Gulf Union Ozone supplies six power factor correction and power quality product families for Saudi Arabia industrial, commercial, and process plant electrical systems — all designed to comply with SEC Distribution Code power factor and harmonic limits, with free power audit before every system recommendation.

Type 01

Fixed Capacitor Banks

Three-phase LV (400 V) and MV (6.6–33 kV) fixed capacitor banks in kvar ratings from 25 to 600 kvar; improve power factor for fixed-load Saudi industrial processes and distribution substations. Fixed capacitor banks are the most cost-effective PFC solution for Saudi plants with constant or slowly varying reactive power demand — such as fixed-speed induction motor drives, arc furnace transformers at steady load, or distribution substation buses with predominantly inductive load. LV banks use IEC 60831-1 self-healing metallised polypropylene capacitor elements with built-in overpressure disconnectors. MV banks (6.6 kV, 11 kV, and 33 kV) use dry-type or oil-filled capacitor units in enclosed switchgear cubicles, with current-limiting HRC fuse protection. Gulf Union Ozone stocks standard LV fixed banks (25, 50, 100, 200, 400 kvar) for same-day dispatch from Jeddah.

Type 02

Automatic PFC Panels

Microprocessor-controlled APFC relay panels with 6–12 capacitor steps; maintain power factor between 0.95 and unity in response to variable loads at Saudi factories, water treatment plants and industrial complexes. APFC panels continuously monitor the reactive power demand at the metering point using a built-in current transformer and voltage sensing circuit, and switch capacitor steps in or out to maintain the target power factor set by the relay (typically PF = 0.95–1.00 lagging). Each step uses a contactless thyristor switch (TSVC) or conventional contactor with detuned reactor. Gulf Union Ozone assembles 400 V APFC panels with 6, 8, 10, and 12 steps in ratings from 50 kvar to 600 kvar at its Jeddah facility, with type-tested enclosures (IP41 indoor, IP54 outdoor), dispatch in 2–3 weeks, and commissioning support across Saudi Arabia.

Type 03

Detuned Reactor Sets

Series-connected reactors (p = 7%, 14%) fitted with capacitor banks to suppress 5th and 7th harmonic resonance; mandatory where VFDs, UPS systems or rectifiers create harmonic distortion in Saudi electrical systems. A detuned (series reactor) capacitor bank has its resonant frequency shifted below the dominant system harmonic — a p = 7% reactor tunes the bank to 189 Hz (below the 5th harmonic at 250 Hz for 50 Hz systems), preventing parallel resonance with system inductance at harmonic frequencies. This eliminates capacitor overload, nuisance tripping, and fuse failure that occur when plain capacitor banks are used on Saudi electrical systems with significant VFD or UPS populations. Gulf Union Ozone supplies detuned reactor-capacitor sets as matched units in ratings from 25 to 600 kvar; reactors are air-cooled, encapsulated dry-type with Class H insulation for Saudi 50°C ambient service.

Type 04

Harmonic Filters

Passive C-type and active harmonic filters for THD reduction below 5% at the point of common coupling; required to meet Saudi SEC (Electricity and Cogeneration Regulatory Authority) power quality limits. Passive C-type harmonic filters are tuned to specific harmonic frequencies (5th at 250 Hz, 7th at 350 Hz, 11th/13th at 550/650 Hz) and also provide reactive power compensation at fundamental frequency — combining PFC and harmonic filtering in a single unit. Active harmonic filters (AHF) inject an anti-phase harmonic current into the electrical system to cancel the harmonic currents injected by VFDs, UPS units, and rectifiers, reducing total harmonic distortion (THD-I) to below 5% regardless of load variation. Gulf Union Ozone supplies active harmonic filters in 50 A, 100 A, and 150 A ratings for connection at LV panel bus, suitable for Saudi Aramco, SABIC, and HADEED steel plant electrical systems.

Type 05

Power Analysers

Portable and panel-mount power quality analysers measuring PF, THD, kW, kvar, kVA, harmonics (H2–H50), flicker, dips and swells; essential for Saudi plant power audits before PFC installation. Accurate measurement of the power factor and harmonic content at the metering point is the essential first step before specifying any PFC system — specifying capacitors on a plant with high harmonic content without measurement risks resonance and capacitor failure. Gulf Union Ozone supplies IEC 61000-4-30 Class A analysers (the highest accuracy class, required for SEC tariff disputes and official power quality compliance testing) and Class S analysers for general plant surveys. Portable loggers are deployed for Gulf Union Ozone's free 48-hour power audit; panel-mount analysers with RS-485 Modbus are available for permanent installation at Saudi industrial LV distribution boards.

Type 06

Reactive Power Controllers

Smart APFC relay controllers with RS-485 Modbus or Ethernet interface, LCD display and data logging; available with SCADA integration for real-time power factor monitoring at Saudi distribution panels. The reactive power controller (APFC relay) is the intelligence of an automatic PFC panel — it continuously measures reactive current demand, calculates the required capacitor switching steps, and activates or deactivates contactors or thyristor switches to maintain the target power factor. Gulf Union Ozone supplies microprocessor-based APFC relays with 6- and 12-output versions, LCD display for local kvar and PF readout, RS-485 Modbus RTU or Ethernet TCP/IP communication for SCADA integration, and internal data logging of PF, kvar, and capacitor switching events. Compatible with all leading capacitor contactor brands; suitable for Saudi Aramco and SABIC plant DCS integration.

Frequently Asked Questions

Power Factor Correction in Saudi Arabia — Common Questions

What power factor does Saudi Electricity Company require at the metering point?

Saudi Electricity Company (SEC) Electricity Distribution Code (EDC) requires industrial customers to maintain a minimum power factor of 0.90 lagging at the point of metering during peak and off-peak periods. Customers with PF below 0.90 are subject to reactive power charges on their SEC electricity bill. For large consumers (above 1 MVA), the SEC also enforces harmonic distortion limits (THD voltage ≤ 5%, individual harmonic ≤ 3%) per IEC 61000-3-12. Gulf Union Ozone designs APFC and harmonic filter systems to meet both PF and THD requirements simultaneously.

Why are detuned reactors necessary when installing capacitor banks with VFDs?

Variable frequency drives (VFDs), UPS systems and other non-linear loads inject 5th and 7th harmonic currents into the electrical system. If uncorrected capacitor banks are connected to the same busbar, they can resonate with system inductance at the harmonic frequency, causing capacitor overload, nuisance fuse blowing and switchgear tripping. Detuned reactors (series inductors) shift the capacitor bank resonant frequency below the dominant harmonic (typically to 189 Hz for a p=7% reactor, below the 5th harmonic at 250 Hz). Gulf Union Ozone always audits the harmonic environment before specifying PFC equipment on Saudi plants with VFD installations.

What is the payback period for power factor correction in a Saudi industrial plant?

Payback on a Saudi PFC installation depends on reactive power charge tariff, kvar demand and PFC equipment cost. At current SEC tariffs (approximately SAR 0.05–0.10/kvarh reactive energy charge), a 500 kvar APFC panel costing SAR 45 000 installed typically achieves payback in 12–18 months. Plants with large induction motor loads (pumps, fans, compressors) and PF below 0.80 see the fastest payback. Gulf Union Ozone provides a written payback calculation before quotation, based on the customer's SEC electricity bill and the measured power factor from the free power audit.
