power factor correction — equipment selection, including: definitions, concept of power factor and reasons for improving power factor situations leading to reduction of power factor consequences of poor power factor encompassing: demand tariff costs non-compliance with national service provider (NSP) and system energy loss design considerations encompassing: special conditions existing and the suitability for power factor correction (PFC) such as existence of distortion due to electronic loads, uninterruptable power supply (UPS) systems, and power generation facilities or complex electronic loads load profile and the nature of the load in all operating modes and with all possible sources of supply using three phase power recorders power supply quality issues in terms of voltage and frequency stability calculation of corrective VARs circuit protection issues and safety nominal location and arrangement types of capacitors to be used use of synchronous motor for large installations possibility of resonance discharge measures types of PFC controls low voltage (LV) PFC, high voltage (HV) PFC and solid-state switched compliance with Australian Standards (AS) encompassing: AS 1013-1971 Shunt capacitors for connection to power frequency systems AS/NZS 3000 Electrical installations (known as the Australian/New Zealand Wiring Rules) AS/NZS 3947 Low voltage switchgear and control gear testing and commissioning of power factor equipment, including controls relevant industry calculations relevant industry standards relevant job safety assessments or risk mitigation processes relevant manufacturer specifications and operating instructions relevant WHS/OHS legislated requirements relevant workplace documentation relevant workplace policies and procedures. |
