Scope of work can include supplying new or replacement gauges, mounting gauges on tank, running line for temperature probe, modifying tank to add probe well, wiring from control box to gauges, calibrating the equipment and verifying operation.


Oil and nitrogen leaks are a nagging problem found on many power transformers. Due to extreme operating and environmental conditions, leaks do occur at gaskets, fittings, welds and points of physical damage. Most leaks are repairable, and EDAM Service has the ability to find leaks and make those repairs. Some of our resources include experienced personnel; equipment necessary to handle, store oil and vacuum-fill; certified, experienced welders and specialized processes/procedures to remedy all kinds of transformer leaks.

In addition to repairs, EDAM has the equipment, experience and capabilities to complete other service work you may elect to perform while your transformer is being repaired, such as condition assessments, insulation dryouts, bushing replacements, LTC repairs/upgrades, natural ester retrofill, etc.; combining services can minimize costs and transformer downtime.


If your transformer includes an automatic load tap changer (LTC), our expert technicians will troubleshoot and repair the entire system including the controls, driver motor and contacts. Our testing of these devices will include the transformer turns ratio test (TTR) at all tap positions. Due to the large number of tap positions, this commonly exceeds thirty tests and we evaluate them all! To minimize your downtime, we have developed extensive resources to supply replacement components for these complex devices.

Many of your transformers are equipped with a no-load tap changer. When de-energized, this allows the transformer turns ratio to be manually adjusted to accommodate the varying conditions in your power system. While these systems are typically simple, they do cause issues that require immediate attention. We repair the contacts of these units or eliminate the weak link from your system by creating dependable physical connection.
