Wika HV MV Equipment advantage

Jun 05, 20203.5-Core Cables. A 3-phase system may have a neutral wire. This wire allows the 3-phase system to be used at higher voltages while it will still support lower voltage single phase loads.. It is not likely in such cases that the loads will be identical, so the neutral will carry the out-of-balance current of the system.The greater the degree of imbalance, the larger the neutral current.

  • Medium-voltage transformers: fundamentals of medium

    The first measurement is taken high-voltage to ground, the second high-voltage to low-voltage, and the final low-voltage to ground. Test results are pass or fail: Test results are compared to an empirically derived curve of insulation factor power vs. temperature (typical pass value for a distribution transformer would be 1.0% or less).

  • Gas insulated substation (GIS) versus Air insulated

    Oct 28, 20202. Maintenance. The failure rate of circuit breaker and disconnecting switch in GIS is one-fourth of that of AIS and one tenth in case of busbar, thus the maintenance cost of GIS is less than that of AIS over the lifetime. 3. Operation cost. The maintenance cost of GIS and AIS shall be equivalent.The cost for training in GIS is higher than in AIS.
