The Transmission Line insulators are subjected to many stresses like electrical, mechanical, vibration, excessive heat, cold, dirt, pollution etc. which gradually deteriorates it’s IR values over the period of time. More the number of weak insulators in a string, there are more chance of breakdown of the line. Hence one must keep checking the strength of insulators periodically.

Leaky Insulator Detection is a new way of finding out weak insulators in the line, very easily, safely and quickly without climbing up the tower. This paper highlights the concept and importance of Leakage Current measurement on Transmission Tower Leg & Ultrasound Detection on Insulators to Identify the Leaky Insulators for predictive & preventive maintenance. The weak insulator also produces arcing sound internally, which can be picked up by Ultrasound Partial Discharge detection method to pin point the leaky insulator.

We provide effective products and solutions that are capable of Leaky Insulator, Ultrasound Detection on Insulators, Punctured Insulator, arcing sound, Arcing & Corona for various sectors in including Transmission, Distribution and Generation sectors etc.
