Technical FAQs 4

How much power does a 220 kV bus supply?

Thus total incoming power on 220 KV bus is (640+175+85) 900 MW. From the 220 KV bus two 220 KV single circuit lines are drawn at 90% loading to supply power to 220KV substations ‘b’and ‘c’ working at a diversity factor of 1.35 to cater 112.5 MW each.

What is the most motor-friendly inverter?

One example is the HES580 drive that we introduced at Busworld as the most motor-friendly inverter. It provides a cleaner power supply for traction motors to give bus operators more control over reliability and running costs.

How does an electric motor inverter work?

The inverter converts the direct current from the battery into the alternating current required by the electric motor. With its electronic control and monitoring of the electric motor, it ensures a safe and demand-based electrical supply for the electric drive. Are you interested in our solutions?

How does a 2 level inverter work?

Today, most electric buses, cars and heavy vehicles operate with 2-level inverters. These switch between positive and negative DC voltages to create an AC waveform. A side effect is that every time the inverter switches, it creates a voltage ripple.
