TRANSFO ACCESSORY

Measure, Monitor and Prevent

Sensors and Thermometers

The quality of measurement directly impacts equipment lifespan. Our transformer sensors are integrated into windings for precise hotspot monitoring, while the transformer thermometer provides immediate readings of oil or enclosure temperature. This allows you to obtain valuable data to anticipate thermal drifts and adjust load levels without compromising service continuity.

Temperature Relays and Oil Level Indicators

Avoid overheating and cooling failures using temperature relays (temperature monitoring and protection) combined with an easy-to-read oil level indicator. Connected to supervision systems, these transformer components provide essential alarm thresholds and status feedback required for incident prevention, from unexpected trips to accelerated insulation wear.

Dielectric Oils, Filtration and Containment

Ready-to-Install Filtration Kits

The characteristics of dielectric oils change over time. A complete filtration kit (prefilter, valve, fittings, Teflon tape, etc.) simplifies preventive maintenance and reduces particles or moisture that may affect performance. Designed for quick intervention, these assemblies fit existing installations to preserve the electrical and thermal characteristics of the fluid.

Pits and Containment Basins: Capture, Filter and Control

For transformer safety and site protection, pit filtration and containment basin filtration help manage accidental spills and comply with environmental requirements. Combined with drainage and monitoring accessories, these systems support clean and compliant operations, particularly for outdoor substations and sensitive areas.

Grounding and Substation Safety

Grounding Systems and Equipotential Bonding

Grounding systems remain a cornerstone of electrical installation accessories. Our MALT grounding braids ensure reliable connections for fault current dissipation and personnel protection. Additionally, junction terminals, connectors, and equipotential bars structure the entire interconnection network for safe operation, even in the presence of electrical disturbances.

Site Organization and Mechanical Accessories

Mechanical stability is just as important as electrical performance. SanerBlock® wheel locking brackets prevent unwanted transformer movement during handling operations. This type of transformer accessory contributes to risk prevention both in workshops and on-site, alongside suitable protective and safety equipment.

Connection and Insulation: Choosing the Right Components

Terminals, Insulators and HV/LV Accessories

For clean and durable connections, select transformer terminals and transformer insulators suitable for your circuit requirements. Our high-voltage accessories and low-voltage accessories provide electrical and mechanical performance compliant with standards, while ensuring simplified installation for both field operations and planned maintenance.

Frequently Asked Questions

Why use transformer monitoring equipment?

Transformer monitoring equipment helps maintain optimal operating conditions and prevents failures. Devices such as temperature sensors, thermometers, and temperature relays provide real-time operating data to identify abnormal conditions before they affect equipment performance or reliability.

What is the purpose of dielectric oil filtration?

Dielectric oil filtration removes contaminants such as moisture, particles, and degradation residues that may reduce insulation properties. Proper filtration extends transformer lifespan, improves electrical performance, and reduces the risk of insulation failures.

Why are containment systems important for transformers?

Containment systems are designed to collect accidental oil leaks and prevent environmental contamination. Combined with filtration solutions, they help protect the surrounding area, comply with environmental regulations, and improve operational safety.

What is the role of grounding systems in substations?

Grounding systems provide a safe path for fault currents and help protect personnel and equipment against electrical hazards. Proper grounding also improves system stability and reduces the impact of electrical disturbances.

How do I choose the right transformer accessories?

The choice depends on several factors, including transformer type, operating environment, load requirements, maintenance conditions, and applicable standards. Selecting compatible transformer accessories ensures reliable performance, simplified maintenance, and long-term equipment protection.
