength after minor internal breakdowns, ensuring longer operational life and system reliability.
Objective & Scope
The objective is to eliminate unsafe and substandard capacitors from the market, protect consumers against fire/electrical hazards, and ensure durability and reliable motor performance.
Products Covered
The standard applies to self-healing type power capacitors with a rated voltage up to 650 V, used in industrial plants, commercial buildings, utilities, and low-voltage distribution networks for reactive power compensation and system efficiency.
Exemptions Provided
- Products manufactured solely for export purposes,
- Items imported or made only for R&D, testing, or demonstration under specified conditions.
Industries Impacted
- Electrical utilities and power distribution companies,
- Industrial and commercial consumers,
- Electrical equipment and motor manufacturers,
- Importers, distributors, and dealers of capacitors.
Mandatory Compliance Requirements
- From 1st February 2018, no person can manufacture, import, sell, or distribute such capacitors without BIS certification. Products must bear the ISI mark and conform to IS 13340.
Next Steps for Stakeholders
- Manufacturers must apply for a BIS license under Scheme-I (ISI Marking) for IS 13340.
- Importers should ensure foreign suppliers are BIS-certified before shipment to India.
- Dealers and distributors must verify the ISI mark and license details before sale.
- Utilities and industries should update procurement policies to source only BIS-certified self-healing capacitors.
Legal Provisions, Enforcement & Penalties
- Governed by the BIS Act, 1986, enforcement is led by BIS and supported by state authorities. Non-compliance may result in seizure of goods, fines up to ₹50,000, imprisonment up to 1 year, or both.
Conclusion
Since February 2018, BIS certification under IS 13340 is mandatory for all self-healing power capacitors up to 650 V in India. The regulation improves safety, performance reliability, and energy efficiency in the power sector.
