Tan Delta Electric Corporation has its own Oil Testing Laboratory to conduct various tests to ensure reliability of the transformer oil.

We offer technologies, methods, and services that address the entire solution for insulating oil.

Thermal scanning is one of the preemptive methods used by Tan Delta Electric Corporation for preventive maintenance of different electrical equipment. It plays a big role in avoiding future electrical equipment failure.

Thermal heating, also known as hotspot, affects the insulation of wires and it could result to oxidation due to excessive heating. If neglected, it can cause a major factor that could affect the operation of the whole electrical system.

Tan Delta Electric Corporation is one of the pioneer in the application of infrared/thermal scanning services in the Philippines, having a U.S. trained Certified Level 1 & 2 Thermographer and licensed engineers with extensive experience in various electrical and mechanical equipment and/or installations.

UDT (Ultrasonic Detection Testing) is your first line of defense against unplanned downtime. Electrical faults such as arcing, tracking and corona discharge emit ultrasound signals at the site of the failure, often without generating any heat. The use of it is to hear what you cannot see.

It can detect partial discharge at its infancy before it advances to an arcing or tracking condition. Tan Delta Electric Corporation pioneered in year 2002 the application of Ultrasonic Detection services in the Philippines. Inspection is being carried-out by our in-house engineer and certified Level -1 Ultrasonic Inspector trained in the U.S.

Tan Delta Electric Corporation vacuum oil purification and regeneration rigs can be used to process oil on online or offline transformers. Our rigs can process up to 6000 Liters Per Hour, and because the transformer is energized, the customer never has to take an outage

We offer oil regeneration where oil is being restored to its original properties and to be used equally “as new” so replacement is not necessary. Regenerated transformer oil is the best quality, environmental and economic choice for transformer installation and maintenance.

Tan Delta Electric Corporation has its own Repair and Calibration group composed of skilled electronic specialists who ensures that your equipment is accurate and calibrated through the use of highly technical calibration devices and modern software.

Calibration improves the accuracy of the measuring and testing equipment.

Our lightning protection products includes Exothermic Welding (E plus Series) and Resistance Reducing Agent. For our grounding solution includes Copper Bonded Steel Rod, Clamp, and other grounding accessories.

A good grounding system provides certain level of safety to humans and properties in case of equipment damages.

Our training and technical support facilities is so far the most complete in the Philippines, with a wide ray of test specimens (138kV and 69kV Power Transformer, CVT, CT, PT, SF6, Power CB, LA, Bushing CT, Protection relays and others) and electrical testing equipment.

The facility also houses our transformer oil processing equipment such as vacuum oil purifiers, oil regeneration system and SF6 gas recovery equipment.
