This case study covers a lightning protection assessment at a cement factory in Raipur — the same facility covered in this project’s earlier cement factory water audit case study, and the first of two additional Elion service lines documented at this client within this batch (alongside a companion ESG audit). As explained in this project’s Hyderabad pharmaceutical plant lightning protection content, this assessment evaluates an existing protection system’s adequacy against IS/IEC 62305 requirements — air termination coverage, down-conductor continuity, earthing adequacy, and surge protection device placement — distinct from the lightning arrestor design service covered at a Ballarpur paper mill elsewhere in this project, which engineers a new system rather than assessing an existing one. Cement factories present a particular structural consideration for this assessment given the characteristic height of raw material storage silos and kiln structures, which create elevated strike risk points requiring specific air termination coverage verification, similar in principle to the tall pulping tower and silo structures covered in the paper mill lightning arrestor design content, though here the assessment evaluates whether existing protection adequately covers this facility’s specific silo and kiln geometry rather than designing coverage from scratch. The assessment checked air termination coverage against the facility’s actual structure heights and layout using rolling sphere or mesh method verification, down-conductor path continuity, and earthing system adequacy. Raipur’s position within Chhattisgarh’s cement and steel industrial belt, covered elsewhere in this project’s cement factory water audit content, provides regional context. A lightning protection assessment for a cement factory of this scale and structural complexity typically costs ₹1.5–4 lakh. This case study covers what the assessment found across the facility’s tall structures.
This lightning protection assessment at the same Raipur cement factory covered for water audit elsewhere in this project checked air termination coverage against the facility’s tall silo and kiln structures — evaluating existing protection adequacy, distinct from the lightning arrestor design (engineering a new system) covered at a Ballarpur paper mill elsewhere in this project.

FAQs
Q1: How much does this assessment cost?
The cost of a lightning risk assessment / lightning protection assessment depends on the structure’s size, height, occupancy, location, surrounding exposure, existing lightning protection system, and the level of engineering documentation required. Elion currently lists its Lightning Risk Assessment service at ₹30,000 per day, while a project-specific quotation may vary depending on scope.
Q2: How does this relate to Elion’s water audit at the same facility?
The two assessments address different risk and resource areas but can form part of a broader multi-discipline facility assessment. A water audit evaluates consumption, distribution losses, water balance, reuse opportunities, and compliance, whereas lightning assessment evaluates the facility’s exposure to lightning and adequacy of protection measures. Elion offers both disciplines as independent engineering assessment services.
Q3: How does this differ from lightning arrestor design?
A lightning risk assessment determines the facility’s lightning risk and helps establish the required protection level and protection measures. Lightning protection design then translates those requirements into the physical system—such as air terminals, down conductors, bonding, and earth termination arrangements.
In other words, the assessment answers “what level of protection is required and why?”, while design answers “how should that protection system be configured?” Elion’s lightning risk assessment includes evaluation of structure type, occupancy, geographic location, exposure, and risks to people, assets, and service continuity.
Q4: What does IS/IEC 62305 require?
IEC 62305 provides the framework for lightning protection and lightning risk management. A key principle is that protection requirements should be based on a risk assessment rather than simply installing a lightning rod because a building is tall. The assessment considers risks such as loss of human life, service interruption, and damage to physical assets.
Elion identifies IEC 62305 as the applicable lightning-protection standard and uses it for lightning protection assessment and testing, alongside relevant Indian standards such as IS 3043 and IS 2309 depending on scope.
Q5: Why do tall structures need particular attention?
Tall and exposed structures have greater exposure to lightning because they can become prominent strike points, particularly where they extend above surrounding buildings or are located in open areas. Telecom towers, high-rise buildings, tanks, process vessels and other elevated structures therefore require careful consideration of air-termination coverage, down-conductor paths, bonding, earthing, and protection of connected electrical/electronic systems.
