The ARTM series electrical contact on-line temperature measuring device is suitable for temperature monitoring at cable joints/circuit breaker contacts/knife switches/high-voltage cable intermediate heads, dry-type transformers, low-voltage high-current equipment, etc. in high and low voltage switch cabinets to prevent them from running If the contact resistance of the contacts is too large due to oxidation, looseness, dust and other factors, heat generation becomes a safety hazard. This improves equipment safety, timely, continuous and accurate reflection of equipment operation status, and reduces equipment accident rate.
