Hydraulic Calculation Program

Dates :
9th & 10 December 2010

23rd & 24th June 2011


Please note: This course is currently only available to engineers from:-

• CE Electric UK
• Central Networks
• EDF Energy
• Scottish & Southern Energy
• Scottish Power
• United Utilities
• Western Power Distribution

This course will cover:

• Review of hydraulic calculations & equations
• Overview of the program
• Full coverage of the capabilities, functionalities and limitations of each module within the program
• Worked & delegates’ own examples

Course Profile

The Hydraulic Calculation Program has been prepared as part of the Strategic Technology Programme (STP) to provide suitably qualified employees of STP member companies with the capability to undertake the calculations required for the design, management, operation and maintenance of their oil filled cable systems: • Basic hydraulic design – Tank sizes, pp ratios, spare oil for systems requiring up to three tank positions • Calculation of setting pressures for user-selected values of ground, ambient and cable temperatures • Leak management capabilities – volume of oil lost, volume of oil required to restore pressure, predictions of times to alarm/switch out pressures • Calculation of cable oil contents and expulsions from user input of basic cable dimensional data • Calculation and plotting of P-V characteristic curves for individual tanks, ranges of tanks, and circuitspecific groups of tanks • Calculations for Impregnation Coefficient and Flow Tests, also P-V characteristic tests on oil tanks • Calculation of total, duct and CSA oil contents between any two points on a circuit The course will cover all capabilities and functionalities of the program in detail, illustrated by worked examples. Delegates are encouraged to bring profile and cable details for one of their own circuits, so that they can additionally use their own examples during the course. Attendance at this 2-day course is deemed to be an essential pre-qualification for anyone who is to be authorised to use the program, which will not be issued to persons who have not attended the course. Delegates should either have previously attended the EATL Oil Filled Cable course, or be fully experienced and knowledgeable with regard to the design, operation and maintenance of oil filled cable systems, and the associated hydraulic equations and calculations. Delegates who have been authorised by their companies to use the program should bring their laptops to the course, where their copy of the program will be installed.

Benefits of attending

As a result of attending this course delegates will gain: • A thorough understanding of functionalities, capabilities and limitations of the various modules of the Hydraulic Calculation Program

Who should attend?

• Engineers involved in the design, re-design (or diversion), operation, maintenance, leak location and repair of oil-filled cable systems
