Buchholz Relay & Breather Inspection
Our professional Buchholz Relay & Breather Inspection services ensure early fault detection, improved transformer safety, and reliable system performance. Both the Buchholz relay and breather system play critical roles in protecting oil-filled transformers from internal faults, moisture contamination, and gas buildup. Regular inspection helps prevent major failures and ensures uninterrupted operation.
The Buchholz relay is a key protection device that detects gas accumulation, oil level drops, and sudden pressure surges inside the transformer. Our experts thoroughly inspect its operation, test alarm and trip functionality, check float movement, and verify relay responsiveness. Similarly, the breather unit is examined for silica gel condition, moisture saturation, oil seal condition, and proper airflow to maintain transformer insulation health.
Over time, moisture saturation, oil leakage, trapped gases, or mechanical faults can affect the performance of these protection components. Routine inspection improves transformer reliability, ensures accurate fault detection, and reduces the risk of expensive breakdowns. Our service is ideal for industries, substations, utilities, and commercial installations.
Our Work Process
We follow a detailed Buchholz Relay & Breather Inspection process that begins with visual assessment, operational testing, and cleaning. For the Buchholz relay, we inspect gas collection, verify float operation, test alarm and trip circuits, and check oil levels. For the breather unit, we examine silica gel color, replace saturated material, inspect gaskets and seals, and ensure proper air filtration. All findings are documented for system health tracking.
- Inspection and testing of Buchholz relay alarm & trip functions.
- Verification of float movement and relay responsiveness.
- Silica gel replacement and breather condition assessment.
- Inspection of oil seals, gaskets, and moisture entry points.
- Early detection of gas formation, oil leaks, and internal faults.
