Application Guide. When the employer determines the job requirement group for the employee, this determination shall be based on the requirements of the employee’s duties. If the employee’s duties include tasks from different job requirement groups, the employee’s job requirement group is determined based on his or her primary duties or by determining a weighted job requirement group for the times spent in duties belonging to different job requirement groups. Using these times requires a task-specific working time record, or if this is not available, a work plan.
Application Guide. In principle, the employer’s consent applies always, except in cases where the absence of work constitutes an unauthorised absence.

Application Guide. SERIES CAPACITORS The impedance, normal rating, long time emergency rating, short time emergency rating, drastic action limit, and short circuit current withstand rating of a series capacitor bank shall be the values provided by the manufacturer or calculated by the owner at 60 Hertz and nominal system voltage e.g. 69 kV, 115 kV, 230 kV or 345 kV consistent with IEEE Standard 824. SHUNT CAPACITORS The kVA rating of a shunt capacitor bank shall be the rating provided by the manufacturer or calculated by the owner at 60 Hertz and nominal system voltage e.g. 69 kV, 115 kV, 230 kV or 345 kV consistent with IEEE Standard 18. SERIES REACTORS The impedance, losses, normal rating, long time emergency rating, short time emergency rating, drastic action limit, and short circuit current withstand rating of a series reactor bank shall be the values provided by the manufacturer or calculated by the owner at 60 Hertz and nominal system voltage e.g. 69 kV, 115 kV, 230 kV or 345 kV consistent with IEEE Standard C57.21. SHUNT REACTORS The kVA rating, losses and impedance of a shunt reactor shall be the values provided by the manufacturer or calculated by the owner at 60 Hertz and nominal system voltage e.g. 69 kV, 115 kV, 230 kV or 345 kV. The impedance of the shunt reactor shall be measured at full voltage as described in IEEE Standard C57.21.
Application Guide. 3.1 RIGID SUBSTATION BUSES The ampacity rating calculations of rigid, Aluminum or Copper, outdoor, exposed non-enclosed buses and conductors involves parameters such as ambient temperature, maximum conductor temperature limitations, wind speed, wind direction, solar gain, emissivity, and absorptivity. The maximum temperature at which the bus can operate is limited by loss of strength (loss of life) due to temperature cycles and mechanical movement due to expansion. Rigid substation bus ratings shall be assigned in accordance with IEEE Standard 605-1998.
Application Guide. The use of working times in accordance with the work roster is based on the company’s production needs and/or the needs of the employees. The working time in accordance with the work roster refers to shifts, the length of which can vary between four and ten hours. There can be several shifts of varying lengths in a week. The lengths of the shifts can also vary weekly or monthly. The weekly working hours can vary in shifts referred to in the work roster. However, the regular working time shall not exceed 50 hours. The weekly working time must average out at 40 hours in an adjustment period of 52 weeks. This shall be taken into considerations when drawing up rosters.
Application Guide. Overhead conductor ratings shall be calculated as described below at a rated power frequency of 60 Hertz and nominal voltage, e.g. 69 kV, 115 kV, 230 kV or 345 kV. MAXIMUM ALLOWABLE CONDUCTOR TEMPERATURE Conductor ratings are dependent on choice of maximum allowable conductor temperature, which is normally selected to control two factors: • loss of strength over time due to annealing, and • adequate ground clearances due to conductor sag considering the effects of non-elastic elongation (creep).
Application Guide. Current transformer ratings shall be calculated as described below at a rated power frequency of 60 Hertz and nominal voltage, e.g. 69 kV, 115 kV, 230 kV or 345 kV. INDEPENDENT (FREE-STANDING) CURRENT TRANSFORMERS These are current transformers that are purchased and installed separately from other equipment.
Application Guide. Line trap ratings shall be calculated using one of the methods described below at a rated power frequency of 60 Hertz and nominal voltage, e.g. 69 kV, 115 kV, 230 kV or 345 kV. Line Traps have limited overload capacity; therefore the continuous current rating should be selected to be above the winter four-hour emergency rating of the circuit in which it is installed. Furthermore, Line Traps must have a higher short-circuit capability and a continuous current rating greater than other any of the other components in the circuit (i.e. circuit breakers, disconnect switches, etc). RATING ALGORITHMS The rating methods used by various manufacturers are based on the following common elements: Ambient temperature ( a ); Temperature rise, which is a function of the I2R losses; A pre-determined maximum temperature acceptable for various line traps under normal and emergency conditions; Acceptable limits of loss of life of line trap due to the above. NORMAL RATINGS The primary considerations in defining the normal current rating of a line trap are ambient temperature and maximum allowable temperature rise. In the absence of a heat run tests, the manufacturer can calculate the normal current rating by a compensation method for a specific ambient temperature. Based on the premise that hottest spot temperature rise is proportional to I2R losses, the following equation can be used to determine a normal capability at any ambient temperature without exceeding the hottest spot design limit: TH TA TH TD IA = ID Where, IA = capability at ambient TA (amperes) ID = nominal rating of line trap, rated continuous current (amperes) TH = maximum hottest spot design temperature1 (C) TA = ambient temperature2 (C) TD = design ambient temperature3 (C) EMERGENCY RATINGS When defining the emergency current rating of a line trap, for ratings of twenty-four hours and less in duration, the emergency allowable maximum temperature limits of 30C above the normal allowable maximum temperature shall be utilized. Operation at the specified emergency allowable maximum temperatures shall not affect the accuracy of the tuning pack in the line trap. NEMA Standard SG-11 [Reference 1] specifies that the resonant frequency shall not vary more than two percent for ambient temperatures within the range of minus 40C to plus 40C. Emergency ratings for durations of less than two hours are determined based on the line trap’s Thermal Time Constant, which is a function of the heat storage capac...
