Sampling

TFSS®

Turbulent Flush Sampling System®

TJ|H2b has developed the Turbulent Flush Sampling System (TFSS®) for promoting a turbulent flush of the drain valve and facilitating the collection of a representative sample from electrical equipment.

The TFSS® is a compact, self- contained system which comes with quality parts and adapters to fit all types of sampling valves. It eliminates the need for funnels, pans, and bags and its design allows for easy sampling from low-clearance valves.

Without standardized collection equipment it is difficult to determine how much oil has been flushed from the drain valve. The TFSS® containment vessel markings make it easy to meet the recommended flush volumes and obtain a representative sample of the oil inside the equipment, not the contaminates that have settled into the valve.

BENEFITS

The TFSS® Kit provides several benefits

Promotes turbulent flush

Standardizes flush volumes

Produces representative samples

Prevents sample contamination

Reduces occurrence of accidental spills

GSCU

Gas Sampling Collection Unit

Proper sampling of Sulfur Hexafluoride (SF6) is critical to an accurate diagnostic assessment. TJ|H2b has stablished a sampling procedure that utilizes a Gas Sampling Collection Unit (GSCU) which permits samples to be collected free of interfering moisture and oxygen. The proprietary GSCU has been designed to allow maintenance personnel to obtain a gas sample safely and easily from circuit breakers and GIS.

This compact, two-cylinder device eliminates the need for SF6 collection devices that require using vacuum pumps. The GSCU is designed to maintain vacuum or pressure to meet normal shipping and handling requirements. This time-proven service for testing SF6 significantly reduces the cost of breaker maintenance.

BENEFITS

The GSCU provides several benefits

Promotes proper flush

Standardizes sample volumes

Produces representative samples

Prevents sample contamination

Reduces occurrence of environmental release

One of the most important concerns companies face when it comes to the testing of high-voltage electrical equipment is a result that accurately indicates the condition of the equipment. When evaluating test results, we make inferences about data that are based upon our collective experiences. These inferences are drawn from magnitudes of changes, in associations of relationships, within the test results. However, the underlying assumption is that the variance in test results from differing sample collection practices is negligible. In reality, we observe that a poorly drawn or contaminated sample can in fact negate the validity of a test result and even lead to a potential misdiagnosis.

The key to an accurately diagnosed sample is to ensure that proper sampling equipment and methods are used at all times. TJ|H2b has developed the TFSS® and GSCU for this reason. Additionally, TJ|H2b recommends following industry standard practices for sampling electrical insulating fluids (ASTM D923) and provides glass syringes and bottles free of charge for your sampling needs.
