Recommended Solution:
Separate the sensing cable away from the HV power and grounding cables.
If not possible, then insulate with PVC spiral sleeve wrap or hold-down clip or both
If there are still interference from these HV sources and/or poor grounding installation in the
building (especially retrofitted old building), then install ELSA supplied ferrite-core filter and AC
filter to minimize it.
