  • Lightning Mast Protection Systems

    LBA Group, Inc

    Area protection for fixed and portable assets - LBA Technology offer the PLP-30 family of fixed and portable lightning protection masts and kits. Based on a light weight, rugged 30 foot (9.1m) aluminum mast; various mounting styles, grounding systems, and UL Listed air terminals are offered. PLP-30 lightning mast components are under 9 feet (2.7m) long for easy surface or air transport and rapid field installation.PLP-30 Lightning Masts are recommended for a wide range of lightning protection applications where it is impossible or undesirable to attach conventional lightning terminals. Other models in the series share the same attributes and differ only in height and weight.PLP- 30 Lightning Masts provide a cone of protection within which lightning charges are diverted to the mast and grounded instead of to the protected object. Multiple PLP-30 masts may be used to protect extended areas. Protected areas may be determined by use of the widely accepted "rolling sphere" concept. For example, a single PLP-30 mast will protect 8 foot (2.4 m) high portable buildings wholly within a 40 foot (12.2 m) radius. An array of five PLP-30 masts will protect a camp of portable buildings within a 25,000 square foot (2350 m2) area. Consult LBA Technology for specific layouts you wish to protect.

  • Solar Tracking and Pyranometers

    Sutron Corporation

    The demand for energy increased rapidly over the past few decades and the trend is not expected to stop in the near future. These made researchers focus on renewable energy sources due to the environmental pollution caused by the existing conventional energy sources. Solar energy is one of the renewable energy that has been under deep research. Unfortunately, the main problem with this solar energy is lack of efficiency. Different positions of the sun throughout the day causing the static photovoltaic modules position inefficient. This paper discusses design of two-axis solar tracking system that considers multiple input parameters such as solar radiation and photovoltaic module output power for more efficient solar tracking algorithm. Some of solar tracking system conducted by other researchers uses various types of sensors including light dependent resistor (LDR) which is not efficient and can be easily affected by external environmental factors. Instead, this paper proposes the usage of pyranometer for measuring solar radiation as one of the input parameters. The solar tracking system controlled by PIC microcontroller that collects multiple input parameters and uses developed algorithm to control stepper motor movement for optimal photovoltaic module positioning.

  • Measure of Harmonics & Flickers

    Ofel Engineering Srl

    The formal definition of "flicker" is the "impression of instability of the visual sensation induced by a light stimulus whose luminance or spectral distribution fluctuates over time".The flicker can be considered as a symptom, deriving from the modulation of a load (the DUT) and the effects that this produces on its supply voltage. While the DUT is connected to a voltage source with a finite impedance, any modulation of the load will cause voltage fluctuations on the supply line.The EN 61000-3-3 standard focuses mainly on the limitation of such fluctuations and consequent flicker on low-voltage public power systems. Voltage variations produced by electrical and electronic equipment when tested under the specified conditions must not exceed 4%.

  • Radiation Detectors

    PCE Instruments

    A radiation detector is a device for measuring nuclear, electromagnetic or light radiation. A nuclear radiation detector identifies nuclear radiation by measuring the emission of ionizing radiation of alpha particles, beta particles and gamma rays. Also referred to as a geiger counter, a nuclear radiation detector consists of two main elements: the processing electronics and the geiger tube. The geiger tube is filled with low-pressure inert gas like helium, argon or neon. If radioactive radiation occurs, the inert gas is ionized. An anode within the geiger tube registers the quantity of ionized particles numerically correlating with the strength of the radioactive radiation. The radioactivity measurement is then displayed on the LCD screen of the geiger counter or nuclear radiation detector.
