ATV1200-A110-6666 — Schneider Electric Altivar 1200 Medium Voltage Drive
The Schneider Electric Altivar 1200 is a medium voltage variable speed drive covering power ratings from 110 kW to 5000 kW at 2.4 kV, 4.16 kV, and 6.6 kV supply voltages, designed for large industrial motor drives in oil and gas, mining, water, and power generation where the motor size and voltage level make low-voltage VFD solutions impractical. The ATV1200 uses a multilevel neutral point clamped (NPC) power converter topology that produces a near-sinusoidal output voltage waveform with total harmonic distortion below 3%, eliminating the motor derating and insulation stress that conventional 6-pulse medium-voltage drives impose. The passive input rectifier provides less than 5% THDi on the supply side without external filtering, satisfying utility grid harmonic standards at the point of common coupling.
The ATV1200's modular power cell design enables N+1 redundancy through the optional cell bypass function: if a power cell fails during operation, the drive automatically reconfigures at reduced power rather than tripping completely, maintaining process continuity until the next planned shutdown. For Saudi Arabia's continuous process industries, this bypass capability is commercially worth many times the drive's original purchase price when it prevents an unplanned process shutdown in a refinery or desalination plant. The drive's sealed oil-cooled or water-cooled transformer and power electronics are qualified for ambient temperatures to 50°C, addressing Saudi Arabia's summer conditions without derating.
In Saudi Arabia, the Altivar 1200 KSA serves the large-motor end of the process drive market — applications where the motor is 750 kW to 5000 kW and operates at medium voltage. ARAMCO's gas turbine compressor helper drives, SWCC's large seawater reverse osmosis high-pressure pump trains, and Ma'aden's ball mill and SAG mill drives in the phosphate processing circuit are principal applications. SEC's large ID and FD fan drives in coal-substitute gas-fired power stations specify the ATV1200 for its output waveform quality.
Razz Middle East works with Schneider Electric's global MV drive engineering team to provide ATV1200 project support in Saudi Arabia, including transformer specification, harmonic study, civil preparation requirements, factory acceptance test witnessing, site commissioning, and long-term service contracts.

Key Features & Benefits
- Multilevel NPC topology produces near-sinusoidal output with less than 3% voltage THD, eliminating motor insulation stress and derating penalties that six-pulse MV drives impose on motor windings.
- Cell bypass redundancy option allows continued drive operation at reduced power after a single power cell failure, preventing unplanned process shutdowns worth millions of riyals per hour in refinery and desalination applications.
- Passive input rectifier achieves less than 5% THDi on the medium-voltage supply without external harmonic filters, satisfying IEC 61000-3-12 and IEEE 519 harmonic limits at the plant's point of common coupling.
- Modular power cell design simplifies maintenance: individual cells are plug-in replaceable during planned shutdown without special lifting equipment, reducing scheduled maintenance time versus monolithic converter designs.
- Oil-immersed or water-cooled transformer and power electronics rated to 50°C ambient covers Saudi Arabia's summer conditions without derating, maintaining full drive power rating year-round.
- Motor-friendly output eliminates the need for du/dt output filters or dV/dt reactors even on long cable runs between the drive and motor, reducing installation cost in large plant where cable runs exceed 100 m.
- Advanced motor protection functions including thermal modelling, partial discharge monitoring, and bearing current mitigation protect the high-value MV motor asset, extending rewind intervals in demanding duty cycles.
Industrial Applications in Saudi Arabia
- Gas turbine compressor helper and back-up drive systems at ARAMCO's gas processing plants, where the near-sinusoidal output protects the MV motor windings and eliminates EMC interference on plant instrumentation.
- Large seawater reverse osmosis high-pressure pump drives at SWCC desalination facilities, where cell bypass redundancy prevents plant-wide production loss during individual power cell maintenance.
- Ball mill and SAG mill main drives at Ma'aden Phosphate Company's Al Khali beneficiation plant, where the drive's low harmonic performance satisfies the mining complex's isolated grid power quality requirements.
- Induced draft and forced draft fan drives at SEC gas-fired power generation stations, where variable speed replaces IGV control and delivers fuel savings of 3–5% on station heat rate.
- Large crude oil transfer and export pump drives at ARAMCO's marine terminals, where medium voltage eliminates the large LV transformer and busduct infrastructure required for equivalent LV VFD installations.
- Refinery process air compressor and plant air compressor drives at ARAMCO and SABIC refineries, where continuous 24/7 operation at rated power demands the highest available drive reliability.
- Mine ventilation main fan drives at Ma'aden's underground phosphate mining operations in Wa'ad Al-Shamal, where variable speed maintains safe airflow velocity across the full range of mine production activity.
