Switchgear Monitoring System

PyrOptic Offers Optimised Switchgear Thermal Monitoring

PyrOptic is a revolution in the way all the electrical connections and contacts can be managed in your plant and all over the world.It is economical and highly reliable making it suitable for mass deployment throughout electrical equipment and distribution systems. A PyrOptic system is made up strings of PyrOnodes, linked together by a continuous fiber optic loop. Each of the PyrOnodes contains a material that expands over an accurately controlled temperature range, this is captured to cut the POF and provide feedback of the developing problem. The available activation temperature ranges from 60 to 105°C. PyrOptic can be used to monitor the temperature of contacts and connections in switchboards thereby eliminating the need for routine inspections such as thermal imaging.

The economy, reliability and scalability of PyrOptic is achieved primarily by utilising permanent disruption of the fiber optic light path to signal trouble events. This feature makes PyrOptic suited to low probability, high consequence events such as failure of electrical connections and contacts. For example, electrical connections are inherently reliable however for the few that do significant business impacts and safety hazards can result. This is why routine inspections of electrical equipment is common in industry throughout the world and is fundamental to ensuring reliable and safe operation. Infact NFPA 70B recommends annual infrared inspections of electrical equipment in an attempt to manage the associated risk. Other monitoring systems can also address this issue however none come close to the simplicity, inherent reliability, economy or scalability that PyrOptic offers. These key features are fundamental requirements that enable mass deployment through electrical assets.

PyrOptic is the best switchboard temperature monitoring system to reduce risk in your business. Pyroptic can be distributed throughout electrical equipment, even oil filled, providing comprehensive coverage of all contacts and connections on a 24/7 basis. PyrOptic is easily integrated with your plant alarm systems to alert personnel of developing problems. PyrOptic is highly versatile and can be used in multiple applications.

Other features of PyrOptic include unlimited voltage application range as lenses can be used to transmit the light beam of a PyrOptic loop across air gaps thereby eliminating any kind of physical connection. The user can also use this option even where the fiber optic can be applied directly, such as in medium voltage applications. By doing so any potential tracking paths are eliminated. Furthermore the continuity check is extremely tolerant to system variance because there is no complex encoding or data that is transmitted in the light signal. PyrOnodes are completely sealed, rugged and small. They can be installed in tight locations and even directly in oil filled equipment. The optical loop is made using a high temperature plastic fiber optic (POF) featuring a Nylon 12 outer jacket, a material with extremely low moisture absorption and high chemical resistance.

PyrOptic can eliminate routine maintenance and inspection tasks while delivering superior risk mitigation outcomes at the lowest cost.

Fibre Optic Temperature Sensor

Electrical Connection Temperature Monitoring System Manages Risk 24/7 Using a New Concept That Levers Optical Loop Integrity

switchgear thermal monitoring

Inspection of electrical contacts and  connections in a plant across the globe is performed every day to manage the risk of unplanned outages and costly damage to electrical assets.These inspections are necessary due to the natural degradation of contact surfaces, vibration, incorrect assembly  stress relaxation of bolted joints. NFPA 70B suggests an annual routine for infrared inspections for many installations found in industry. PyrOptic has now completely changed the way the risk of electrical connection failure can be managed by applying a totally new concept that presents unprecedented scalability, economy, versatility and reliability.  PyrOptic is suitable for mass deployment throughout electrical equipment and the distribution systems. A PyrOptic system consists of one or more PyrOnodes. These PyrOnodes are linked by a continuous length of plastic fiber optic (POF). The temperature is monitored  at each PyrOnode and should the temperature threshold be exceeded the fiber optic loop integrity is compromised, providing  feedback of the developing problem. In order to monitor the loop integrity a fiber optic amplifier relay is used. However, loop integrity can also be checked by simply shining a visible light source on one end of the optical loop and observing its presence on the other. This way, one can monitor one to literally hundreds of connections on a single loop.

PyrOptic offers the most reliable, economical and distrubutable fibre optic temperature Sensor for electrical connections in the market. Our PyrOptic system consists of one or more PyrOnodes linked by a continuous length of plastic fiber optic (POF).

The activation temperature generally ranges from 60 to 105°C. The advantage of PyrOptic over other systems is the inherent simplicity that leads to fundamental system reliability, low cost and scalability. PyrOptic is also incredibly versatile due to its small size and sealed, rugged design allowing installation in restricted locations and even in oil filled equipment. PyrOptic leverages the mechanism of permanent disruption to virtually eliminate all connections in the detection system itself, further improving reliability, a key strength for managing the risk of uncommon yet hazardous events. PyrOptic provides the most scalable system that enables comprehensive 24/7 coverage of your electrical assets. Analog solutions are generally unable to provide such comprehensive coverage due to prohibitive implementation cost. The additional complexity also increases the risk of failure, there is nothing worse than spending more time fixing the monitoring system that the problems it detect. Unfortunately this is all likely to lead to additional lifecycle headaches and costs. Rather than adapting an off the shelf temperature sensor to address this issue, PyrOptic looked at the problem differently, recognised that analogue temperature monitoring is largely unnecessary in the vast majority of applications. By adopting a continuous optical loop, incredible economy and reliability is obtained over the lifetime of the monitored asset. The use of high temperature POF with Nylon 12 outer jacket enables system installation in oil filled environments. The POF can be applied directly to live electrical components at most common voltages. In high voltage applications lenses can be used to create air gaps in the optical loop. The same lenses can also be used to enable loop continuity check between stationary and moving equipment.
