Major corporate and regulatory decisions are made on a daily basis using data produced by testing laboratories. Since test results are a vital component of most conformity assessment projects, it is critical to obtain accurate test data.

The first step in assuring accurate and reliable test results is selecting the right lab.

eti operates two labs that are uniquely focused on the power industry and meet important IEEE, ANSI and MIL specs. They cover a wide range of measurements and are fully portable to field locations.

Calibration
All eti field test instruments are regularly calibrated to primary and secondary standards traceable to the National Institute of Standards and Technology (see our traceability chart).

• High Voltage, AC and DC up to 100,000 volts
• High Current up to 10,000 amps AC, 1,500 amps DC
• Instrument and meter calibration, analog and digital: amps, volts, ohms, to 100 parts per million, phase angle
• Time and Frequency: picosecond to megahertz
• Temperature: Direct, simulated and low infra-red
• Pressure: Hydraulic and gaseous to 10,000 psi
• Dimensional: Distance and weight

Forensic Evaluation
eti conducts failure investigations and forensic evaluations after equipment failure, personal injury or electric shock. We carefully examine the equipment and events that took place and construct a fault tree to analyze possible failure mechanisms. We perform tests to determine the most probable or root cause of a failure or accident and provide scientific evidence to support our conclusion.
