Asian Resources Int'l Limited MHG-T2 manual Power output has been falling recently

2. PowerPal has provided electricity for a while and suddenly the electricity stops.

If this instruction manual is not followed and power consumption is too high, or if there is a short circuit in an appliance the circuit breaker in the electronic load controller will trip. This will stop the electric current. If this occurs, check for possible causes and rectify. Reset the switch on the circuit breaker to the ‘on’ position.

3. Voltage is 220V under zero-load conditions but falls when a load is applied.

Either a capacitor in the control box has been damaged or excessive load has been applied. Reduce the load consumption to see if voltage stabilizes and if not have the control box examined by a competent electrician.

4.Testing in the stream showed that PowerPal was capable of producing the rated output power (1000W or 2000W, depending on model). However, after running the electrical cable to the house this output power was found to be less.

Due to resistance from the cable, long cable runs will result in a small loss of output power. Power loss over a 100m cable run is approximately 10W. For log wire runs it is possible to install a 4.75~10µf capacitor at the load end or otherwise to increase the cable diameter.

5.Power output has been falling recently.

Falling output suggests that the turbine is rotating more slowly than usual. Make sure that the enough water is entering the forebay and ensure that the source river is adequate for the flow being consumed. Otherwise, check the forebay and penstock filter and clean if necessary. There may be soft organic debris such as rotten leaves restricting the spear valve. Try running the valve completely closed and completely open one or two cycles. This may clear the valve of any foreign material and open it up to full power again. If that happens, then you should go to the forebay and be sure that it is clean, and eliminate the cause that allowed the foreign material into the pipeline in the first place. You can also check that the runner is free of leaves and other debris and that the turbine bearing has enough grease. Under certain conditions the generator may lose magnetism and result in loss of power. Its main winding may be re-magnetized by applying a 3V DC power source and energizing for approx- imately 30 seconds.

6.On starting, the control panel shows 220-240 volts and zero amps. The circuit breaker has been turned “on” with the user load “off.” No power goes to the ballast resistor.

Check the voltage at the right side of the transformer, it should be 220-240 volts. Check voltage at the left side of the transformer, it should be 18-25 volts. If not, the transformer is faulty. If yes, check the voltage at the terminals at the top of the circuit board. This should be 18-25 volts. Check the voltage at the terminals at the bottom of the circuit board. This should be AC, low voltage. If there is 18-25 volts at the top of the circuit board and no voltage at the bottom of the circuit board, then something in the circuit board is faulty. If that is the case, try adjusting the potentiometer as follows:
