What Is a Technical Audit of Electrical Infrastructure

A technical audit of electrical infrastructure is a systematic and documented assessment of the condition of electrical installations in a building or industrial complex. Unlike a routine inspection, an audit analyzes the installation as a whole: design, execution, current condition, compliance with applicable regulations, and suitability for current use.

The result is a detailed report that identifies deficiencies, evaluates risks, and proposes prioritized corrective actions. It is, in essence, a complete diagnostic of the electrical infrastructure.

When Is a Technical Audit Needed

Before a Renovation or Expansion

Any building renovation or expansion project should begin with an exact understanding of the existing installation’s condition. A pre-renovation audit answers critical questions:

  • Can the existing installation support the additional planned loads?
  • Which components must be replaced?
  • Does the existing documentation (diagrams, designs) reflect reality?
  • Are compliance upgrades needed before expansion can proceed?

Without this information, the renovation project risks building on an unreliable foundation.

After Incidents or Major Failures

A short circuit, an electrical fire, or repetitive equipment failure are clear signals that the installation requires a comprehensive evaluation, not just a localized repair. A post-incident audit seeks to:

  • Identify the root cause, not just the symptom
  • Assess the integrity of the rest of the installation (damage may be more extensive than visible)
  • Verify the effectiveness of protection devices (why they did not trip, or tripped insufficiently)
  • Prevent recurrence through structural recommendations

Change of Ownership or Tenancy

Transferring property ownership or leasing a commercial or industrial space involves legal responsibilities regarding the condition of electrical installations. An audit provides:

  • The buyer: a clear picture of the installation’s condition and required remediation costs
  • The seller: documentation attesting to the installation’s condition at the time of transfer
  • The tenant: certainty that the space is safe for the intended use
  • The landlord: legal protection through documented condition at handover

Periodic Compliance Inspections

Romanian legislation mandates periodic inspections of electrical installations. The frequency depends on the building type and use:

  • Public buildings (hospitals, schools, shopping centers) — more frequent inspections per specific regulations
  • Industrial buildings — based on the working environment and associated risks
  • Office buildings — periodic inspections per Normativ I7
  • Residential buildings (apartment blocks) — inspections at intervals set by the building administrator

Change of Building Use

Converting office space into a production facility, or an industrial hall into a retail space, fundamentally changes the requirements for the electrical installation. The audit evaluates the compatibility of the existing installation with the new intended use.

What Auditors Check

A comprehensive technical audit covers all components of the electrical installation:

Documentation

  • Existence and currency of as-built designs
  • Correlation between single-line diagrams and field conditions
  • Previous compliance certificates and inspection reports
  • Equipment documentation (data sheets, certifications)

Electrical Panels

  • Physical condition of panels (corrosion, damage, sealing)
  • Component compliance with the design
  • Circuit labeling and identification
  • Operating temperature (thermographic imaging)
  • Condition of connections and busbars
  • Available spare capacity

Distribution Circuits

  • Cable insulation condition (insulation resistance measurement)
  • Cable cross-section versus actual load
  • Cable routes (installation method, separation, mechanical protection)
  • Condition of junction boxes and intermediate connections

Protection Systems

  • Operation of circuit breakers and residual current devices
  • Protection selectivity (coordination between levels)
  • Condition and effectiveness of the earthing system
  • Surge protection
  • Lightning protection (if applicable)

Special Equipment

  • Uninterruptible power supplies (UPS)
  • Backup generators
  • Emergency lighting systems
  • Fire detection and alarm installations
  • Electrically powered access control systems

Regulatory Compliance

  • Normativ I7 — design, execution, and operation
  • PE 116 — testing and measurement
  • EN 61439 — electrical panels
  • Specific regulations for the building type (hospitals, retail, etc.)

What the Audit Report Contains

A professional audit report includes:

Installation Description

  • General installation diagram
  • Inventory of main equipment
  • History of known modifications

Findings and Measurements

  • Results of all measurements performed (insulation, impedance, earth resistance)
  • Identified deficiencies, documented with photographs
  • Comparison with current regulatory requirements

Risk Assessment

Each deficiency is classified by severity:

  • Critical — immediate danger, requires emergency intervention (risk of electrocution or fire)
  • Major — significant non-compliance, requires remediation in the short term (weeks)
  • Minor — deficiency with no immediate danger, but must be scheduled for remediation
  • Observation — improvement recommendation, no current risk

Action Plan

  • List of corrective actions, ordered by priority
  • Cost estimate for each action
  • Recommended completion timeline
  • Identification of work requiring ANRE certification

Benefits of Proactive Auditing

Companies that conduct regular technical audits — not just when forced by circumstances — gain concrete advantages:

  • Incident prevention — deficiencies are identified and remediated before they cause consequences
  • Cost optimization — planned repairs are always cheaper than emergency interventions
  • Continuous compliance — avoidance of fines and legal complications
  • Insurance validation — insurance policies are only valid when installations are compliant
  • Budget planning — the audit report enables accurate estimation of necessary investments
  • Updated documentation — the audit produces valuable documentation for any future intervention

How to Choose an Auditor

Not every electrician can perform a comprehensive technical audit. Look for:

  • ANRE certification type C (electrical installation verification)
  • Documented experience in your type of building or industry
  • Calibrated measurement equipment appropriate for the task (megohmmeter, thermographic camera, power analyzer)
  • Reference reports — request a sample previous report to evaluate quality and detail
  • Independence — the auditor should not also be the contractor for remediation work (conflict of interest)

A professionally conducted audit is an investment that pays for itself many times over through the problems it prevents.
