AM series protection relay are applicable to the user substation
which the input voltage is 35kv and below. We adopt mature
technology solutions to ensure the quality of the AM relay.The AM
relay are widely used in substations, subsection posts and ring
main units for office buildings, commercial buildings,
communication buildings, mine buildings and so on. Protection

Remote control √ FAQQ: How to set the CT and PT ratio of the
protection device?A:The protection device can set the CT and PT
ratio through the fixed value menu. For example, the current
transformer is 75/5 andthe voltage transformer is 10/0.1, then the
CT ratio is set to 15 and the PT ratio is set to 100.Q: How to
distinguish the model when place order of AM3SEthat a single line
protection and transformer protection?A: A AM3SE is suitable for
circuit protection and transformerprotection. No need to
distinguish between models when placingorders.Q: When the voltage
is three-phase three-wire system, does the current have to be
connected with 2CT?A: The voltage wiring mode and current wiring
mode of the protection device can be set independently, and can be
connected freely.Q: How to confirm whether the anti-trip function
is configured?A: If the circuit breaker is equipped with anti-trip,
the device does not must be equipped with anti-trip; if the
circuitbreaker does not have anti-trip, you need to configure the
AM5-FT anti-trip module. (If DC48V is selected as theoperating
power supply, the anti-trip box is not optional, and the circuit
breaker must be equipped with anti-tripfunction; if you choose AC
anti-trip, please note that AC and DC general anti-tripping)Q: How
to purchase suitable protection devices?A: Before ordering, it is
recommended to consult related engineers, select the appropriate
protection model,and then fill in the corresponding selection
table, and place the order after confirmation by the
engineers.Customer /* January 22, 2024 19:08:37
