Delta Power Quality Solutions

Advanced Power Conditioning for Reliable & Efficient Electrical Systems

Modern electrical systems rely heavily on advanced power electronics to improve efficiency and performance. However, these same technologies can introduce power quality issues that negatively impact grid stability, equipment reliability, and operational efficiency.

Delta Power Quality Solutions are designed to eliminate harmonics, stabilize reactive power, correct imbalance, and enhance overall power system performance, ensuring a clean, reliable, and efficient power supply for industrial, commercial, and infrastructure applications.

Why Power Quality Matters

Applications using rectifiers, variable frequency drives (VFDs), UPS systems, and other non-linear loads are growing faster than power grid infrastructure. As a result, power systems increasingly face challenges such as:

  • Voltage and current harmonics

  • Reactive power fluctuation

  • Three-phase imbalance

  • Voltage amplitude and frequency instability

  • Reduced power factor and higher energy losses

These power quality problems threaten the reliability, efficiency, and lifespan of electrical equipment while increasing energy costs and downtime risks.

To adapt to modern electronic loads and evolving grid conditions, it is essential to actively correct power quality disturbances rather than relying on passive solutions.

P1

ACTIVE HARMONIC (POWER) FILTER

Delta’s PQC Series APF is connected in parallel with non-linear loads, and uses one set of current transformers (CT) to detect the load current.
P2

STATIC VAR GENERATOR (SVG)

The principle of the SVG is very similar to that of Active Power Filter, as demonstrated in the picture below. When the load is generating inductive or capacitive current it makes load current lagging
