Web26 aug. 2010 · I have been testing 480V cable and I obtained some of the following results: - 22 giga-ohms. I wanted to know if this seems like a "realistic" value to obtain. Note that these values were obtained at about 80 degrees F and a distance of 150 feet and #2 AWG conductors. As an example, I believe you can use a 500V or 1000V megger for 480V … WebA transformer with 12 V output, capable of providing up to 10 A of current, has a VA capacity of 12 V x 10 A, or 120 VA. The nature of power-supply filtering makes it necessary for the power-transformer VA rating to significantly exceed the actual power in watts that the load consumes.

WebTo check the electrical continuity of a megger we must connect both the leads together while the megger is ON Check the dress wiring of the device which is to be measured Make sure that all the connections are complete before testing. Check the three-phase motor is connected to delta or not, if so remove the links. WebTransformer capacity is rated in KVA (kilo-volt-amperes). The load voltage and load amps must be known to calculate KVA rating. * NOTE: We do not recommend loading a transformer above 80% of its KVA rating. When the KVA rating has been calculated, divide that number by 0.8 to get the minimum KVA rating needed. tenis adidas 4dfwd 2
