  32. REACTIVE POWER MANAGEMENT • TAP POSITION OF 400KV ICTs AT GAZUWAKA, VIJAYAWADA, KHAMMAM & HYDERABAD CHANGED. • MVAR INJECTION(220KV TO 400KV) THROUGH ICT AT GAZUWAKA BUS REVERSED. • MVAR EXPORT(400KV TO 220KV) THROUGH ICT AT VIJAYAWADA, KHAMMAM & HYDERABAD INCREASED. • APTRANSCO REPORTED IMPROVEMENT IN 220KV VOLTAGE PROFILE & REDUCTION IN LOSS BY 1%(APPROX.)
