In the highly demanding and unforgiving environment of high-voltage substations, every millisecond counts, and every protective measure must be rock-solid. When it comes to ensuring safety, continuity, and protection of critical equipment like circuit breakers, transformers, and generators, the Arteche BI-16R Lockout Relay stands out as a truly game-changing solution. This heavy-duty electromechanical relay offers exceptional performance in triggering and blocking applications where both actuation speed and breaking power are non-negotiable.

With over six decades of experience, Arteche has built a global reputation for delivering high-quality, high-reliability power system components. Among its expansive product lineup, the BI-16R Lockout Relay (LOR) has become a staple in modern substation safety and control systems. Let’s explore why this relay is earning accolades worldwide and how it brings significant value to substation applications.

Arteche BI-16R Lockout Relay: The Heart of Substation Safety

Lockout relays, designated as ANSI 86, are essential safety components in protection and control schemes. Their primary function is to “lock out” equipment after a protective relay has operated, ensuring that no further closing or re-energization occurs until the fault condition is cleared and the relay is manually or electrically reset.

In simple terms, a lockout relay is like a safety gate that shuts down equipment to prevent repeated tripping or dangerous re-energization. It adds a layer of fail-safe logic to protect not only the equipment but also the integrity of the entire power system.

The Arteche BI-16R takes the lockout relay concept several steps forward. Purpose-built for high-speed, high-power applications, the Arteche BI-16R Relay is a plug-in type electromechanical relay featuring:

• 16 Inverter Contacts (16PDT Form-C)
• Compliance with major international standards: IEC 61000, IEC 60947, IEC 60255, and ANSI C37.90
• Low and High Burden Configurations per ESI 48-4 EB1 & EB2: 1983
• Type I Base Compatibility for modular installations

Key Features of the BI-16R

Let’s delve into the standout features that make the Arteche BI-16R relay a leader in its category.

• High Breaking Capacity: The Arteche BI-16R Relay is designed to interrupt high currents safely and consistently. This capability is essential in preventing arcing or damage when the relay disconnects control circuits during fault conditions.
• Fast Operating Time (3 – 20 ms): Speed matters when protecting high-voltage systems. The BI-16R responds within 3 to 20 milliseconds, ensuring that faults are isolated almost instantaneously. Additionally, it reduces potential damage and improving system recovery time.
• 16 Contact Configuration: With 16 inverter-type Form-C contacts, the BI-16R offers versatile switching options to control multiple downstream devices or systems from a single relay action. This makes it highly effective in complex control and automation schemes.
• High Dielectric Strength: This ensures galvanic isolation between control and power circuits, minimizing the risk of electrical interference, arcing, or insulation breakdown.
• Mechanical Latching and Manual/Electrical Reset: After the operation, the BI-16R relay remains latched until a manual or electrical reset command is issued. This feature prevents inadvertent reclosure and ensures that operators address the root cause of the fault before restoring service.
• Rugged Construction: Built to withstand vibration, shocks, and seismic conditions, the BI-16R is ideal for environments where mechanical resilience is critical.
• Wide Voltage Options: Arteche offers a variety of auxiliary voltage ratings, making the BI-16R compatible with a broad range of system requirements across geographies and utilities.
• High Burden Configuration for Long Wiring Runs: With EB2 classification under ESI 48-4, the relay is less susceptible to false trips from induced voltages or transients in long control wiring — a common issue in remote installations.

Benefits of the Arteche BI-16R Lockout Relay for Substation Applications

The Arteche BI-16R Lockout Relay delivers numerous tangible benefits for utilities, industries, and infrastructure providers who need reliable protection and seamless operation.

• Enhanced Safety: The lockout function prevents reclosing or further operations after a fault unless manually or electrically reset. This significantly improves personnel and equipment safety.
• Reduced Downtime: By acting quickly and precisely during a fault, the relay helps isolate issues before they cascade through the system, allowing faster troubleshooting and resolution.
• High Reliability in Critical Situations: With its robust design and dependable performance. However, the BI-16R ensures that protection schemes do not fail when they are needed most.
• Long Life Cycle: Arteche relays are known for longevity. The Arteche BI-16R Relay continues to perform reliably even under continuous operation and extreme conditions, reducing maintenance costs and downtime.
• Application Flexibility: Its extensive contact configuration, auxiliary voltage options, and compliance with global standards make it adaptable for various substation designs and retrofit scenarios.

Common Applications of the Arteche BI-16R Lockout Relay

• High Voltage Substations: To isolate circuit breakers or transformers during faults and prevent re-energization.
• Bulk Power Generation Plants: For locking out generator circuits upon detection of critical alarms such as low oil pressure, high temperature, or insulation faults.
• Industrial Power Systems: In facilities like chemical plants, refineries, or steel mills, where safe shutdown of electrical systems is paramount during emergency conditions.
• SCADA-Controlled Grids: As part of the command/control circuits, ensuring that faults do not trigger cascading events.
• Retrofit and Modernization Projects: As a reliable replacement for obsolete or underperforming relays in aging infrastructure.
