GB/T 14598.7-1995 Electrical relays Part 3: Single input energizing measuring relays with definite time or self-definite time

This standard specifies the special requirements for the main characteristic quantities of single-input excitation measuring relays and protection devices with definite time or self-definite time. This standard applies to electrical measuring relays and protection devices with a single input excitation quantity, whose operating time is independent of or related to the excitation quantity. This standard does not apply to electric heating relays.
