Fault Localization and trouble shooting for Voltage Problem
Measurement Item	Nomal Measurement Result		Fault Measurement Result		Possible Cause	Trouble Shooting
Phase Voltage	MS5908C 198~242V(120V)		The Voltage is too high or too low		The Circuit is Overloaded	Redistribute the Circuit Losd
					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 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
Voltage Earth of Zero Line	<2V		>2V		Harmonic Interference	Increase Neutral Line Conductor, Install Electrical Filter or use Other Methods to Reduce the Harmonic Interference
Peak Voltage	MS5908C 280~342V(220V)		The Voltage is too high or too low		The Electron Device in the Circuit Results in the Electric Wave Distortion	Revaluate and Relocate (If necessary) the Electronic Device in the Circuit
Frequency	50Hz		The Frequency is too high or too low		The Supply Frequency is too high or too low	Consult the Electricity Department
