Electrical Safety Solutions for High Resistance Grounded Systems

Some electrical applications cannot afford a shutdown. Such applications require an electrical supply system to control ground-fault voltage on driven equipment. This type of electrical supply system is known as HRG, which is a short form for a high resistance grounding supply system. This supply system is very beneficial and is used for several purposes. Let us have a look at its benefits.

  • It diminishes mechanical pressures in circuits that transfer ground-fault currents
  • It ensures the safety of people and properties close to the ground fault
  • It reduces electrical shock hazards for personnel
  • It reduces equipment destruction
  • A piece of faulty equipment can burn and melt, HRG reduces those burning or melting effects in faulty equipment
  • It reduces the reduction in line voltage while dealing with a ground fault
  • It can circumvent shutdowns in the case of a primary ground fault
  • It reduces the probability of arc flashes


A high resistance grounding supply system helps in reducing the probability of arc flashes (as mentioned above), so let us now discuss an arc flash. This flash is a light and heat produced as part of an arc fault. It is a sort of electrical discharge. This electrical explosion is a result of a low-impedance connection through the air to the ground or another voltage phase in an electrical system. It is right that HRG reduces the probability of arc flashes, and arc flash relays also known as arc protection relay helps in reducing arc flash energy by quickly clearing the current feeding the arc. The sensitive light inputs with current permissive detection identify low power phase to ground arc faults. The arch flash relay provides unmatched switchgear protection.

There is another highly efficient power saver product that provides integrated protection, frequency, and voltage stabilization. It is none other than the flexgen generator controller. It also provides automatic synchronization, active and reactive load sharing, programmable inputs and outputs, dead bus monitoring, and data acquisition. In a simple and straight sentence, flexgen generator controller is an electrical safety solution that is designed to withstand some of the hardest conditions. The product ensures that the generator is operating at the right frequency irrespective of the load.

There are many electrical safety products and solutions are available to withstand the hardest conditions to ensure safety all around. The range of different products is available online. The products are of high-quality and guaranteed. People can access the Internet and search for the most reliable online store offering a wide range of top-quality solutions at affordable prices. People can buy the required and most suitable products for their power management systems.
