PD Detection Using NL Camera: Pros and Cons

pd-detection-nl-camera-pros-cons

Partial discharge is one of the first indicators of an upcoming failure in electrical powers system components. In fact, detecting partial discharges at an early stage enables proactive maintenance; and reduces the risk of catastrophic failures and expensive interruptions in the supply of power.

Partial Discharge Detection Methods

In fact, there are three nondestructive partial discharge detection methods which you may find the following list.

  • Acoustic methods: Conventional ultrasonic probes, and acoustic cameras: They can be used for PD detection; but are very limited for this purpose.
  • Thermal cameras (IR): They have some limitations for PD detection. For example, they only certain PD types, typically at a very late stage.
  • Ultraviolet cameras (UV): They have some limitations in PD detection, such as the requirement for a direct line of sight.

Next, let’s see a compared table of the features of NL Acoustic Camera and the other acoustic cameras.

NL Acoustic Camera Conventional ultrasonic methods Other acoustic cameras
PD localization Yes No Yes
PD recognition Yes (Listen to manually with headphones) No
PRPD pattern Yes No No
PD type classification Yes No No
Detection distance Up to 130 meters Typically up to 20 meters Typically up to 50 meters
Required training Minimal Extensive Extensive
Other The only acoustic camera with extensive analysis and severity assessment and recommended actions Not very practical without analysis

Typically very limited detection range due to high detection frequency range

Not very practical without analysis

PD Detection: NL Camera versus other acoustic cameras

In brief, NL Acoustic Camera for PD detection offers the following convincing advantages:

  • Includes real-time analytics for PRPD pattern
  • Severity assessment with recommended actions
  • Various software options for different needs
  • Better range: scan a larger area fast saving time and money
  • Better sensitivity
  • Light, one-hand held, rain-proof
  • Multi mode: detect several simultaneous partial discharges
  • Automatic frequency selection for optimal frequency range
  • Automatic data export
  • Uses the whole screen for detecting and analyzing PD

And, other acoustic cameras for PD detection lack the following features:

  • Do not include real-time analytics for PRPD pattern
  • No advanced severity assessment with recommended actions
  • No offline software option for customers that cannot use online version
  • User requires two hands: a potential safety hazard
  • Cannot be used in the rain
  • Cannot detect several sound sources simultaneously
  • Low acoustic image resolution
  • Manual frequency selection requires acoustics expertise
  • Confusing high ultrasonic frequencies with decreased sensitivity and a short detection range
  • Manual data export
  • Use only small circle in the middle of the screen for detecting and analyzing PD

Summary

To summarize, NL Camera offers the following benefits over other acoustic instruments: Locates the most critical problems quickly, enables surveying fully operational grids, has maintenance and repair plans; and requires minimal training.

Moreover, NL Camera offers the following benefits over thermal cameras: Detects problems extensively at an early stage, and locates all types of partial discharge.

In addition, NL Camera offers the following benefits over UV cameras: Detects problems extensively during regular working hours, and locates all types of partial discharge.
