Predictive Maintenance

NFPA 70B-2023
Doesn't Blur Lines

Condition-based maintenance is now mandatory for owners and operators of critical electrical equipment. Time-based schedules no longer satisfy the standard.

VIE addresses six mandatory NFPA 70B-2023 clauses directly. No infrastructure overhaul. No equipment shutdowns. Operational within one to two days of first installation.

The Shift from Time-Based to Condition-Based Maintenance

Maintenance has operated on schedules for decades. Annual oil tests. Quarterly inspections. Power factor testing once a year. The intervals felt reasonable. They were not built around how transformers actually fail.

Transformer degradation is continuous. It does not wait for a scheduled sample window. Winding looseness, insulation loss, overheating oil, and partial discharge all develop between inspection cycles. By the time a scheduled test detects them, the failure window is often closing.

NFPA 70B-2023 closes that gap by mandate. The standard requires risk-based, prescriptive, condition-based maintenance for critical electrical assets. It requires documentation. It requires continuous monitoring where economically justifiable.

Every electric utility, data center, and industrial operator with critical transformer infrastructure is now inside that requirement.

Why Conventional Methods Miss the Window

Every monitoring method has a detection window. The question is where that window sits relative to failure.

In one documented case, VIE identified a fault that a recent DGA test had cleared as healthy. The two methods are not redundant. They are complementary. VIE detects what DGA cannot.

See how VIE and DGA work together

VIE continuous monitoring

Detects thermal and mechanical fault signatures weeks to months before the failure event. It issues an actionable alert while there is still time to plan, source parts, and schedule a repair.

Online DGA

Detects arcing and high-energy electrical events, but with a narrow alert window. Thermal degradation and paper aging require months of trend data before the signal becomes actionable.

Periodic oil sampling

Only detects a problem if a sample happens to fall inside the failure window. Lab turnaround adds additional delay after collection.

Annual power factor testing

Tracks insulation degradation over years. It provides no real-time visibility between test cycles.

Megger testing

Measures degradation that already exists. It does not detect precursors.

SFRA

Identifies winding deformation, but only after a physical event has already occurred.

VIE detects failure modes 3 to 6 months before the failure event — across electrical, mechanical, and thermal fault categories simultaneously.

NFPA 70B-2023 Clause Alignment

KPMG modeled ROI across three failure rate scenarios at a three-year horizon. The results ranged from 96% in the baseline case to 373% in the adverse case. At the empirically observed failure rate of 1.79%, the model returned 178% ROI.

NFPA70B Clause

How VIE Meets It
4.2
Maintenance documentation must be accessible and up-to-date
VIE auto-logs all transformer health data with timestamps, complete audit trails, and on-demand export
5.2
Assets must be prioritized based on criticality for operations, safety, and reliability
VIE lets operators monitor their most critical transformers first and scale across the fleet overtime
9.1.2 and 9.2
Predictive maintenance methods, including vibration and thermal analysis, shall be used where applicable
VIE captures tri-axial vibration and multi-point surface temperature at multiple external locations on every monitored transformer
9.2.3
Use of remote monitoring systems is encouraged to reduce exposure to hazards
VIE delivers real-time remote monitoring, reducing the need for physical inspections of energized equipment
11.3
Condition-based monitoring is required when economically justifiable
VIE delivers 3-10x ROI in months, validated across 700+ transformers globally
Annex D
Technologies such as thermal, electrical, and environmental sensors should inform maintenance
VIE includes multi-parametric sensing across environmental, electrical, and mechanical stressors

VIE is one of the few commercially available systems that is field-deployable without downtime, built specifically for transformer monitoring, and capable of generating audit-ready maintenance documentation on demand.

The Rapid Compliance Pathway

Moving to documented, condition-based monitoring under NFPA 70B-2023 does not require a months-long project. The full pathway from zero to compliant runs in one to two days.

Step 1

Identify critical transformers.

1 day. Prioritize assets by operational and safety risk. Start with the transformers your fleet cannot afford to lose. Per Clause 5.2.

Step 2

Install VIE sensors.

Under 30 minutes per transformer. External mounting only. No de-energization.No modifications to transformer internals.

Step 3

Connect to the cloud.

Same day. The myVIE dashboard connects via LTE or satellite. No existing network infrastructure required at the site.

Step 4

Set alert thresholds and auto-logging.

1 to 2 hours. Configure alert parameters. Confirm automated health log generation is active.

Step 5

Generate reports and trend analysis.

Instant. The platform produces digital logs, risk rankings, and condition trends from the moment sensors go live.

Step 6

Export audit-ready documentation.

On demand. Download formatted compliance documentation for NFPA 70B inspectors at any time.

From first sensor to documented compliance: one to two days.

  • Access the myVIE dashboard from any web browser or mobile device

For Your Executives

Strategic Oversight

  • Meet the mandatory NFPA 70B-2023 CBM requirement with a single platform
  • Produce audit-ready maintenance documentation on demand, at any time
  • Monitor fleet-wide risk exposure across distributed assets in one view
  • Defend ROI with a KPMG-validated benchmark: 3-10x return delivered in months

The NFPA 70E Connection: Worker Safety

NFPA 70B-2023 is the compliance trigger. Worker safety is the underlying reason the standard exists.

VIE monitors electrical stress indicators continuously. It detects high harmonics, partial discharge, and arcing signatures early. Early detection of these conditions reduces the risk of the electrical failures that cause arc-flash events.

NFPA 70B addresses equipment reliability. NFPA 70E addresses worker safety. VIE supports both.

Frequently Asked Questions

Is NFPA 70B-2023 actually mandatory?

Yes. The 2023 edition changed the standard’s status from a recommended practice to a mandatory requirement. Owners and operators of critical electrical equipment must now implement risk-based, condition-based maintenance programs with documented results. Consult your compliance counsel for jurisdiction-specific applicability details.

Does VIE generate the documentation NFPA 70B inspectors require?

Yes. The myVIE platform automatically logs every transformer health data point, alert, and maintenance event with timestamps and full audit trails. Reports export on demand in formats suitable for compliance review.

Does VIE work on transformers already in service?

Yes. VIE sensors install on the external surface of any transformer — wet or dry, any make, model, voltage, or vintage. The transformer stays fully energized throughout the entire installation process.

How long does it take to become compliant?

A typical deployment moves from first sensor installation to a fully operational, documented monitoring program in one to two days. Full machine health baselines are established for each asset within 30 days.

Does VIE also support NFPA 70E compliance?

VIE is not a dedicated arc-flash safety system. The platform does continuously monitor electrical stress indicators — including partial discharge and arcing signatures — that, when detected early, reduce the conditions that lead to arc-flash events. That monitoring aligns with the hazard reduction intent of NFPA 70E.

The Compliance Clock is Running.

NFPA 70B-2023 is in effect. Every month of time-based maintenance is a month of documented non-compliance and undetected risk in a fleet that can no longer afford either.

VIE is field-deployable today. Documentation is automated from day one. The compliance case is already built.
