emt current transformer leak pointer

Sep 21, 2016Gaskets with poor seals are probably also leaking water and air into the transformer, in which case DGA samples should be obtained to check for high water and oxygen content inside the main tank. If oil levels are low and there is no evidence of external leaks, an internal leak could be present around the lower seal leading into the transformer tank.

  • Leakage Current Measurement Basics | Fluke

    6 mins readMay 09, 2013Any imbalance current comes from leakage from the conductors to ground or elsewhere. To measure this current, a leakage clamp meter should be able to read less than 0.1 mA. For example, taking a measurement on a 240 V ac circuit with all loads disconnected might result in a value of 0.02 A (20 mA) leakage.

  • Surge counter EXCOUNT-I - Hitachi ABB Power Grids

    EXCOUNT-I is capable of sensitively registering surges in combination with total leakage current. The values are shown digitally on an electronic display. EXCOUNT-I measurement of total leakage current is initiated by triggering a light sensitive diode on the sensor using a standard laser pointer. Without risking personnel safety this will initiate EXCOUNT-I to thereafter display the average value in milliampere.

  • When to pass a pointer to pointer as argument to functions

    You pass a pointer to pointer as argument when you want the function to set the value of the pointer. You typically do this when the function wants to allocate memory (via malloc or new) and set that value in the argument--then it will be the responsibility of the caller to free it.
