2024年12月25日 · There is no voltage fluctuations from one leg measured at the panel than the other. That is what's not making sense. When I put a load of 1300 watts on the circuit the voltage reading at the same receptacle will be 110Volts ( no load is 120Volts), but back at the panel during the load the circuit will read 120Volts.

2019年4月29日 · I have a customer (homeowner) that is testing the outlets in their house with a meter from Extech (CT70) for voltage drops. This meter is showing many outlets over the 5% threshold. The electrician who wired this house for me has wired 10+ homes over the years. They used 12 gauge wire in 20 amp circuits and 14 gauge wire in 15 amp circuits.

2023年10月19日 · If you consider the utility transformer fixed, then you should use 500 ft. But if the utility owns the 250 ft from the transformer to the meter, then typically the utility is regulated to provide a minimum voltage at the meter or thereabouts. In which case you are only responsible for the 250ft from the meter to the house, and can use that ...

2022年9月23日 · I am looking for a product suggestion for a panel mounted voltage meter. We have an existing voltage transformer connected to the 115 kV input to our substation, which outputs 0-120V. I'm looking for meter to read this 0-120V signal and display the roughly 115kV value seen by the voltage transformer. Technically, the voltage transformer is only ...

2013年11月26日 · If the breaker should open, you will get full line voltage across your meter. An autoranging digital meter might be fine, but an analog meter could be damaged. In addition to the contact resistance varying each time based on wiping action, etc., there may be a difference in resistance between closing unloaded and closing under load.

2009年4月6日 · It will detect low-voltage and in the past has always been checked against 480 prior to checking 4160. The literature says that's an acceptable means of test, but personally speaking, I would really like some certainty that the tester …

2011年6月13日 · Stray voltage may be an incorrect assumption. Is the "shock' being conducted from the street side of the meter connection or from the house side of the meter connection? If it is measureable, what is the actual reading? More detail in regards as to what is actually occuring will help to determine what kind of event is actually creating this ...

2019年6月13日 · Have an electrician install a power meter. Install a Current Transformer and a Voltage transformer to measure all electrical parameters of your 4160 motor. You can even communicate the reading in your computer.

2011年10月31日 · 6. Verification of Isolation (absence of voltage test) Is confirming the presence of voltage on the circuit to be de-energized prior to LOTO allowed? Seems that confirming the presence of voltage prior to LOTO would confirm that the meter is working properly and would confirm that the correct circuit is actually locked and tagged out...

2014年6月25日 · There is a phenomenon That happens with VFD's and distance it is sometimes referred as reflected wave. It makes voltage spikes at the motor that have the ability to puncture the motor insulation. This can also happen to the meter (and you). Personally, I would not trust a CAT4 @ 1000 volt meter to be safe at that distance. Just food for thought.
