Bil of power transformer?
B.I.L. stands for Basic Impulse Level for the transformer. It should be on the faceplate of the transformer.
What does BIL stand for in electrical high voltage substation?
BIL stands for Basic Impulse Level, it is the impulse voltage or power ( in the case of testing a transformer) or surge voltage in the case of lightning or switching, that a transformer or any other electric device is able to with stand. It refers to maximum voltage a device can with stand with out insulation breakdown which leads to a short circuit.

What does BIL basic insulator level really mean and its differences with Impulse withstand voltage and power frequency withstand voltage?
BIL is basic insulation level as per you or in other words it would be "basic impulse level" which implies the limit up to which an insulator could withstand impulse due to lightning strikes. Impulse is generated on the insulation due to the high voltage surges and spikes due to lightning strikes. BIL is generally much higher as compared to power frequency withstand voltage. In other words BIL is lightning Impulse withstand voltage. Impulse withstand voltage is the voltage that is generated due to switching operation and it's much higher than power frequency withstand, but BIL or the lightning withstand voltage is a the voltage level that an insulation can withstand during surge or lightning strikes.

What is BIL at 600 volts and at 480 volts?
BIL (Basic Impulse Level) is the maximum voltage a insulation system can withstand without breaking down. For 600 volts, the BIL would typically be around 10 kV or higher, while for 480 volts, it would be around 8 kV or higher. BIL is important for protecting equipment from voltage surges and ensuring reliable operation.
What is basic insulation level of 3.3KV Transformer?
The Basic Insulation Level (BIL) of a 3.3 kV transformer typically refers to its ability to withstand transient overvoltages. For a 3.3 kV transformer, the BIL is often around 12 kV for lightning impulse and 8 kV for switching impulse. These levels may vary based on specific standards or manufacturer specifications, but they generally ensure the transformer can handle expected electrical surges without failure. Always refer to the manufacturer's guidelines or relevant standards for precise values.
What is BIL lightning impusle withstanding voltage 150 kv bil?
Please refer Chapter 1, Page 2 of "Insulation coordination for power systems" by Andrew R. Hileman that gives a good description of the term BIL and BSL (Basic Switching Impulse Withstand Voltage).
What is the basic insulation level of various electrical equipments?
BIL or basic impulse insulation level is the dielectric insulation gradient of a material tested to withstand the voltage stress at a voltage impressed between the material and a conductive surface beyond the BIL rating, an electric tracking starts to occur which will then result into an arcing flashover to the conductive surface. In addition it is the capacity of an equipment to withstand mechanical stress..like lightning strike without causing any damage to the equipment...
What is the impulse withstand voltage?
Also known as basic insulation level (BIL): A specific insulation level, expressed in kilovolts, in accordance with which the complete system (including the line pole insulation to earth at every pole, the switchgear, the line isolators and reclosers, and the substations connected to the system, including their transformers) is designed and constructed. (NRS 039:1995)
Can the impulse withstand voltage be affected by altitude?
Yes. The IEC 60071.1 Std states a diminish withstand of aprox of 1% every 100mts above 1000mts. For example: for a 13.8kV system the insulation level should be of 95kV (interior). If the installation is going to be at 1,500mts then de minimum insulation level of your equipment must be: 95kv/(1-0.01*(500/100)) = 100kV BIL. The next std value for BIL is 125kV.
