Winding temperature indication
The 852Plus is the industry standard Winding Temperature Indicator / Oil Temperature Indicator, (WTI / OTI). Features include full monitoring of fan and pump running currents with ‘deviation from normal’ alarm relay output.
In addition to the 852Plus, the 852-2xx and 852-3xx provides a dual display on all models continuously indicating Hot Spot and Top Oil temperatures. The 852-2xx offers a winding temperature for one to two windings with multiple output relays for complex cooling systems. The 852-3xx offers a winding temperature indicator with three windings. Additional features include: 1 to 3 gradient selection, optional auto cool mode, allowing cooler exercising at timed intervals between 1 and 30 days. Full isolation is maintained between input and all outputs for maximum system integrity.
The 852Plus has been awarded National Grid approval with Type A status for unrestricted use on SuperGrid transformers at all NGC substations.
Accessories include:
Standard and custom PT100, (resistance temperature detectors)
Miniature measuring CT’s, (current transformers)
