Our LPS inspection methods
We offer two fully compliant methods, depending on your needs
Purpose
To verify the electrical continuity and quality of connections throughout the LPS. This ensures that lightning current can flow safely from the blade tip to the ground without excessive resistance or energy loss.
Method
This method uses a contact-based impedance measurement device.
The drone establishes a controlled contact with the receptor, a four-wire resistance measurement is performed, using a test current around 200 mA.
This allows for milliohm-level precision (mΩ) in identifying high-resistance points, poor joints, or connection faults without requiring rotor lock.
Readings are automatically logged and geo-referenced within the SkyVisor platform for reporting and analysis.
| Test Method | Purpose | Expected Values | Key Outcome |
|---|---|---|---|
| Continuity Test (Low-Ohm Measurement) | Verify electrical conductivity and detect faults in the LPS circuit. | 0–10 Ω (depending on cable length, joints, and grounding). | Confirms proper connections; identifies corrosion, loose joints, or open circuits. |
Purpose
Resistivity tests may fail in case of micro-cracks or the presence of spark gaps. Nevertheless the lightning strike itself, with its significant potential difference (Voltage) would ‘jump’ such gaps. That’s where the High Voltage test become handy.
Method
The drone, attached to a certified high-voltage generator, probes the lightning receptor. The test sequence goes from 0kV till 15kV until the circuit become passing.
The drone maintains a safe standoff distance and uses onboard monitoring to record the voltage level at which the circuit closes or insulation breaks down.
Readings are automatically logged and geo-referenced within the SkyVisor platform for reporting and analysis.
| Test Method | Purpose | Expected Values | Key Outcome |
|---|---|---|---|
| HV Test (Impulse Voltage Test) | Verify insulation strength and the system’s ability to withstand lightning current. | Voltage up to 15 kV, depending on turbine type and configuration. | Confirms insulation integrity and lightning withstand capability; detects breakdowns or leakage paths. |
