Current Transformer Secondary Open Detection Device 'KYS-01'
Equipment to protect current transformers ★★★ For distribution boards, control panels, distribution panels, and panels.
When the current transformer is open on the secondary side, the internal magnetic flux can reach saturation, which may lead to insulation breakdown and noise generation. This device detects the opening of the current transformer’s secondary side and protects the transformer. Features: - Connects to the secondary side of the current transformer to monitor the voltage of each phase, activating the secondary side short-circuit function when the overvoltage exceeds the set value. - Two contacts for alarms when the current transformer’s secondary side is open. - Allows for optional testing of recovery and short-circuit for each phase through recovery and short-circuit buttons. Functions: - Determines the presence of an open circuit using an LED. - Sets voltage sensitivity with a digital value (4 levels). - Sets operating delay time with a digital value (1 to 10 seconds). - Allows manual short-circuit/normal recovery operation for each phase separately. - Enables setting of relay usage status (activated/not activated) during alarm operation.
