Line Arresters Mitigate Ground Potential Rise on Towers & Improve Electricity Quality
While shield wires are efficient in reducing power frequency current flowing to tower grounding systems, it is more difficult to control the way a rise in potential of a HV tower grounding system is transmitted to a nearby grounding system of a LV installation sensitive to power frequency overvoltage.

Growing Demand for Non-Standardized High Voltage Testing
One of the factors behind the trend toward non-standardized laboratory testing is that network equipment is now being exposed to service conditions not covered by design and type testing. Also, requirements in some of today's standards are regarded as not stringent enough to reflect what can occur in the field. Read More >
