Tips for gathering evidence to demonstrate your skills

The important thing to remember when gathering evidence is that the more evidence the better - that is, the more evidence you gather to demonstrate your skills, the more confident an assessor can be that you have learned the skills not just at one point in time, but are continuing to apply and develop those skills (as opposed to just learning for the test!). Furthermore, one piece of evidence that you collect will not usualy demonstrate all the required criteria for a unit of competency, whereas multiple overlapping pieces of evidence will usually do the trick!

documenting power factor correction equipment installation details

following workplace procedures

performing relevant industry calculations

selecting power factor correction equipment, including:

obtaining and applying safety and relevant industry standards

selecting power factor correction equipment.

Evidence required to demonstrate competence in this unit must be relevant to and satisfy all of the requirements of the elements, performance criteria and range of conditions and include knowledge of:

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
