Measuring the Effectiveness of Lightning Protection Systems (LPS)

Specialized services which enable utilities to reduce vulnerability to lightning damage.

The Kinectrics Advantage

Kinectrics uses advanced expertise and practical experience to help clients when code-standardized LPS installations fail, or when other ongoing lightning-related issues are present.

Kinectrics’ lightning specialists perform unique, quantitative lightning protection system test procedures to investigate these problems. Our capabilities include evaluation and in-depth analysis, using measurements and scale modelling to discover where lightning energy may be affecting systems by causing unexpected upset or damage.

The Kinectrics team offers clients our advanced knowledge and long-term field experience. For four decades, the experts at Kinectrics (formerly the Ontario Hydro Research Division) have led and contributed to the development of several multi-national lightning-related industry standards and guides.

Kinectrics LPS related procedures ensure accurate data and reporting which enables utilities to effectively adjust systems or take practical counter measures to reduce vulnerability to lightning damage.

Kinectrics Lightning Services:

  • Review your plant’s vulnerability
  • Measure your Lightning Protection System (LPS) response to lightning
  • Measure how victim circuits respond to miniature lightning
  • Model and test the effectiveness of bonding, shielding, grounding
  • Conduct studies on nuclear / fossil plants and systems
  • Provide detailed reports
  • Deliver technical training courses

Lightning Mitigation Test Methods

Even for simple geometries, it is difficult to calculate both the lightning electromagnetic pulse LEMP effects in control wires, and the modeling of LEMP exposure within structures.

Having completed thousands of direct measurements of the transfer functions between a miniature lightning stroke current in structures, and the similarly-scaled voltages and currents on victim circuits, Kinectrics holds a strong advantage in the field.

The results can be scaled up linearly, as long as non-linear effects such as corona and soil ionization do not occur.  Both of these effects tend to reduce stresses, but they also indicate problem areas.  Kinectrics has the experience needed to identify threat levels which cause ionization.
