Protect your Facilities – Using Furse Surge Protective Devices (SPDs)
Today, our ever growing dependence on Electronic Systems to drive Processes, Production and Services in business has become absolute & total. These vulnerable Electronic Systems and components which are the heart of every facility should be protected from the ravaging effects of Lightning strikes and Surges. In fact, loss of these systems would cripple Industrial, […]
A World of Earthing Solutions
Earthing (Grounding) is the bedrock of ALL electrical infrastructure and responsible for about 80% of all Power Quality problems. Once earthing is properly taken care of, profitability is the result, as downtime is reduced, maintenance costs is cut, safety of critical equipment enhanced. Ultimately leading to seamless operations and productivity. Indeed Poor Earthing practices wreck […]

DERATING TRANSFORMERS – A WAY OUT OF HARMONICS
One way to protect a transformer from harmonics is to limit the amount of load placed on it. This is called “derating” the transformer. The most rigorous derating method is described in ANSI/IEEE standard C57.110-1986. It is somewhat impractical because it requires extensive loss data from the transformer manufacturer plus a complete harmonic spectrum of […]
Harmonic Survey – Guidelines
Harmonics are troublesome but cannot be avoided. However it is as a result of automation, modern electronics, with direct consequences. The objective being to locate, mitigate and optimize productivity. Harmonics are indeed a strange bedfellow that must be managed and first step towards the solution is to know where to find them. GUIDELINES A harmonic […]
Power Factor and Why It Matters
Power Factor is a measurement that compares the real power (watts) being consumed to the apparent power (Volts-Amps) of a load. A purely resistive load would have a power factor of 1.0 What does it do? The power available to perform work is called real power (kW). Inductive loads such as motors, transformers, and high-intensity […]
Surge Protection A to Z – All You Need To Know
Electronic systems have become central to virtually every aspect of our lives from PCs and building management systems in the office to automated petrol pumps and barcode scanners at the supermarket, factory, banking & financial institutions, aviation and much more. Loss of these systems would cripple Industrial, Commercial and Government organizations alike. The importance of […]
Harmonics – An overview
Harmonics are by-products of modern electronics and automation. They are especially prevalent where there are large number of personal computers, adjustable speed drives and other types of equipment that draw currents in a non-linear manner (short pulses). The consequences of harmonic distortion in our commercial and industrial establishments are not necessarily evil, but an issue […]
Lightning Protection (Structural) – Key Design Considerations
Lightning is one of nature’s most powerful and destructive phenomena, yet it is the most under rated weather hazard. With awesome amount of electrical energy (measured upto over 200,000 Amperes), wrecking tremendous havoc to life and infrastructure on its trail across all sectors, despite its brief duration of fractions of a second. The consequences of […]
400-mile-long Lightning bolt over Brazil is biggest in recorded history
On Halloween in 2018, the sky tore open above Brazil. A single gargantuan lightning bolt sliced through the atmosphere over the country’s southern tip, stretching more than 440 miles (700 kilometers) from the Atlantic coast into the edge of Argentina. According to a new analysis from the World Meteorological Organization (WMO), this epic “megaflash” was the single longest […]
