ubstation & Transmission Line Innovative Testing, Analysis and Maintenance Services 


Taurus Powertronics, an established market leader in manufacturing and trading Diagnostic Instruments also offer host of Innovative Testing, Analysis and Maintenance services which are essential to keep the Transmission Lines & Substations healthy and hence play a key role in supplying steady and uninterrupted power.


STITAM Services Include:-




If Surge Arrester is not healthy, it will fail to protect the equipment it is connected to in the severe Over Voltage condition. Surge Arrester drives a small amount of current under continuous operating voltage know as leakage current. This leakage current can increase over the period of time due to stresses the Surge Arrester undergo. Measuring the Third Harmonic Resistive Leakage Current gives us fair idea of aging or weakning of the Surge Arrester. Hence this must be checked periodically to avoid sudden failure / blasting and outage.



Floating DC Power System is required in substation to operate switch gears in case of emergencies. If an "Earth Fault" is present in this DC system, Circuit Breakers may not function the way they are supposed to and can cause major damage to the substation. At majority of the substations “Lamp Indicators” are used to indicate the existence of an Earth Fault in the system. But this method only makes us aware of the fault. It does not identify or pinpoint the exact location of the fault. The fault is traced by switching off individual circuit and observing the status of indicators first. Once the circuit is traced, then the particular circuit cables are checked and fault location is traced. This takes very long time and it is very dangerous to switch off critical circuit. 



Taurus STITAM offer to detect hotspots in Substation and Transmission Line using high end Thermovision camera. The main reason for developing hotspots in the system are loose joints. This happens due to poor workmanship, constant vibration or wear & tear of material. Hotspots are dangerous for the system and must be attended immediately to avoid breakdowns. A loose joint causes more resistance to current flow and hence get heated up. With the rising temperature the spot becomes hotspot and if not attended immediately, reaches to a breakdown point.



Taurus STITAM offer services for Measurement of Resistance & Impedance of Tower Footing. High energy generated during a lightening stroke or heavy surges must be discharged immediately through the tower body. The earthing provided to Tower legs should provide least resistive path to this high energy. It is possible that sometimes the earthing provided is not proper and can cause disasters during heavy surges or during lightening 



We Taurus Powertronics offer Ultrasound Scanning of Transmission line components and Substation equipment such as Surge Arresters, Transformer, Insulators, Joints, Circuit Breaker etc. These equipments emit different type of high frequency sound in case of any defect. With the help of our Ultrasound device this noise is captured and recorded. Using special software this noise is further analyzed to find out the exact cause of the fault / defects 



Taurus STITAM offers the service of Manually Inspecting the condition of Transmission Line and recording various aspects of Towers & Line. Transmission lines constantly undergo changes due to Rain, Heat, Pollution, Vibration, Load, Theft and also due to changes in surroundings like, trees, buildings, roads, new lines etc... To keep the line healthy and to avoid breakdowns, periodical patrolling is required. It is good practice to carry out Ground Patrolling every month and Monkey Patrolling (Climbing the tower) once in six months. Patrolling Records must be maintained for future use and analysis.
