Webwattage ballasts (CWA, CWI), the measured line voltage should be within ±10 % of the nameplate rating. For reactor (R) or high reactance (HX) ballasts, the line voltage should be within ±5 % of the nameplate rating. If the measured line voltage does not conform to the requirements of the lighting

WebMar 1, 2024 · Impedance (pu)= square root of (resistance squared +reactance squared ) pu resistance = copper loss (kW)/Transformer rating (kVA);reactance is calculated based on parameters mentioned earlier. Voltage regulation = IR cos phi + IX sin phi (pu) Cos phi=power factor of load. Very interesting thread. Thanks guys. WebJul 29, 2001 · Schematic of the Regulated Lag Isolation Transformer type Ballast. Specifications similar to the above CWI Ballast. Note that this one has two isolated secondary coils - one is the Reactor coil, the other is the Regulation circuit connected to the Capacitor. I included a "Draining Resistor" in parallel with the Capacitors. philippines buying missiles from india
