State of the Art - Quality Testing

GESS power systems are thoroughly tested adhering to ISO 9001 standards to ensure maximum reliability, maintainability and safety. This is how longterm operational efficiency and high protection are sustained for mission critical processes at the moment of truth.

Digital Oscilloscope, Power Analyzer, Digital Multimeter, True RMS Multimeter, DC Loads, AC Loads, Variable Transformers, Temperature props, Heating & Cooling Test Rooms, Humidity Test Rooms, Noise Level Measurement, High Voltage Isolation Tester and Current & Voltage Harmonic Tester are among the devices used to run final quality tets to ascertain longterm reliability of the systems.

Thanks to quality checks for each component during the regular manufacturing processes, the final quality testing is completed with maximum safety mainly with 10 phases as shown in the diagram on the next page.

Tests Under Extreme Conditions
Main routine tests includes but not limited to standard tests. To ensure utmost reliability, the systems are subjected to extreme conditions as well:

  • A gallon of water is splashed on to devices in case of their exposure to rain while in use
  • Systems are exposed to fire to ascertain that no single component flames
  • Devices are dropped from a half-a-meter altitude to ensure that systems continue to function even after.
1 - Load Capacity Test
The device's performance levels are measured at full load. The questions like how well the device protects the load when input voltage spikes or how the protection components (ie. thermistor) reacts to instant climatic changes at full load are examined.

2- Input Current Harmonics Test
Input current and voltage values are measured and rated against the criteria by the harmonic tester device.

3 - Output Distortion Test
Harmonic distortion, current & voltage parameters are measured against the preset criteria by the distortion meter and power analyzer.

4 - Input Voltage Range Test
Variable transformers are put in place to simulate input voltage tolerances.

5 - Vibration Test
Mechanical vibration is applied to each system to make sure the devices are safe against any probable oscillation during transportation to customers.

6 - Short Circuit Test
Off-limits current & voltage are applied to systems at full load and they are expected to safeguard the load by showing short circuit behavior.

7- Noise Level Test
Although GESS power instruments use "intelligent fan Control system", final testing is done with noise level measurement at 1 meter distance to control the noise level under 60 db.

8 - Over Voltage Test
High voltage isolation tester is used to simulate over voltage conditions and device’s functionality and reliability are measured & examined under tough conditions against the standards.

9- Temperature & Humidity Test
Products are placed in the heating & cooling test rooms to examine their functionality under 90% humidity and at temperature +50 degree celcius.
