The advanced digital earth resistance tester is multi-function and enables stackless earth resistance measurement without earth station disconnection or use of earth probes. It can also be used to measure soil resistivity ( specific earth resistance – Wenner & Schlumberger Array )
Customer benefit : Earth resistance test could be conducted while the installation is live and operational.
iii. Load survey : Portable power, energy and power quality analyzers enable recording of electrical parameters ay key location to establish load profile.

Power System Studies – Short Circuit, Load Flow & Protection Discrimination on ETAP
Power system studies covering the three basic requirement are conducted on ETAP software.
A short-circuit study is an analysis of an electrical distribution network that determines the magnitude of the currents that may flow during an electrical fault.
Comparing these calculated values against the equipment ratings is the first step to ensuring that the power system is safely protected.
Once the expected short-circuit currents are known, a protection coordination study is performed to determine the optimum characteristics, ratings and settings of the power system protective devices.
Short Circuit Study includes
- Data collection : Information on electric utility and customer’s installation is collected during field survey.
- Line diagram : A power system diagram indicating how all the components are electrically connected is generated.
- Computer analysis : Using ETAP software, the system data is use to input and the short-circuit currents at various points in the system are calculated.
- Tabulate results : The results are tabulated against ratings of equipment obtained from manufacturer. Discrepancy area are highlighted.
- Final Report : A detailed report including finding & recommendations for correction are generated.
Protection Discrimination Studies
- Short-circuit study : An analysis of available fault currents in the power system form the basis.
- Data collection : Detailed information is obtained on present settings and ratings of all protective devices.
- Manufacturer’s data : Each protective device has unique response characteristics, documented on manufacturer’s “time-current curves” that are used for analysis.
- Computer analysis : Allows the analysis to determine the optimum settings that will provide the best protection for the system.
- Tabulate results : The settings and ratings of each protective device are put in a table for comparison with present field settings and ratings.
- Final Report : A detailed report with recommendations is generated.
Load Flow Studies
Load flow studies primarily offer the voltage profile of the distribution network.
A load flow study calculates the voltage drop on each feeder, the voltage at each bus, and the power flow and losses in all branch and feeder circuits. Load flow studies determine if system voltages remain within specified limits under normal or emergency operating conditions, and whether equipment such as transformers, switchgear and conductors are overloaded.
Load flow studies help to
- Optimize component or circuit loading
- Develop practical bus voltage profiles
- Identify real and reactive power flow
- Minimize kW and kVAr loss
- Develop equipment specification guidelines
- Identify proper transformer tap settings
Load flow studies comprise of
- Field survey to obtain cable sizes and cable lengths, bus bar area, switchgear capacities, transformer and generator capacities in terms of thermal current, reactive power compensation.
- Input data into software to simulate conditions of operation that bring in changes in voltage, to identify conditions that result in either under or over voltage & overloading of current carrying components
- Generate recommendation to ensure maintenance of nominal voltages under various conditions of operations at key locations
Arc Flash Assessment & Labeling
What is an arc flash
Arc flash is a condition of serious electrical hazard and is a result of an electrical fault. Other conditions that may include accidental contact with live electrical equipment, breakdown of insulation, etc. Moreover an equipment that is not adequately protected or does not have the withstand capacity for the fault current is likely to pose arc flash hazard.
What happens during an arc flash
An arc flash is a sudden release of high energy which is proportional to available short circuit current at the location of fault. An arc flash is characterized with high explosion with temperatures of area surrounding arc flash reaching thousands of deg C in a fraction of a second. Such temperatures could set cloths on fire even from a significant distance, can cause severe burns, the bright light of flash & sound of explosion could bring temporary blindness and deafness. Molten metal of switchboards, copper from bus bars, nut bolts become shrapnel that fly in all directions at high velocity.
How to mitigate risk of an arc flash
Risk from an arc flash potential may not be entirely mitigated, however a better defense against it could be built. Arc flash protection is a step-by-step process.
First step towards safety from an arc is to carry out arc flash assessment.
An arc flash assessment includes identification of locations where arc flash hazard may exist and at what intensity.
An awareness session would follow an arc flash assessment report. It will discuss safety practices around electrical installation and use of PPE ( personal protection equipment ), defining various terms such as flash protection boundary, limited approach, restricted approach & prohibited approach.
The short circuit studies and an adequate & co-ordinated protective relaying offers realistic values of arc flash severity. Arc flash hazard at any given location is expressed as incident energy and is measured in cal / cm sq
Arc flash labels are fixed at all hazardous areas with essential data that warn and instruct personnel.
Saturn Pyro offers you
- Arc flash hazard assessment
- Protection co-ordination if required
- Arc flash labels
- Awareness program on arc flash assessment and use of PPE
Design of Earthing & Lightning Protection, Touch & Step Potential Testing
Earthing & Lightning Protection
Earthing design considerations have become more complex due to increased use of power electronics, automation & IT- equipment that require not only low impedance path for protective earth but also dissipation of earth leakage currents at the fundamental frequency as well a high frequency. It also means shaping of electrical field in ground around an earth electrode to enable control of hazardous voltage gradients.
Lightning protection design considerations apply to facilities with tall structures and also to sub stations, power generation plants, factories, etc. Lightning strikes involve high energy at voltages of 500 KV and currents 50 KA; although lasting for a very short duration of 10 to 50 micro seconds.
Lightning can cause deaths and injuries to human beings and severe damage to buildings and structures. The threat of damage to property and equipment is growing if IT systems, communication networks and sensitive electronic devices are being used without proper protection. When lightning strikes a structure, the very high current searches for the easiest path like metal pipes, power and communication wiring, metal railings — all of which are not designed to carry high currents. This generates heating, melting, fire and smoke.
Saturn Pyro advocates a systematic approach to earthing & lightning protection design which covers
- Soil Resistivity test ( Wenner or Schulmberger array ) with advanced instrumentation
- Soil stratification report review
- Design on software tools such as ETAP

Power Quality Management
Power quality refers to quality of key electrical parameters that affect the smooth and safe operation of an equipment : voltage, frequency, voltage waveform, harmonics, etc.
Electrical power received from electric utility can have issues such as sags & swells, sustained over and under voltages, interruption, transient over voltages, voltage harmonic distortion. These are due to collective effect of poor line regulation, lack of voltage regulators such as tap changers, sudden switch in or switch out of large loads, over head line faults such as falling of a branch, tracking by a bird and arcing load such as a steel plant.
Power quality may also be affected by equipment within a plant, such as power rectifiers & inverters, variable frequency drives, UPS, lighting, etc. Ironically the very equipment that are sensitive to power quality may contribute to power quality issues
Power quality issues are responsible for damage to or malfunction of critical equipment, loss of production, loss of revenue and high cost of repair / replacement.
