Cumulus, the platform that modernizes legacy construction and operations processes with AI-powered work instructions and real-time data from connected tools, announced the addition of connected insulation resistance (IR) testing to its core offering — beginning with direct integration to Megger electrical testing tools.
For decades, IR testing has been foundational to electrical quality in data center construction and commissioning. But even when the test was trusted, the trail wasn’t. Field crews recorded results by hand, QA teams transcribed data manually and project managers had little to no real-time visibility into whether critical electrical systems were actually ready for energization. At the exact moment projects need certainty, documentation introduced doubt.
Cumulus IR testing closes that gap, the company said. Test results transfer automatically from BLE-enabled Megger devices — beginning with the MIT1525/2, MIT1025/2, and MIT525/2 — directly to the Cumulus platform, capturing voltage, duration, technician, timestamp, and pass/fail status in real time, with no handwriting, no transcription and no paperwork lag. Workflows are defined in advance and pushed to field tablets, ensuring every test follows the approved procedure. Failed tests are flagged and tracked automatically. Commissioning-ready reports generate themselves.
Early implementation shows a 50% reduction in process completion time, with improved accuracy, audit-readiness and data accessibility across project teams.
“Cumulus was founded to prevent rework in mission critical construction and maintenance by replacing cumbersome paperwork with real time, worker-level data,” said Matthew Kleiman, CEO of Cumulus. “IR testing was the natural next step. Trusted tools are already in the hands of every electrician on these projects — what’s been missing is a way to capture that work digitally, instantly and without error. Now it exists.”
The launch marks the beginning of a broader platform expansion to connect trusted field-testing tools directly to the systems that prove quality. Megger is the first integration partner in this initiative, with additional BLE-enabled tool integrations planned as the category matures.
“Insulation resistance testing is a foundational step in verifying electrical infrastructure before energization, but the documentation process has traditionally been manual,” said Ahmed El-Rasheed, Industry Director at Megger Ltd. “Connecting test instruments directly into digital quality workflows helps ensure results are captured accurately and available to project teams in real time. Integrations like this represent an important step toward more connected commissioning practices across the industry.”
