High-performance lightning arresters engineered for the demanding keraunic levels and fluctuating grid infrastructure of Togo and the Gulf of Guinea.
Togo is rapidly establishing itself as an economic hub in West Africa, driven by the expansion of the Autonomous Port of Lomé, substantial investments in rural electrification, and a fast-developing renewable energy sector. The country's solar development goals, supported by organizations like the Agence Togolaise d'Electrification Rurale et des Energies Renouvelables (AT2ER), are bringing utility-scale projects online, such as the 50MW Sheikh Mohamed Bin Zayed solar power plant in Blitta.
However, Togo’s sub-Saharan tropical climate yields a high keraunic activity index, characterized by severe seasonal thunderstorms and intense lightning. Furthermore, instability on the national power grid (CEET) frequently leads to sudden voltage surges, causing structural and operational damage to sensitive electronics, industrial motors, and solar inverter arrays. Implementing reliable, high-specification Surge Protective Devices (SPDs) is a critical technical requirement for local electrical installations, safeguarding capital assets and reducing network downtime.

Step inside Bowser Electric’s state-of-the-art production facility, where precision engineering meets rigorous quality standards.
Choosing the right technological baseline for complex power distribution grids in West Africa.
Features fast response times (typically <25ns) and high current diversion capability. Designed with thermal disconnection mechanisms to prevent thermal runaway in high-temperature sub-Saharan environments.
Provides high isolation resistance with virtually zero leakage current. Highly recommended for N-PE protection paths in TT and TN-S grounding configurations commonly found in Togolese infrastructure.
Integrates MOVs and GDTs in series to eliminate leakage currents, prevent varistor degradation, and extend the operating life of the device on weak grids prone to sustained overvoltages.
Explore our range of low-voltage AC and high-voltage DC protection devices, fully certified for global compliance and demanding grid requirements.
Whether protecting off-grid microgrids in rural northern Togo or utility-scale plants in Blitta, PV installations require dedicated DC surge protection. Under IEC 61643-31, SPDs used in solar systems must withstand specific open-circuit voltages up to 1000V or 1500V DC. Our DC SPDs feature standard DIN-rail mounting options, rapid-acting varistor configurations, and built-in thermal disconnections that prevent failure under severe ambient heat.
The Autonomous Port of Lomé operates continuous logistics terminals, automated cranes, and processing machinery. Voltage drops and spikes from the regional grid can cause expensive downtime. Installing Type 1+2 (Class I+II) hybrid SPDs at the main distribution panels ensures protection against direct lightning strikes, while Type 2 units installed downstream protect PLC controllers, communications devices, and variable speed drives.
The global lightning protection industry is shifting toward digitalization. Modern facilities implement "Smart SPDs" equipped with dry contacts or RS485 communication protocols (such as Modbus). These systems monitor the health of internal varistors and track lightning event history in real time. This allows facility operators in Lomé to schedule preventive maintenance before an SPD reaches its end of life, ensuring uninterrupted system protection.
Designing coordinated, multi-stage lightning and transient protection architectures.
Installed at the main low-voltage switchboard (MDB) where the external power lines enter the building. Designed to handle direct lightning impulses ($10/350\ \mu\text{s}$ waveform) and prevent dangerous surges from entering the internal distribution network.
Located at sub-distribution boards to limit overvoltages caused by switching events or residual energy from Stage 1 surges. Standardized for $8/20\ \mu\text{s}$ waveforms, protecting general machinery, lighting, and air conditioning systems.
Installed close to sensitive equipment (servers, PLCs, telecom systems). Features low voltage-protection levels ($U_p$) to ensure transient overvoltages are clamped safely below the dielectric withstand limit of the connected hardware.
