Hi Everybody Can anybody explain how a Galvanic Anode Cathodic Protection system is tested ? Thanks

Hi every one A EHV cable was cut and left exposed to High moisture and water( no cap at either end of cut cable ) , i know about effects of moisture on cable specially on insulation deterioration also i know there are methods to dry out MV cable such as using N3 , To make the long story short...

Ladies and Gentlemen As We know Partial discharges occur when the local electrical field intensity exceeds the dielectric strength of the dielectric involved, resulting in localized ionization and breakdown , i was wondering how current will effect PD ?

Hi I am looking for a rubber gasket , 9mm and 60 shore .how can calculate the tension and pressure if i squeeze that inside a clamp to protect an electrical cable? basically i want to see if its possible to calculate the force applied from gasket to cable . Thanks

Gentelmen Two generators are feeding the same line through two different transformers and one common switchyard breaker, if I open the Breaker for that line both Gens will be off the grid and technically they should trip their 52G breakers because of either overspend or over frequency, but as...

Hello Gentlemen Can you please explain me why we usually have Positive MVAR for Gas turbines and Negative ones for Steam turbine? Is it because of different excitation system? Thanks in Advance.

Hello guys My VFD output Voltage, Current and frequency are fluctuating (what i show on VFD LCD), is that normal ? if not what can be the reason?any thing i can do? thanks in Advance.

Hi Can any body explain me how does sensorless control mode regulate the flux?also why they say not to use a VFD with(Base Volt/Base Freq) > (Nominal Volt/ Nominal Freq )? thanks in advance.
