Understanding the R726's Three Core Functions

The Leroy Somer R726 module distinguishes itself through three integrated functions that work harmoniously to ensure reliable parallel generator operation. First, the power factor regulation capability allows your generator to operate efficiently when paralleled with utility mains power. This feature actively manages the phase relationship between voltage and current, ensuring your generator contributes optimally to the combined power system without creating harmonic distortion or power quality issues. This is particularly valuable for facilities that use generator power to supplement utility power during peak demand periods or for load shaving applications.

The second critical function is voltage equalization, which occurs automatically in the moments before paralleling operations commence. The R726 continuously monitors both the generator voltage and the target voltage (whether mains or another generator), then makes precise adjustments to ensure voltage levels match exactly before the paralleling breaker closes. This pre-synchronization prevents the damaging voltage spikes and mechanical stress that can occur when generators with mismatched voltages are connected. This protection extends the life of your alternator, switchgear, and connected loads.

Finally, the paralleling capability with other R726-equipped alternators enables you to create scalable power systems where multiple generators work together as a unified source. The R726 modules communicate and coordinate to ensure proper load sharing, frequency synchronization, and voltage matching across all units. This is essential for applications requiring redundancy, increased capacity, or the ability to bring generators online and offline without interrupting power to critical loads.

Compatible Alternator and Generator Models

The R726 AVR is specifically designed for integration with Leroy Somer alternator systems. This module is commonly found in the following applications and configurations:

• Leroy Somer LSA alternator series requiring parallel operation capabilities
• Multi-generator installations with synchronized load sharing requirements
• Mains parallel applications where generators supplement utility power
• Industrial power systems with multiple generating sets
• Critical power facilities requiring N+1 redundancy configurations
• Commercial buildings with combined heat and power (CHP) systems
• Data centers utilizing multiple generator sources for backup power
• Healthcare facilities with redundant emergency power systems
• Manufacturing plants with complex power distribution requirements

The R726 maintains full compatibility with the Leroy Somer R129 and R130 voltage regulators, allowing for mixed configurations within the same power system. This compatibility enables facility managers to upgrade existing systems or integrate new generating capacity without replacing all voltage regulation equipment. Whether you're retrofitting an existing installation or designing a new multi-generator system, the R726 provides the flexibility needed for sophisticated power architectures.

Installation Overview and Integration

Installing the Leroy Somer R726 module requires qualified electrical technicians familiar with generator control systems and parallel operation requirements. The module mounts directly to compatible Leroy Somer alternators using standard OEM mounting points and connects to the alternator's excitation system through designated terminals. Proper installation begins with complete system shutdown and lockout/tagout procedures to ensure technician safety.

The installation process involves several critical steps: First, the existing AVR (if present) must be carefully removed, with all connections documented for reference. The R726 voltage regulator is then positioned in the mounting location and secured using appropriate hardware. Electrical connections must be made according to the wiring diagram specific to your alternator model, with particular attention paid to sensing inputs, excitation outputs, and communication lines for parallel operation.

For parallel operation applications, additional wiring connects the R726 modules across multiple generators, establishing the communication network that enables synchronization and load sharing. Current transformer connections provide load sensing information, while voltage sensing connections from the bus allow the module to monitor system voltage accurately. After all connections are complete, the system requires careful commissioning, including verification of voltage regulation accuracy, parallel operation sequencing, load sharing balance, and protection system functionality.

While experienced technicians can complete R726 installation, we strongly recommend involving factory-trained service personnel for initial setup and commissioning of parallel systems. The complexity of coordinating multiple generators demands expertise in both the hardware connections and the parameter settings that optimize system performance. General Power can connect you with qualified service providers who specialize in Leroy Somer generator systems and parallel operation configuration.

Frequently Asked Questions About the Leroy Somer R726

What is the primary purpose of the R726 AVR module?

The Leroy Somer R726 serves as an advanced automatic voltage regulator specifically designed for generators that operate in parallel configurations. Unlike standard AVRs that only regulate voltage for a single generator, the R726 provides three integrated functions: power factor regulation for paralleling with utility mains, voltage equalization that matches voltage levels before paralleling occurs, and coordination capabilities allowing multiple R726-equipped alternators to parallel together. This makes the R726 essential for facilities that run multiple generators simultaneously, supplement utility power with generator power, or require redundant generating capacity with seamless load transfer capabilities.

Can the R726 work with other Leroy Somer voltage regulators in the same system?

Yes, the R726 module is fully compatible with the Leroy Somer R129 and R130 voltage regulators within the same power system. This compatibility allows you to integrate new generators equipped with the R726 into existing installations that may use different Leroy Somer AVR models. The R726's communication and synchronization capabilities enable it to coordinate with these other regulators, maintaining proper voltage matching and load sharing across the entire multi-generator system. This flexibility is particularly valuable when expanding generating capacity or upgrading portions of an existing installation without replacing all components.

How does the voltage equalization function work before paralleling?

The voltage equalization function of the R726 voltage regulator continuously monitors both the generator's output voltage and the voltage of the system it will parallel with (either utility mains or another generator). In the moments before the paralleling breaker closes, the R726 automatically adjusts the generator's excitation to bring its voltage to match the target system voltage precisely. This pre-synchronization process happens rapidly and automatically, preventing the voltage differential that would otherwise cause a current surge when the breaker closes. By eliminating these transient currents, voltage equalization protects switchgear, reduces mechanical stress on the alternator, and prevents voltage disturbances that could affect sensitive loads.

What technical expertise is required to install the R726?

Installing the Leroy Somer R726 AVR requires qualified electrical technicians with experience in generator control systems, preferably with specific knowledge of parallel generator operations. The installation involves mounting the module to the alternator, making multiple electrical connections including sensing circuits and excitation outputs, and establishing communication links between multiple generators for parallel operation. Beyond the physical installation, the system requires careful commissioning to verify voltage regulation accuracy, parallel synchronization, and load sharing balance. While experienced generator technicians can perform the installation, first-time R726 installations benefit significantly from involving factory-trained service personnel who understand the nuances of parallel system setup and optimization. General Power can help connect you with qualified service providers in your area.
