Installation manual

Documenting the system

Once you are happy that you have successfully commissioned the turbine you should record

the following details (see Section 8.5):

 Jets sizes installed

 Flow rate through turbine (As a check it is recommended that the exhaust water from the

turbine is collected to determine the flow rate of water through the jet, measure this by

noting the time to fill a container of known volume.)

 Output Watts (= amps x volts) (A DC current clamp meter is ideal for checking DC

current in different parts of the system during commissioning or troubleshooting.)

 Static pressure of pipe (turbine valves turned off)

 Dynamic pressure of pipe (turbine running)

 Generator equilibrium temperature, (see Section 8.4.8)

 Picture of installation

 Date for next service check (see Section 9.3)

Typical meter observations

Meter cabinet and resistive load

The meters above confirm that both units are operating: hydro 1 at 20 amps and hydro 2 at

11 amps respectively. The air diversion meter shows 3 amps diverted to the resistive load.

The battery voltage is appropriate for this diversion load to be operating. The picture shows

the air diversion element with a slight glow, indicating that it is working.

8.4.3. Optimisation of speed (PLT or TRG with no MPPT controller)

Optimisation is required for all PowerSpout turbines connected directly to battery banks. This

is very important and will make a significant difference to power generation. Once this point

has been found the rotor should be packed with the packing washers provided and the rotor

tightened - finger tight only.

Optimisation is to ensure you get the maximum output current from the turbine. You monitor

the current whilst making the changes described, visual optimisation is also possible as

described later.

Optimum magnet packing will change with changing pressure (smaller jets used for lower

flows will increase the pressure by reducing losses) and also with changing battery voltage.

Optimisation can be repeated when flow conditions change (differing jet sizes used) so you
