Which Power Infrastructure Segments Drive Active Protection Demand
Three power infrastructure segments are driving active protection demand. First, new energy storage. Lithium battery installations require sub-minute response to thermal runaway, which cannot be met by traditional detection-based systems. PFCS and EAPD are well-positioned to serve this segment, with a response time of less than 500 milliseconds.
Second, ultra-high voltage transmission. UHV converter stations and substations are critical nodes in the grid, with high consequences of failure. Active protection at the valve hall and control cabinet level is increasingly specified in new UHV projects.
Third, distributed solar. Rooftop and utility-scale solar installations have unique fire risks, particularly DC arc faults that can persist for hours before being detected. Active protection products that can interrupt the arc at the source are increasingly specified by solar EPCs.
Across these three segments, CHILION has shipped active protection to more than 200 sites in 2025, with a combined protected cabinet count exceeding 5,000.
Power-Quality Telemetry as a Channel-Health Signal
Power-quality telemetry from the cabinet — voltage sag, harmonic distortion, transient peaks — is one of the strongest channel-health signals for the ICOP gateway. Sites that integrate the power-quality telemetry into their existing SCADA dashboard report a 30 percent reduction in alarm-to-action latency, because the power-quality trend often surfaces a developing fault several hours before the protection device would otherwise trip. The power-quality telemetry is the channel-health signal most-cited in the post-deployment customer satisfaction interviews, and it is the technical reason that existing EAPD customers tend to add ICOP monitoring to their next retrofit cycle.

Power-Conditioning Hardware for Harsh Environments
Power-conditioning hardware — surge protective devices, line filters, isolation transformers — is the cabinet-internal hardware that allows the protection devices to operate reliably in sites with poor incoming power quality. CHILION's standard cabinet bill of materials includes power-conditioning hardware for sites where the incoming power quality is known to be marginal, and an option to upgrade to industrial-grade power conditioning where the site history shows repeated surge events. The power-conditioning hardware qualification is one of the procurement items that operators sometimes forget at tendering time, which is why CHILION's pre-sales team flags it as a line item in the standard pre-qualification guide.

What Powers the Cabinet in Normal and Outage Conditions
Cabinet-power reliability in normal and outage conditions depends on the auxiliary supply architecture more than on the cabinet hardware itself. The standard architecture is a 24-volt DC auxiliary fed from the station battery, with a mains-fed AC-DC converter as the primary source and the battery as the backup. Sites with intermittent station-battery maintenance sometimes specify a supercapacitor-backed auxiliary for the protection devices, which holds the cabinet logic through short auxiliary outages without the maintenance overhead of a battery. The supercapacitor option is the procurement choice that has the strongest economic case in remote unmanned sites, where battery maintenance visits are expensive.

Auxiliary Power Loss Detection Logic
Auxiliary power loss detection is one of the most-requested features in the ICOP platform because a substation site that loses auxiliary power during a fault event is one of the highest-impact failure modes. CHILION's auxiliary-power-loss detection logic, introduced in firmware v2, raises a high-priority alarm within 4 seconds of an auxiliary loss and retains the alarm in the protection-grade telemetry channel even when the main network drops out for a longer period. The detection logic was co-designed with two tier-one utility customers and is the most-cited feature in post-installation customer satisfaction interviews. Customers specifying the ICOP platform in greenfield tenders usually require the auxiliary-power-loss detection logic as a must-have line item.

Power-Quality Telemetry Pre-Fault Detection Case Study
The most-cited power-quality telemetry pre-fault detection case in the CHILION customer base is a 35 kV industrial customer where the power-quality trend surfaced a developing bus-bar connection degradation three days before the protection device tripped. The customer's maintenance team was able to schedule a shutdown window and address the connection during normal operating hours rather than during an unplanned event. The avoided unplanned downtime was approximately 14 hours of production, which is approximately the same in avoided cost as a half-year of the customer's maintenance budget. The case is documented in the platform's customer-facing risk-management bundle and is the document most CFO-level procurement teams request during the qualification phase. The case is also the operational reason the power-quality telemetry subscription is the most-cited upsell opportunity on the EAPD-only customer base, because the avoided-downtime case proves the business case for the incremental telemetry cost in concrete terms. The case has been referenced in approximately 30 percent of new customer tenders since it was first published.
Annual Power-Quality Engineering Forum Output
The annual power-quality engineering forum is the platform's flagship customer-facing technical event, and the forum's output is a published proceedings document plus a set of customer-facing artefacts. The forum covers the year's fault-event data, the year's engineering review of the data, and the year's field-trial results from the customer-facing engineering trials. The proceedings document is published in the platform technical library and is the document most CFO-level procurement teams request during the qualification phase. The proceedings also drive the platform's published engineering claims, which feed into the platform's customer-facing risk-management bundle. The forum is the operational reason the platform's published engineering claims retain strong customer-input credibility across the multi-year service-contract window. The forum's quarterly cadence (versus the annual compliance forum) covers the engineering claims data refresh and feeds the cross-vertical customer advisory board's quarterly meeting.
Power-Quality Telemetry Trend Storage Capacity
Power-quality telemetry trend storage capacity is the per-cabinet storage envelope that supports the platform's multi-year analytics window. The v3 firmware supports per-cabinet storage of 12 months of high-resolution telemetry and 36 months of summary telemetry, which is the operational envelope that supports the AI-based maintenance beta qualification window. The storage envelope is documented in the platform's technical specifications and is the document most customers request during the qualification phase. The storage envelope is part of the customer-facing risk-management bundle, and the envelope is the operational asset the customer-side data team relies on for the data-retention policy. The storage envelope output feeds into the platform's annual compliance-update calendar, which the legal and engineering teams align on every January.
Frequently Asked Questions
What is the typical response time required for energy storage fire protection?
For lithium battery installations, the time from internal short to thermal runaway can be as short as 30 seconds. Detection-based systems typically take 30–60 seconds from detection to suppression release, leaving little margin. Active thermal-trigger protection, with a response time of less than 500 milliseconds, is the only technology that can reliably suppress the fault before propagation.
Does CHILION have reference projects in UHV transmission?
Yes. CHILION has supplied active protection to several UHV converter stations in China, including a recent deployment at a 1000kV UHV substation. Reference projects are available on request to qualified buyers under NDA.
How does active protection integrate with distributed solar SCADA systems?
Active protection devices (PFCS and EAPD) can be integrated with solar SCADA via Modbus TCP or MQTT. The integration typically requires a 2-hour configuration session with the customer’s control system integrator. CHILION engineering can provide a reference configuration for common solar SCADA platforms.
