FAQ
Q: What is the difference between the periodic timing of THC 15A and ordinary weekly timing?
A:

Periodic timing is a custom cycle interval timing mode, which can set an infinite cycle of "ON for X time + OFF for Y time" (e.g., 2h ON and 1h OFF cycle) without setting by day of the week. Ordinary weekly timing requires setting on/off times separately for 7 days. The THC 15A supports both modes, and periodic timing is more suitable for equipment requiring continuous cyclic operation (such as workshop exhaust fans and aquaculture aerators).

Q: What is the THC 15A Programmable Periodic Timer and what are its core functions?
A:

The THC 15A is a digital programmable periodic timer switch, compatible with AC 220-240V/50-60Hz voltage, with rated resistive load 16A/250VAC and inductive load 10A/250VAC. Its core functions include multi-group cycle timing (supporting timing range of 1min-168h), power failure memory (built-in lithium battery life ≥ 3 years), manual/automatic mode switching. It adopts 35mm DIN rail mounting and is suitable for scenarios such as cyclic start-stop of industrial equipment, agricultural irrigation timing, and commercial lighting control.

    Impact of DC Bias in Transformers at Renewable Energy Stations Near UHVDC Grounding ElectrodesWhen the grounding electrode of an Ultra-High-Voltage Direct Current (UHVDC) transmission system is located close to a renewable energy power station, the return current flowing through the earth can cause a rise in ground potential around the electrode area. This ground potential rise leads to a shift in the neutral-point potential of nearby power transformers, inducing DC bias (or DC offset) in their
