WEBINAR - Load Flow Voltage Drop & Motor Starting Voltage Dip Studies
Venue: Digital Platform
Date & Time: 22 Aug 2020 (9:30 AM - 11:30 AM) Closed
CPD: 2
Closing Date Before: 19-Aug-2020 (Subject to change based on availability of seat)
Organised By Technical Division - Electrical Engineering (EETD)

SYNOPSIS

The session begins with a review of the three types of voltage-dependent loads – constant impedance, constant kVA and constant current – and compares the differences between starting and running motors. It will review the classical formula and a simplified formula for voltage drop, which is further simplified to provide a quick means to estimate the motor starting voltage dip in transformers and generators. The session concludes with some examples of motor starting dip with and without pre-starting loads and power factor correctio capacitors.

Pre-Talk Homework

Consider a 1 kV motor with a FLA = 20 A and an LRA/FLA = 5.0
FLA = Full-load Amp & LRA = Locked Rotor Amp
Assuming the use an ideal 1 kV source, calculate the following starting currents:
- DOL starting current
- Primary current, assuming the use of an ideal 1000/700 V auto-transformer
