Fault localization and trouble shooting for voltage problems

Measurement Item	Normal measurement result	Fault measurement result	Possible cause	Trouble shooting
Phase voltage	108-132V (120V) 198-242V (220V)	The voltage is too high or too low.	The circuit is overloaded.	Redistribute the circuit load.
			High impedance points are found in switchboard or circuit.	Locate the high impedance and repair or replace relevant parts.
			The supply voltage is too high or too low.	Consult the power supply department
Voltage to earth of zero line	<2V	>2V	Leakage current	Find the current source: Is there any multipoint ground? Does the equipment or device leak current?
			Three-phase imbalance	Check and redistribute the load
			Harmonic interference	Increase neutral line conductor, install electrical filter or use other methods to reduce the harmonic interference.
Peak voltage	153-185V (120V) 280-342V (220V)	The voltage is too high or too low.	The supply voltage is too high or too low.	Consult the power supply department.
			The electron device in the circuit results in the electric wave distortion.	Revaluate and relocate (if necessary) the electronic device in the circuit
Frequency	60Hz (50Hz)	The frequency is too high or too low.	The supply frequency is too high or too low.	Consult the electricity department

 

Fault localization and trouble shooting for voltage drop

Measurement Item	Normal measurement result	Fault measurement result	Possible cause	Trouble shooting
Voltage drop	<5%	The voltage drop is too high.	The circuit is overloaded.	Redistribute the circuit load
			Compared with power transmission length, the wire is small.	Rearrange the wire in compliance with the relevant standard.
			High impedance point exists between the circuit and switchboard.	Repair or replace the parts generating high impedance

 

Fault localization and trouble shooting

Measurement Item	Normal measurement result	Fault measurement result	Possible cause	Trouble shooting
Conductor impedance for live line and zero line	No. 14 line (2.0mm^2) <0.15Ω/m	The impedance is too high	The circuit is overloaded.	Redistribute the circuit load.
	No. 12 line  (3.3mm^2) <0.1Ω/m		The wire diameter is too small for the power transmission length.	Check the wire diameter and rearrange the wire accordingly.
	No. 10 line (5.2mm^2) <0.03Ω/m		High impedance point exists in the circuit or switchboard.	Locate the high impedance and repair or replace the parts
Conductor impedance for earth line	For personnel safety <1Ω	The impedance is too high	The wire diameter is too small for the power transmission length.	Check the wire diameterand rearrange the wire accordingly.
	For equipment safety <0.25Ω		High impedance point exists in the circuit or switchboard.	Locate the high impedance and repair or replace the parts

 

Measurement Item	Normal measurement result	Fault measurement result	Possible cause	Trouble shooting
