Trafford, PA – August 24, 2017 – Cleaveland/Price announces that it was recently awarded patent Nos. 9664710 and 9746498 for a sensory assembly system and method for monitoring power lines. The sensor discoveries covered by the patents are the basis for the Cleaveland/Price LineScope® power monitor for overhead lines.
The new technology distinguishes itself from other sensing methods in that, as a wireless system, it has the capability of measuring ground or neutral currents as well as provide accurate real-time current and voltage readings for each phase of the power line. While some wireless sensors can provide current and voltage readings to calculate power factor, VA, and watts values, they are unable to determine a ground current value. Through synchronized voltage and current readings from the three phases, the patented Cleaveland/Price system can analyze the readings and determine the net real time sum of the three currents to calculate a ground current value.
For electric utilities, ground current value is an important measurement in determining the health of the electrical system. The presence of ground currents is an unhealthy condition for an electrical system and can pose a potential health and safety risks as well as result in damage to equipment.
Cleaveland/Price is a switch engineering and manufacturing firm with a diverse product portfolio including outdoor group operated high voltage switches with ratings to 345 kV, hookstick operated switches for a wide range of applications, enclosed switches including isophase disconnects, and custom designed high voltage switches for special uses. The company also manufactures switch control motor operators that enable utilities to integrate almost any switch into a SCADA or smart grid system in overhead, underground, and padmount applications. In recent years, Cleaveland/Price has introduced a highly accurate line sensor for distribution and transmission applications as well as new remote terminal unit (RTU) designs.
