Following are the Typical safe ability of Transformer, Generator and Cable to withstand Isc – short circuit fault current in multiple of its In – rated current, without damage to the equipment.
| Device / Equipment | Isc Fault Current as multiple of In | Safe Withstand Duration without damage |
|---|---|---|
| Transformer | Isc = 25 x In | 300 Sec |
| Generator | Isc = 30 x In | 5 Sec |
| Cable | Isc = 25 x In | 1000 Sec |
Sheet Metal for ASSEMBLY Enclosure are carefully selected considering Sheet thickness, Density and Melting point.
Utilization Categories indicate the type of Load and Duty Cycle of the load basis which selection of Switchgear should be done for the intended application.
Solar Radiation is electromagnetic radiation emitted by the Sun. Solar Gain is the Increase in Thermal Energy of a Object as it absorbs Solar Radiation.
Motor contribution is the Current feed back by Motor, due to rotating magnetic fied in rotor, into System during short circuit condition.
Coefficient of Thermal Expansion is the rate of change of unit Length/Volume per unit degree change in temperature.
Electric Shock is flow of external electric current through human body. Touch Voltage is the voltage between the energized object and the feet of a person.
For Electrical Network with non linear loads, Voltage Distortion limits are defined in IEEE 519. To ensure Quality Power Supply to Assets, Mitigate !!
In Powder coating process, CRCA surface is given Anti Corrosive Surface treatment, then Epoxy Powder is applied, melted and hardened.
Non Linear Loads are every where, which distorts the waveform, Hence analysis and Mitigation of Waveform Distortation / Harmonics is need of the day.
