Switchgear Oil Diagnostics

Optimise Maintenance intervals with Live Tank Oil Sampling (LTOS)

Live Tank Oil Sampling (LTOS) is a unique and cost-effective technique for sampling switchgear units, offering significant benefits in minimising switching requirements.

Proven to cut costs, minimise disruption and improve reliability

Conventional switchgear maintenance, based on regularly shutting down equipment for inspections, can reduce reliability, increase health and safety risks and cause unnecessary downtime and disruption.

Yet research proves that the clear majority of these units would operate safely and reliably for many years, without any additional maintenance.

Maintaining oil-filled 11kV switchgear using a time-based schedule can result in considerable wastage, as not all the equipment will require maintenance.

In fact, EA Technology research shows that in a typical switchgear population, over 90% will be operating normally and require no maintenance. Live Tank Oil Sampling allows customers to identify which assets require attention and which are operating normally. This allows them to take remedial action with the minimal of disruption to switchgear operations.
