Me Power Solutions

EMCO’s Solid State Voltage Regulating Relay Type EE 301- M is used for regulating the secondary voltage of power transformer with on-load tap changer . The required dead-band settings are set by setting the Nominal value and L & R levels independently. The Time Delay setting on the front panel eliminates the relay operations for momentary fluctuations of the regulated voltage, thus reducing the number of operations of the tap changer.

Key feature:

• A 2 Pole Oil Surge Relay is used in transformers to detect and protect against oil surge caused by internal faults or abnormal conditions.
• It features two poles for monitoring the oil level or pressure changes, triggering alarms or disconnecting the transformer if necessary.
• Provides early warning of issues like internal short circuits or other faults, preventing further damage to the transformer.
• Essential for ensuring transformer safety and operational reliability in electrical power systems.
