Services for Instrument Transformers
Internal dielectric strength degradation is the main risk affecting the lifetime performance of an instrument transformer. Contributing to 70% of the failures, it can ultimately cause a fire or explosion that can damage nearby high voltage assets. The degradation can be due to overheating, short circuit, oil leakage from gasket deterioration caused by tough environmental conditions, or the humidity contained in oil-impregnated cellulose insulation.

Benefit of Working With The “Disruptive” Team With Extensive Expertise
Studies are delivered by GE Vernova’s Subject Matter Experts based in the Global Technology Center. The team is active in international working groups and delivers lectures at technical conferences including CIGRÉ, Matpost, IEEE, CEIDP, IEC.
The GE Vernova materials and eco-design team members have filed over 35 patents in the last 15 years and bring disruptive technologies to the industry, examples include:
DWatch
Intelligent Monitoring and Control of Disconnectors
GE Vernova's DWatch performs permanent real time monitoring of the operational parameters of disconnectors and records all operating curves locally.
The DWatch also controls the speed of the live part during opening and closing in a specific and programmable manner for all disconnector types. These profiles can be easily set by internal dip-switches. Such control helps in always having a constant operating time in different conditions of power supply and load.
