Usage criteria between 32-STEP REGULATORS and DYNAMIC VOLTAGE REGULATORS (DVR)
32-Step Medium Voltage Regulators
Main Features:
1. Regulation Precision: These units have 32 discrete regulation steps, each approximately 5/8% of nominal voltage, allowing precise regulation of +/-10%.
2. Compatibility: Designed to operate in overhead and underground medium voltage distribution networks, in single-phase or three-phase configurations.
3. Custom Programming: Can be programmed to maintain voltage levels within defined limits, adapting to the specific needs of each network.
4. Versatile Mounting: Available in pole, pedestal, platform, and substation mounting versions.
5. Interconnectivity: Compatible with SCADA systems and network automation, facilitating remote monitoring and control.
6. Robust Construction: Sealed tank, insulating fluid sight glass, overvoltage protection (MOV), and pressure relief systems.
When to use them:
• Supplies with moderate fluctuations: Ideal for areas requiring constant voltage adjustments due to load variations.
• High consumption networks: In industrial or commercial areas with variable demand.
• SCADA compatibility: When real-time remote monitoring and control is needed.
• Standard medium voltage supplies:To comply with power quality regulations and avoid penalties for voltage issues.
Dynamic Voltage Regulators (DVR)
DYNAMIC VOLTAGE REGULATORS are advanced solutions based on grid-connected inverter technology and energy storage using supercapacitors, designed to protect equipment sensitive to voltage fluctuations and drops.
1. Ultra-fast response: Designed to protect against voltage sags, swells, and momentary faults (including zero-voltage interruptions), with response times of 100 μs and effective protection in 3 ms.
2. Energy storage: Use supercapacitors instead of batteries, ensuring efficient, low-maintenance protection.
3. High energy efficiency:With efficiency up to 99%, significantly reducing operating costs.
4. Industrial capacity: Built for demanding environments, handling severe disturbances without compromising load protection.
5. Operating modes:
• Standby: Operate normally while the network is stable.
• Protection: Activate stored energy to power critical loads during disturbances.
• Recovery: Return to normal mode when the network stabilizes.
• Maintenance bypass:Allow disconnection for technical interventions.
6. No interruptions: Ensure sensitive loads experience no voltage drops or momentary interruptions.
• Environments with critical loads: Industries with sensitive processes (electronics, pharmaceutical, manufacturing) where any voltage drop can cause damage or financial losses.
•Unstable supplies: Areas prone to frequent voltage drops, surges, or momentary interruptions.
•Priority energy efficiency:When seeking a system with low operating cost impact and greater durability.
• Alternative to industrial UPS: In applications where prolonged energy storage is not required, but immediate protection is.
