Gas Insulated Switchgear | Source: Siemens Energy  What is Gas Insulated Switchgear?  A Gas Insulated Switchgear (GIS) is a type of switchgear used in electrical power systems that uses a gas, such as sulfur hexafluoride (SF6), to insulate the high-voltage components of the switchgear. The switchgear is typically used in high voltage substations, where the use of GIS has a number of advantages over traditional air-insulated switchgear. The main advantage is that GIS occupies much less space than air-insulated switchgear, making it possible to install high voltage equipment ..read more

What is Harmonics? Harmonics are sinusoidal currents whose frequency is an integral multiple of the fundamental frequency. In simpler terms, harmonics are a series of higher-frequency waveforms that are multiples of the original (fundamental) frequency in an electrical system. The fundamental frequency is typically 50 or 60 Hz, depending on the region. Harmonic currents are created by non-linear loads, which are devices that do not have a linear relationship between their voltage and current. These non-linear loads modify the waveform of the electrical current, resulting in the generation o ..read more

  What is Power Factor?  Power factor is a crucial concept in electrical engineering that represents the efficiency of power transfer in an alternating current (AC) circuit. It is defined as the ratio of real power (P) to apparent power (S), which can be expressed mathematically as: Power factor (PF) = Real Power (P) / Apparent Power (S) Real power (P), measured in watts (W), represents the actual power consumed by the electrical load to perform useful work. Apparent power (S), measured in volt-amperes (VA), is the product of the voltage and current in the circuit. It comprises b ..read more

How Motor Starting Affects Generator Sets?  Motor starting can have a significant impact on generator sets. When a motor starts, it draws a large amount of current from the generator set, which can cause a voltage dip or even a momentary loss of voltage. This voltage dip can lead to voltage-sensitive loads such as computers, electronic equipment, and lights flickering or shutting off.  If a motor is started using normal utility power, the high inrush current will only cause a minor voltage dip as the utility is a more resilient voltage source. However, when starting a motor using ..read more

  What is Service Factor?  The service factor (SF) is a measure of the periodically overload capacity, or the amount of extra load a motor can handle for short periods without sustaining damage. The SF is usually expressed as a decimal or a percentage above the motor's rated power or horsepower (HP). For example, if a motor is rated at 10 HP and has a service factor of 1.15, it can handle 11.5 HP for short periods without damage.

Ground fault protection is a crucial aspect of electrical safety, particularly for ungrounded and high-resistance grounded systems. In these systems, a fault to ground can go undetected and result in serious damage to equipment or even electrocution of personnel.  Ground fault protection is designed to detect such faults and quickly de-energize the circuit, preventing any further damage or harm to the electrical system.  In this context, ungrounded systems are those where no intentional connection exists between the system and the ground, whereas high-resistance grounded systems ..read more
