Overcurrent Relay Curve Library Update
This update will fix data entry errors in the following overcurrent relay libraries that were shipped with OneLiner and DistriView prior to April 2010: ABB.RLY, COOPER.RLY, CUTLER-HAMMER.RLY, ELASTIMOLD.RLY, ELECTROFUSI.RLY, G&W_ELECTRIC.RLY, HI_TECH.RLY, KEARNEY.RLY, S&C.RLY, SHAWMUT.RLY, SIBA.RLY. The errors caused the program to use the minimum melt curve in calculating fuse total clear time in fault and vise versa. OneLiner and DistriView OC windows plot was not affected by these errors because the programs always include both total clear and minimum melt curves in fuse curve plot. See this readme.txt file for additional details.

Latest HASP Drivers
We always include a set of device drivers for the HASP key in the \network directory of the program CD. If these device drivers don't work for you, you may be able to get a newer and better version from the key manufacturer's web site http://www.aladdin.com/support/hasp/enduser.aspx You need Windows Administrative privileges to install the device drivers.
FOR NETWORK ACCESS
1. Download HASP_lm_setup.zip to get the latest version of lmsetup.exe, the Licensing Manager service installer.
2. Remove all HASP keys from the security server (the computer with the network key attached)
3. Execute LMSETUP.EXE to update the Licensing Manager. Accept all defaults.
4. Plug the HASP keys back.
FOR SINGLE USER ACCESS:
1. Download HASP_SRM_Run- time_setup.zip to get the latest HASPUserSetup.exe, the HASP SRM Run-time GUI Installation for installing the device driver.

Licensing Manager Is Too Old
If the message : "The License Manager is too old.", appears when you run OneLiner or Power Flow under network-key access, you must re-install the License Manager with LMSETUP.EXE at the PC with the key. Please see instructions above on how to install the latest HASP drivers for network access.

The transformer impedance is typically given in percent on transformer test sheets. One can break down the impedance into its resistance and reactance components using the transformer load-loss data, which are also given on test sheets.
