This product is a voltage indicator designed by our company according to user needs. The internal circuit adopts low-power light-emitting elements, which makes the power consumption of the whole machine low, the performance is more stable, and the reliability is higher. In order to facilitate the user’s on-site dual-circuit phase inspection, the phase test terminal can be set on the indicator panel, which is widely used in indoor high-voltage
electrical equipment with 3.6, 7.2, 12, 24, 40.5kV and frequency of 50Hz. It reflects the high-voltage live condition, and is matched with isolating switch and grounding switch, and can also improve the error-proof performance of the supporting products.
