|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|
