Overview

3. Usage Features
4. Maintenance Features

The Selec 900VPR-U is a comprehensive voltage and frequency monitoring relay designed for 3-phase electrical systems. It offers a wide range of protection features, precise measurement capabilities, and user-friendly configuration options, making it suitable for various industrial and commercial applications.

Function Description

The 900VPR-U continuously monitors electrical parameters in 3-phase, 3-wire, or 4-wire systems. Its primary function is to protect equipment from voltage and frequency anomalies, including:

• Over Voltage (OV): Detects when voltage exceeds a set limit.
• Under Voltage (UV): Detects when voltage drops below a set limit.
• Over Frequency (OF): Detects when frequency exceeds a set limit.
• Under Frequency (UF): Detects when frequency drops below a set limit.
• Phase Asymmetry (AS): Monitors the imbalance between phases.
• Phase Failure (PFL): Detects the loss of one or more phases.
• Neutral Loss: Monitors for the absence of the neutral connection.
• Phase Sequence Monitoring: Ensures correct phase rotation.

Upon detection of a fault, the device activates one or both of its two independent alarm relays (Relay1 and Relay2), providing output signals for control or indication. The device also incorporates adjustable time delays for Power ON, Trip Time, and Recovery Time, allowing for customized response to transient conditions and preventing nuisance tripping.
