Product Details

Nmc’s microcontroller based automatic voltage regulating relays (avr relays) are latest technology based relays used for regulating the secondary voltage of power transformers with on load tap changer (oltc). The parameter settings are made through the front panel keys & are stored in nvram. Independent time delays can be set for first control pulse & subsequent pulses. Built-in tap displays tap number of power transformer. Oltc is blocked for uv, ov, oc, cf, minmax tap positions & tap fail . In manual mode, tap raiselower can be achieved through front keys. In test mode, relays, display and led indications can be checked. A pair of contacts are available for raise, lower, uv, ov, manual mode, cf, tf & oc. There are two nos. Of 5 amps c.t.’s available, one for the over current blocking and l.d.c. & other for measuring the current.
