Cast Resin Transformers are constructed with their HV high voltage windings encapsulated in resin and are an excellent alternative to traditional oil immersed transformers. Cast resin transformers encase the windings in epoxy resin : these HV high voltage cast resin transformers simplify installation since they are dry, without cooling oil, and so require no fire-proof vault for indoor installations. The epoxy resin protects the high voltage transformer windings from dust and corrosive atmospheres.

ABB LV Low Voltage Surge Arresters
ABB LOVOS-5 ABB LOVOS-10
ABB Surge Arresters for Low Voltage Overhead Line Protection
ABB low voltage surge arresters LOVOS-5 and LOVOS-10 are a new generation of LV surge arresters ensuring electrical protection of overhead lines, electric energy receivers, distributing transformers and low voltage electrical equipment. Specify and install ABB LOVOS type surge arresters to protect low voltage power equipment from the effects of lightning and switching overvoltages.
ABB low voltage surge arrester types LOVOS-5 and LOVOS-10 selection criteria : continuous operating voltage Uc, voltage protection level Up and energy absorption capability.
Applications for Low Voltage LV Surge Arresters
The ABB LOVOS range provides protection along LV overhead lines, cables, motors, switches, any equipment connected to the line, from the LV side of distribution transformers up to measuring instruments.
Typical places of installation
Low voltage switchgears, distribution transformers (LV side)
Transition points of insulated and uninsulated, overhead and underground lines and cables
Electricity service entrance locations to buildings (in cabinets or at poles)
At junctions (branching])
Every 500 / 1000 m of overhead line in locations of high lightning activity
At the end of dead-end feeder line
At the sealing ends of inserted cables
At any apparatuses connected to secondary voltage source
ABB LOVOS Low Voltage LV Surge Arresters
ABB LOVOS-5 and ABB LOVOS-10 Low Voltage LV Surge Arresters
The principal active element of ABB LV low voltage LOVOS surge arresters is a metal oxide varistor characterised by high non-linearity - at a working voltage mainly a capacity current flows smaller than 1 mA. Any voltage increase causes a large increase of current flowing through the varistor, leading in turn to immediate limitation of further voltage increase on arrester terminals. When the overvoltage disappears, the surge arrester immediately returns to its basic state. Surge arresters are equipped with a disconnecting device, that disconnects the surge arrester from the low voltage electricity network if it becomes damaged as the result of overvoltage of too high energy or inadmissable voltage increase in the system. If such a situation occurs then the bottom terminal of the disconnecting device is rejected by the spring inside - this terminal remains suspended on an insulation leash.
ABB LOVOS-5 and ABB LOVOS-10 LV Surge Arresters - Advantages
Easy assembly and connection of ABB LOVOS surge arresters
Disconnecting device also fulfills function of damage indicator
Large choice of ABB LOVOS surge arrester accessories
Casing resistant to UV radiation, non-flammable
Maintenance free low voltage surge arresters
All surge arrester accessories are made from corrosion-resistant materials

Tuning forks, with their stable resonant frequency, have been applied in numerous ways throughout many years. A modern application in industrial process control is the vibrating tuning fork level switch.The Jerguson Series 200 is a single point level switch which may be installed in any position in a pipe or vessel to detect the presence of a liquid.
The Series 200 employs a tuning fork style probe which vibrates at its natural frequency when in air. A piezoelectric crystal-system
is used to create a 1100 Hz vibration in the tuning fork. As the
tuning fork is covered by a liquid or slurry, a corresponding
shift occurs in the vibrating frequency of the tuning fork. This
shift is being monitored continuously and once a present threshold is exceeded, the output changes status.

Putting the SPARK into Virtual Training.pptxCynthia Clay
This 60-minute webinar, sponsored by Adobe, was delivered for the Training Mag Network. It explored the five elements of SPARK: Storytelling, Purpose, Action, Relationships, and Kudos. Knowing how to tell a well-structured story is key to building long-term memory. Stating a clear purpose that doesn't take away from the discovery learning process is critical. Ensuring that people move from theory to practical application is imperative. Creating strong social learning is the key to commitment and engagement. Validating and affirming participants' comments is the way to create a positive learning environment.
