Taiwan Power Company has purchased more than 200 MSENSE® DGA 3 sensors from Reinhausen to replace the competitor’s failed TDCG (total dissolved combustible gas) devices, according to information released by Reinhausen.
Online oil analysis devices play a key role in the analysis of the operational safety of oil-filled, paper-insulated power transformers. They make a measurable impact on extending the service life of transformers, as they are the most powerful option of detecting and analyzing errors in the windings of a transformer.
These benefits were also well-known to Reinhausen’s customer Taiwan Power Company (TPC) when they decided to equip their more than 2,000 power transformers with online DGA (dissolved gas analysis) sensors over ten years ago. For the 69kV to 345kV segment, TPC chose very simple DGA sensors, so-called “smoke detectors”, which only measure the total dissolved combustible gas (TDCG) share in the transformer oil. Generally, these devices are very inexpensive, but they can only provide a very vague picture of the transformer condition.
Within few years, TPC had installed over 1,000 units of this inexpensive online DGA from an unnamed world market leader, Reinhausen said. Over the years, unfortunately, TPC discovered many problems with their smoke detectors: Defective displays, wrong alarms and other failures were daily routine and caused high internal costs.
TPC was therefore looking for a working new online DGA monitoring solution that would also be technically more sophisticated and would search through at least two fault gases. Around the same time MR introduced its MSENSE® DGA3, which provides the following measuring components:
This was exactly what TPC were looking for. Only a short time later a pilot installation was implemented and TPC was convinced of the performance spectrum of the MSENSE® DGA3.
Convinced by these unique advantages, Taiwan Power Company has already purchased more than 200 MSENSE® DGA 3 sensors to replace the competitor’s failed TDCG devices.
Reinhausen added that it was looking forward to continuing this success story with the first deliveries of its new MSENSE® DGA 5/9.
