Pressure Tank Acceptance Chart

Calculate the drawdown of captured air type pressure tanks.  This chart applies to all bladder or diaphragm (captured air) tanks regardless of brand.  This chart happens to be provided by Wessels Pressure Tanks.

Voltage Unbalance Calculator

(EXCEL SPREADSHEET)

Use this spreadsheet template to determine voltage unbalance and also learn about the NEMA recommendations on this phenomena.  Voltage unbalance is a large factor in motor failures and more importantly, expected life of the motor.  Many facilities have voltage unbalance problems.

Current Unbalance Calculator

(EXCEL SPREADSHEET)

Use this spreadsheet template to determine current unbalance per NEMA specifications, and also learn about the NEMA recommendations on this phenomena.  Current unbalance is a large factor in motor failures and more importantly, expected life of the motor.

Irrigation Voltage Drop Calculator A

(EXCEL SPREADSHEET)

Calculate the voltage drop on low voltage irrigation system wiring.  The A spreadsheet allows you to enter the actual solenoid data into the sheet to calculate the voltage drop.

Irrigation Voltage Drop Calculator B

Calculate the voltage drop on low voltage irrigation system wiring.  The B spreadsheet uses preset solenoid data averaged out for the most common manufacturers (most irrigation valve manufacturers at this time use solenoids with almost identical solenoid requirements.

Voltage Drop Calculator 1 & 3 Phase

Calculate the voltage drop on any common US type power system with copper wire.
