BIS Certification for Switchgear and Controlgear Equipment Operating Above 1000 Volts
In today’s increasingly electrified world, high-voltage switchgear and controlgear equipment play an indispensable role in energy distribution, industrial operations, and infrastructure development. Designed for safe and reliable control of electricity at voltages exceeding 1000 volts, these systems are critical for minimizing risks and ensuring seamless power flow in high-demand applications. With rising concerns about electrical safety and equipment standardization, the Bureau of Indian Standards (BIS) has taken decisive steps to regulate this sector through the Scheme X Certification.
Let's explore the scope, necessity, and compliance process for BIS certification for switchgear and controlgear equipment operating above 1000 volts, providing stakeholders with all the insights required to meet India’s latest regulatory standards before the 28th August 2025 deadline.
What Is High-Voltage Switchgear and Controlgear?
High-voltage switchgear and controlgearrefer to electrical apparatus that controls, protects, and isolates power systems above 1000 volts. These devices are fundamental in grid substations, large industrial plants, renewable energy systems, and transmission networks.
Key components include:
- High-voltage circuit breakers
- Disconnectors and earthing switches
- Gas-insulated switchgear (GIS)
- Vacuum and SF6 switchgear
- Surge arresters
- Instrument transformers (for measuring and protection)
- Metal-enclosed and metal-clad switchgear assemblies
These components operate inelectrically intensive environments, handling high fault currents, ensuring personnel safety, and maintaining equipment integrity under extreme conditions.
Introduction of BIS Scheme X Certification
To standardize the design, safety, and quality of such critical infrastructure equipment, theBureau of Indian Standards (BIS)introducedScheme X Certificationunder theBIS Conformity Assessment Regulations, 2018. This certification framework was launched on16th March 2022and is tailored for:
- Electrical machines and components
- Switchgear systems
- Machinery with specialized industrial functions
Recognizing the strategic importance of high-voltage systems in India’s energy and industrial ecosystems, theMinistry of Heavy Industriesissued theOmnibus Technical Regulation Order, 2024, makingScheme X certification mandatoryfor all manufacturers of relevant equipment—bothdomestic and international—from28th August 2025onward.
Why BIS Certification Is Critical for High-Voltage Switchgear
The implementation of BIS certification for switchgear and controlgear equipment (above 1000V) is not merely a regulatory exercise—it’s a national safety priority.
Key reasons include:
- Electrical Safety: Prevent arc faults, short circuits, and insulation failures.
- Operational Continuity: Prevent unplanned outages in power grids and industrial setups.
- Product Quality Assurance: Enforce strict conformance to Indian Standards (IS).
- Market Standardization: Create a level playing field for domestic and foreign manufacturers.
- Environmental Compliance: Promote eco-friendly switchgear solutions (e.g., low-SF6, vacuum tech).
Scope of BIS Scheme X for High-Voltage Equipment
The certification applies to:
- All switchgear and controlgear systems operating at voltages above 1000V
- Individual devices, assemblies, sub-assemblies, and critical components
- Products used in generation, transmission, and industrial control systems
Manufacturers, importers, OEMs, and system integrators must comply with the applicable standards for both thefinal productand itsmajor components.
Certification Process: Step-by-Step Guide
1. Determine Applicability
Confirm whether your product falls under the BIS mandatory list as per Scheme X. Products with rated voltages above 1000V used in switching, controlling, or isolating electrical circuits are included.
2. Technical Documentation Preparation
This includes:
- Detailed product specifications
- Test reports
- Material and component traceability
- Manufacturing flow chart
- Quality management system documents
- Safety and performance data sheets
3. Application Filling
Apply on theBIS online portal, specifying Scheme X and attaching all supporting documentation.
4. Product Testing
Representative samples are submitted toBIS-recognized laboratoriesfor testing as per relevant IS standards. Testing evaluates:
- Insulation and dielectric strength
- Mechanical operation and endurance
- Thermal behavior
- Short circuit performance
- Environmental resistance (temperature, humidity, dust)
5. Factory Inspection
A BIS inspection team visits the manufacturing site to audit:
- Production setup
- In-house testing capabilities
- Quality control procedures
- Packaging and labeling systems
- Calibration of instruments
6. License Granting
Upon successful testing and inspection, BIS issues theScheme X certification license, enabling manufacturers to affix theISI mark.
Compliance Deadline
- Final Date for Mandatory Compliance:28th August 2025
- Recommended Timeline to Begin Certification: As early as possible, ideallyQ2 2024, considering test queues and audit timelines.
Benefits of BIS Scheme X Certification for High-Voltage Equipment
Benefit | Description |
Legal Authorization | Legal approval to market or supply high-voltage switchgear in India |
Safety Assurance | Enhances personnel and system safety in high-risk electrical environments |
International Recognition | Compliance with Indian standards aligned with IEC provides global credibility |
Consumer Trust | ISI mark builds confidence in power utilities, government buyers, and EPC contractors |
Tenders & Bids | BIS certification is often apre-qualification criterionfor public sector tenders |
Environmental Compatibility | Encourages adoption of eco-friendly designs like vacuum breakers and dry-type insulation |
Consequences of Non-Compliance
Failure to obtain BIS certification for switchgear and controlgear equipment by the stipulated deadline can result in:
- Seizure or recall of non-certified products
- Prohibition from participating in government tenders
- Legal penalties under the BIS Act, 2016
- Damage to brand credibility and market trust
- Potential delays in commissioning large infrastructure projects
Conclusion
India’s push for quality, safety, and self-reliance in electrical infrastructure is gaining momentum through robust frameworks like the BIS Scheme X Certification. For manufacturers of high-voltage switchgear and controlgear equipment, the 28th August 2025 deadline is a significant milestone.
Early compliance not only ensures uninterrupted business but also boosts product trust, regulatory credibility, and market access. Whether you're a large OEM, EPC contractor, or system integrator, now is the time to begin the certification process and align with India’s future-ready infrastructure goals.
