Continuous, on-line partial discharge monitoring offers utilities a powerful tool to protect and optimize the performance of their assets. PD monitoring is the only practical method of determining the health of the complete GIS insulation system without intrusive inspections. Only the UHF method as developed by DMS can assure sufficient sensitivity and noise immunity to detect all types of PD defects in the GIS, including for example, low level PD in voids in solid insulation materials. The availability of reliable PD information, in conjunction with other switchgear and system parameters such as load currents, switching events, etc., enables realistic assessment of short and long term operational risks and lifetime expectations to be made.

• Pre-failure preventative action
• Significant reduction of costs
• Reduction of inspections and maintenance
• Prevention of expensive catastrophic failures
• Improved quality and reliability of power supply
• Extension of plant/transformer life

• When the installation has a critical function in the network such as at generation stations or key industrial loads
• When the plant may be at risk due to an extreme operating environment such as periodic overloading
• When the plant is reaching old-age, but a life-time extension is needed
• When a type failure mechanism (systemic defect) is suspected

The QUALITROL XPRD extra protection relief device is a mechanical overpressure protection device with integrated multidirectional discharge outlet. Designed by the original creator of automatically resealing pressure relief devices, the XPRD is the next generation in pressure relief with stainless steel construction, the highest flow rate during operation available, and an integrated directional shield.

The large outlet and directional shield provide maximum pressure relief in addition to insulating fluid containment with optional piping on transformers during overpressure conditions. This important feature means that in the event of an oil discharge one can safely, without compromising the protection of the transformer, shield oil and gas from workers and other equipment preventing potential disaster.

• Reduce - Environmental impact and clean up
• Protect - Workers and assets from dangerous hot oil and gas exhaust
• Flexible - Installation, features, and piping options for any application
• Durable - Corrosion resistant construction for long term reliability
