Boiler systems are major inancial investments, yet the methods for protecting these invest-ments vary widely. Proper maintenance and operation of boilers systems is important with regard to eficiency and reliability. Without this attention, boilers can be very dangerous (NBBPVI 2001b). 9.2.2 Types of Boilers (Niles and Rosaler 1998)
Jul 24, 2017 · The designation of 1,000 volts as low voltage has been chosen to be consistent with NFPA 70E and NFPA 70. However, NFPA 70E provides the same approach distances for voltages between 751 volts to 15 kV, and refers to voltage above 600 volts as medium voltage in its Annex D. NFPA 70 provides different requirements for voltages below 600 volts

Jul 15, 2015 · The common denominator for these equipments is the dielectric substance used. In view of the worlds reduce carbon footprint and elimination of global warming potentials new dielectric fluids and gases have emerged and have crept into the electrical power installations. Determine the components and operations of medium voltage and high
Oct 28, 2016 · Wiring and Bolted Connection Checks for Switchgear and Switchboards. 1.) Bolted electrical connections should be inspected for high resistance, either by use of a low-resistance ohmmeter (DLRO), calibrated torque-wrench, or infrared scan.Loose bolted electrical connections can lead to higher energy consumption and eventual equipment failure if not properly addressed.
We currently participate throughout engineering, operation and maintenance in high, medium and low voltage power, thermal and electrical energy generation projects, as well as in backup systems. Each company that integrates the group is characterized by its years of experience, leadership and operation under world-class quality standards.
If data and communication lines are connected to business equipment, these connections or lines must be protected from electrical surges, just like the power lines. Low voltage communication circuits can be damaged by a voltage spike that would not be severe enough to damage AC power circuits of the same equipment.
Arc Flash Clothing & PPE. Arc flash clothing and protection equipment including coveralls, gloves, helmets, face shields and general head-to-toe PPE is used to protect against flashover but will not prevent arc flash hazards. Consequently, PPE should be used as the last line of defence when implementing a documented electrical safety plan for maintenance, repair and diagnostic procedures
