Gain accurate insights to maximise operational up-time.
There is an ever increasing range of transformer monitoring and diagnostics equipment available to the market that empowers asset managers with real time information.
With this broad range of asset information - connected online and available continuously - better decisions can be made to improve reliability, reduce maintenance expenses, proactively manage performance and delay or decrease capital expenditure.
Address Developing Faults
Comparing continuous data from online sensors means small changes and trends can be identified, allowing issues to be addressed before they become a problem.
Identify Premature Ageing
Closer monitoring of critical transformers enables action to be taken earlier, thus halting premature aging caused by untreated defects and loading patterns.
Vital Health Information
Gathering data from assets while they are operational offers
insight as to the health of these assets that offline testing simply
Reduce Unplanned Outages
Unplanned transformer outages or failures have the potential to interrupt service to thousands of customers.
Many smaller transformers are left unmonitored because the perceived benefits do not outweigh the system costs.
However there are many cases where smaller transformers can be critical to part of a network and where operational teams would benefit from key insights into the condition of these assets from online monitors.
On the technology side, there are a number of newer devices that offer lower cost entry into monitoring for exactly these situations. These include dissolved gas analysis, moisture and temperature information - the most critical in identifying problems or providing early warning.
Insulect can assist with evaluation and recommendations on what solution is best for your situation.
At the upper end of the spectrum, the biggest challenges are usually deciding what to monitor and how to best make use of available data.
Most critical large transformers will have multiple monitoring systems equipped, with all data being connected into a central "online" transformer management system.
Interpretation and analysis of this data is critical to successful asset management. Data overload and lack of experts’ time have
combined to dictate the need for intelligent analytic algorithms. Their role is to automatically evaluate the incoming data to determine the risk level and prioritise the need for a human expert to delve further into the data.

Water has long been challenging to manage because of the many ways it finds its way into transformers.
Hot spots are the critical points in the insulation that age fastest leading to failures.
DGA is the most effective method for identifying developing faults of all kinds.
Bushings are more susceptible to fail as they age, leak oil or due to moisture ingress.
There are numerous issues that can develop due to the mechanical action of OLTCs.
PD is an early sign of impending insulation failure and is getting growing attention.
DGA is accepted as the most effective method of transformer health assessment.
This is because the transformer oil contains 70-80% of transformer health information. When a thermal or electrical fault occurs in a transformer, the oil and paper insulation will break down generating gases that dissolve back into the insulating oil.
Dissolved Gas Analysis is the extraction and analysis of those gases for monitoring and diagnostic purposes. The types of gases present in the oil indicate the nature of the fault; the rate of increase of these gases over time indicates the developing severity of the fault.
