Advanced Harmonic Studies

ETAP-Powered Analysis for Power Quality, G5/5 Compliance & Electrical System Performance

At Pendulum Power Consultants, we specialise in harmonic studies, providing expert analysis to ensure power quality, system stability, and compliance with ENA G5/5 regulations. As electrical networks become more complex with the integration of renewable energy systems, industrial loads, and high-efficiency power electronics, managing harmonics is essential for maintaining reliable and efficient electrical infrastructure.

Harmonic Studies – Ensuring Power Quality & Compliance

Our team of power system consultants and electrical engineers leverages advanced tools like ETAP to conduct ENA G5/5 Stage 2 & 3 harmonic assessments, ensuring your electrical systems meet UK grid compliance standards. We support 11kV, 33kV, and 132kV networks, helping industrial, commercial, and renewable energy clients mitigate harmonic distortions, voltage fluctuations, and equipment stress.

Comprehensive Harmonic Study Services

At Pendulum Power Consultants, we provide detailed harmonic analysis to prevent power quality issues, equipment malfunctions, and regulatory non-compliance. Our services include:

  • ENA G5/5 Stage 2 & 3 Harmonic Assessments
    Ensuring compliance with UK distribution and transmission standards.
  • Harmonic Distortion Analysis
    Identifying and quantifying voltage and current harmonics affecting your network.
  • Filter Design & Mitigation Strategies
    Developing solutions such as passive and active harmonic filters to reduce distortions.
  • Power Quality Audits
    Conducting in-depth assessments to diagnose waveform distortions and non-linear loads.
  • Grid Code Compliance for Renewables
    Ensuring that solar farms, wind farms, and battery storage projects meet ENA G99 and harmonic compliance standards.
  • Resonance & Frequency Analysis
    Assessing grid impedance interactions to prevent harmonic amplification issues.

Harmonic Studies & ETAP Simulation

Using ETAP, we perform highly accurate harmonic modelling, simulation, and compliance verification, enabling us to:

  • Predict harmonic levels before equipment installation.
  • Model harmonic mitigation solutions such as filter design and tuning.
  • Ensure compliance with G5/5 and historical G5/4 standards.
  • Assess worst-case harmonic injection scenarios to ensure grid stability.

Our harmonic analysis services help businesses optimise system performance, reduce downtime, and protect critical infrastructure from power quality issues.

Modern Slavery & Human Trafficking Statement

PPC Ltd is committed to preventing modern slavery and human trafficking in all areas of our business and supply chain. We operate solely within the UK, providing consultancy and technical services to the energy and power sector. Our supply chain includes specialist subcontractors, UK-based service providers and technical equipment suppliers.

We have a zero-tolerance approach to modern slavery and uphold this through:

 

Our Policies & Responsibilities

  • A formal Modern Slavery and Human Trafficking Policy (HR-010)
  • Clear responsibilities for Directors and senior management
  • Annual policy review and company-wide communication
  • Integration with our ISO-aligned management systems

 

Supplier Due Diligence

We assess and monitor suppliers through our approval process, including checks on controls relating to modern slavery. Higher-risk suppliers—such as those outside the UK/EU—are subject to enhanced scrutiny. We will not work with any organisation involved in slavery or trafficking.

 

Training & Awareness

Employees receive induction awareness, access to our modern slavery policy, and ongoing updates. Additional training is provided for those involved in procurement and supplier management.

 

Risk Management

We monitor risks in our supply chain and found no evidence of modern slavery during this reporting period. We continue to improve our assessment processes and supply chain visibility.

 

Reporting Concerns

Employees can report concerns through management or our formal reporting procedures. All reports are investigated, and breaches follow disciplinary actions as defined in HR-010.

 

Continuous Improvement

In 2025 we will strengthen supplier assessments, expand training, and ensure this statement remains up to date and transparent.

This statement has been approved by the Director and is published in accordance with the Modern Slavery Act 2015.
