XT1 NANO represents a novelty in the area of magnetic lifters for covers, as it is folding, very easy to transport and has a double function! Light and ultra-compact magnetic lifter ideal for quick and multiple manual lifting of medium/heavy weight covers. With a weight of just 2 Kg has an incredible lifting force thanks to the latest neodymium type magnets. Opens and folds with one hand, attaches very strongly to the metal lids and can be easily detached with a lateral stroke. The foldability of the handle makes it really tiny for easy handling and transportation, can be stored anywhere even under vehicles seats. XT1 NANO has double function, turning it upside down can be used as lifting handle to grab the slots of the covers with the beak made in hard resharpened steel, its acute point can be used for chipping and breaking the hard incrustations that always clog the covers slots and allow grabbing and lifting asphalted or non-metallic covers where the magnet cannot be used. The plastic protection cap provided with the tool insulates the magnetic action to prevent unwanted contact with metal object during storage. XT1 NANO represent the “state of the art” in its application, is a concentrate of effectiveness and practicality, cannot miss in the equipment of modernly equipped teams.

Steam turbine is the heart of every thermal power plant. Steam turbines in the cogeneration plants primarily generate power and steam for captive consumption purposes, along with export of electricity to the state grid which enhances the energy efficiency and production capacity of process plants. This will not only result in considerable savings, but also leads to a sustainable supply of electricity and additional revenue from the surplus electricity generated.
Steam turbine in the power plant encounters continuos operation and maintenance concerns due to varying grid conditions and process demands. To counter this adequate protections and controls be connected to the turbine system for smooth and reliable operation. For the reliable and trouble free operation and protection of such industrial steam turbines, it is important to include steam turbine control and safety systems to avoid failures thus shutting down the turbine.
Protections and controls for steam turbines should be designed such that the protection system safely isolates the turbine during abnormal grid/fault conditions or shuts down any plant process equipment during abnormal conditions. Such protection and control systmes sense/ determine unsafe conditions and ensure that no single-point failure will affect the complete system reliability or availability. System failures are detected, annunciated, isolated and allowed to be repaired or replaced while the monitored system continues to operate on-line, increase realiability, reduce maintenance, improve diagnostics and employ more precise control onsteam turbines.
With over 4 decades of experience and continuos development in steam turbine technology, Triveni is the preferred brand of power producers internationally wherein steam turbines are engineered, manufactured and commissioned considering the varying grid / process conditions and safety of the system.
With an installed base of more than 3000 units worldwide, Triveni proves that its reliable and robust steam turbines are globally accepted. This paper presents a case study on Triveni’s solutions to the steam turbine control and protection system failures.
The probable causes of non opening of circuit breaker in isolating the fault when the respective protection relay has operated are due to no auxiliary power supply to trip coil of circuit breaker (failure of the mains supplying power to the trip coil) and failure of trip coil of circuit breaker
In case of no auxiliary power supply to trip coil of circuit breaker or failure of trip coil of circuit breaker, if the respective circuit breaker fails to trip even after initiation of trip command from the grid or generator protective relay, breaker backup protection (LLB) or generator protection relays initiates tripping of the next upstream circuit breaker, thus isolating the TG from the grid.

For sustainable energy
Sun is a potentially inexhaustible source for energy. The advantage of using solar energy is that it is free and super abundant. In the view of global warming, with energy policies calling for wide-scale use of renewable and sustainable technolgies, solar projects are proving invaluable in reducing the dependency on fossil fuel. While PV technology produces electricity directly from any sunlight, CSP technology uses mirrors to concentrate solar radiation into a receiver, where a transfer medium absorbs the heat and utilizies in a heat exchanger to generate steam or conventional regenrative water-steam cycle, which feeds a turbine to generate electricity. Various alternatives CSP technologies (Central Tower, parabolic Trough, Linear Fresnel) are available to produce live steam with diferent parameters, from saturated to the highest superheated steam conditions. CPS plants with an integrated thermal storage sytem like molten salt allow higher utilization of the power block, even in absence of sun, and with the possibility of producing electricity on demand.
Solar power technologies
Since past two decades, solar thermal energy has been a proven technology. Solar energy can be harnesses by incorporating different technologies and parabolic through collector type plant is most commonly used. Alternate technologies are fast catching up, such as Linear Fresnel colector plants with flat mirrors and central tower plants with slightly curved mirrors or heliostats. Thwe basic principle is the same for all three plant technologies. Mirrors concentrate the incident solar radiation onto a receiver where it is converted into heat that is used to produce steam to drive a steam turbine. Heat storage systems like molten slat tanks provide for power supply even during unfavourable weather conditions or at night. They significantly increase the number of full-load operation hours with optimal steam turbine efficiency.
